With these real-time verification methods, mailfloss helps you maintain a high-quality email list while reducing bounces and improving deliverability. [title] What is the recommended procedure for dealing with Accept All email addresses? [path] Get Started/ Accept All email addresses are the Achilles heel of email verification. In short, it means that we're not able to fully verify the validity of the email address, because all email addresses are valid according to the domain's mail servers. There's no right or wrong approach to dealing with these, but there are some questions you can ask to help you better decide if you should use them or not. ## Some questions to consider: ### Were these email addresses obtained via opt-in, legitimately to your email lists? If yes, it's probably safe to send to them. ### Were these email addresses bought or scraped? First, if this is in a B2C context and these were bought or scraped, stop and delete these email addresses right away. This is always a bad idea and likely illegal depending on your jurisdiction. If this is a B2B context, depending on your jurisdiction, this may or may not be legal, too. So always be aware of that and consult the appropriate legal entities. Second, if this is B2B and you want to put them into an email marketing campaign, we recommend you do not do this. You risk harming your reputation as well as getting banned from your email service provider and blacklisted from email providers should your bounce rates increase significantly. If you want to email them, you could target them with ads to an offer such as a lead magnet and have them explicitly opt-in to receive email marketing materials from you. If you insist on emailing them, you will want to test in small batches, and use software that is not your email service provider since this is likely against their terms of service. You could look into some cold email tools, instead. ### Have you ever emailed these email addresses before? If yes, and they have responded or engaged, then it's probably safe to send to them. In addition, observe the patterns of the companies involved. If the pattern of most of the email addresses is firstname.lastname\@domain.com, then tom.murphy\@domain.com might be good, whereas 8372botdude\@domain.com likely is not.

Copy the API Key or generate a new one. ![](https://mailfloss.com/wp-content/uploads/2021/01/6.-copy-API-Key.jpg) ## Step 7. Back in mailfloss, paste the API Key and click the Connect button. ![](https://mailfloss.com/wp-content/uploads/2020/12/8.-click-Connect.jpg) [title] Email verification Action Options [path] Floss options for an email service provider/ If you’re using mailfloss with a supported email service provider such (ESP), you have four or five action options at your disposal, depending on the integration. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/MBiyXPtROy3kfglvoHByA_1.png) The first option “Manually decide action on bad emails” will display emails deemed invalid so you can decide an action on them. With Manual Mode set, you can later decide to delete, unsubscribe, ignore, or report the status as incorrect for all contacts mailfloss determined as invalid.  Basically, we’re gonna show you the results on a list and you will decide what you want to do with them For more detailed information about the Manual option, [check this article](https://docs.mailfloss.com/action-option-manually-decide-action-on-invalid-emails). ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/oWkaFPtkJLOt3X-2bYkZM_2.png) The second option, “Auto-Unsubscribe invalid emails”, will automatically unsubscribe all failed results from your list. This action is irreversible. For more detailed information about the Auto-Unsubscribe option, [check this article](https://docs.mailfloss.com/action-option-auto-unsubscribe-invalid-emails). ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/14v9CHdcrpXigEinLeoSo_3.png" size="74" width="606" height="219" position="center" showCaption="false"} The third option “Auto-Delete invalid emails”, automatically deletes all the email addresses that failed the verification process, and is also irreversible. Once deleted, the contact is gone for good and you won’t find it inside of your lists anymore. For more detailed information about the Auto-Delete option, [check this article](https://docs.mailfloss.com/action-option-auto-delete-invalid-emails). ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/Mwu7CYwTdvFUF0A8Gvy5y_4.png" size="74" width="606" height="219" position="center" showCaption="false"} The fourth option, "Auto-Update custom fields/tags", will automatically update invalid emails, indicating when it was flossed and why it was marked as bad. We consider this an advanced option since you need to have knowledge of how the tags and/or custom fields work. And, you guessed right, this action is also irreversible. For more detailed information about the Auto-Update option, [check this article](https://docs.mailfloss.com/action-option-auto-update-custom-fieldstags-of-invalid-emails). ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/dO0K_7O-8-8JSscsSv-mM_5.png" size="74" width="606" height="219" position="center" showCaption="false"} The final option is “do nothing”. Basically, all this option does is send you an email report of the latest floss session, but doesn’t actually change anything inside of your ESP or mailfloss. This is most like boring, traditional email validation services, but is useful if you just want a report of the email verification statuses determined by mailfloss for the connected integration account and nothing more. For more detailed information about the Do not modify option, [check this article](https://docs.mailfloss.com/action-option-do-not-modify-emails). ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/GrwvB-rnYsNlOK6SLwkVe_6.png" size="74" width="606" height="219" position="center" showCaption="false"} [title] How to enable Two Factor Authentication (2fa) [path] Get Started/ Follow the instructions below to enable two-factor authentication (2FA). This is highly recommended in order to keep your account safe. Go to your main screen on your mailfloss app and look for your Account Settings. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/RJoaiCDDqHfZ-342DCOSe_1.png) Once on this screen, go to the Two Factor Authentication option. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/KWUUt4CU-xWXbj5WMedhd_2.png) By default, this authentication method should appear as disabled. Notice that you need to install one of the listed authenticator suggestions on your smartphone in order to continue with the process. Authy and Google Authenticator are good options.  Click on the switch when you’re ready. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/TMF5WJ7oXX6sbmNeQGboc_3.png) Now you should have a QR code on your screen, this is for connecting your mailfloss account with the authentication service. Open your authenticator and look for the scan option, then follow the instructions.  Once you have successfully scanned the QR code, write the 2FA code appearing on your authenticator app in the space below and press the "Enable 2fa" button. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/PP0LdTDK5lq7L4f4fn7Th_4.png) And it’s done! You should be redirected to a screen like this, confirming that now you have enabled the two-factor authentication method on your account. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/X0LpEkRUqALgvwBQ3cLH0_5.png) Now the next time you log in to mailfloss, you will be required to enter the 2FA code from your authenticator app before you are allowed access to your account. [title] Email verification Aggressiveness Options [path] Floss options for an email service provider/ Currently, mailfloss has 3 floss modes of aggressiveness which determine how aggressively mailfloss will perform email verification. These settings are only for connected email service provider integrations for maximum flexibility. Below is a brief explanation of each. ### Normal floss (recommended for most users), formally called Medium maifloss will floss for nonexistent, available, banned, deactivated, inbox\_full, illegit, invalid, bounced, and disposable email addresses. This is a sensible option and recommended for most users. For more detailed information about Normal aggressiveness, [check this article](https://docs.mailfloss.com/what-does-normal-aggressiveness-do). ### Aggressive floss (not recommended) mailfloss will do a deep cleaning of your email list. Anything that looks remotely bad will be flossed away. Choose this to maximize email deliverability, but only if you are cool with the consequences. There will likely be more false positives if your email list is new, and less false positives with older lists but they'll almost always be there. We recommend this option only if your list is really old or you want a really deep clean. We do not recommend Aggressive + Autofloss + Auto-delete or Auto-unsubscribe for most customers. This is almost never recommended. Please get in touch with us if you think you need to have your settings like this so we can talk you out of it. For more detailed information about Aggressive aggressiveness, [check this article](https://docs.mailfloss.com/what-does-aggressive-aggressiveness-do). ### Custom floss Somewhere between "Normal" and "Aggressive" floss aggressiveness, this allows you to customize everything in-between the two. Hover over the "?" tooltips to see an explanation of what each setting means.  For more detailed information about Custom Floss, [check this article](https://docs.mailfloss.com/what-does-custom-floss-do). [title] What is email bounce rate? [path] Get Started/ In email marketing, bounce rate refers to the percentage of email addresses in your subscriber list that didn’t receive your message because it was returned by a recipient mail server. There are two categories of email bounces including *hard bounce* and *soft bounce*. **What does a hard bounce mean?** This means an email has bounced back to the sender, undelivered, and without having been accepted by the receiving email server. The usually given reasons for a hard bounce are: - The email address doesn’t exist - The domain doesn’t exist - The receiving email server has completely blocked delivery. **What does a soft bounce mean?** Soft bounce is used to describe an email that has bounced back to the sender, undelivered, due to a temporary error. The usual reasons for this situation are: - Mailbox is full (over quota). - The recipient email server is down or offline. - The email message is too large. At mailfloss, we usually recommend removing email addresses that are full because we believe these are of low quality, potentially abandoned, and will hurt deliverability over time. Due to some verification tests and aggressiveness options, sometimes an email gets delivered to an address we flagged, this is what we call a false positive. This usually happens with Accept All addresses and increases if Aggressive mode is enabled. Learn more about false in [this article](https://docs.mailfloss.com/whats-a-false-positive-and-why-is-it-a-risk). Sometimes you may find that you got a bounce from an email address that seemed to be “good” and passed verifications tests. This is what we call a false negative, and you can learn more about false negatives [here](https://docs.mailfloss.com/whats-a-false-negative-and-why-is-it-a-risk). This usually happens with Normal mode as we don't run our full gamut of tests.  At the end of the day, our mission at mailfloss is to help you maintain a clean and healthy list, without sacrificing all those hard-earned leads and subscribers. That's why we usually recommend Normal mode for most users to maintain a healthy bounce rate, as flossing too aggressively will potentially remove too many false positives and remove perfectly valid email addresses. [title] Floss options for an email service provider [path] / [title] GoHighLevel email verification options using mailfloss [path] Floss options for an email service provider/ If you’re using mailfloss for GoHighLevel email verification, you have five options at your disposal. Before explaining the five options, make sure you have properly [GoHighLevel](https://docs.mailfloss.com/how-to-connect-gohighlevel-to-mailfloss) to mailfloss. You only need to do this once and from then on mailfloss will be able to automatically perform email verifications for the connected GoHighLevel account. Here’s a screenshot of the five options you have with GoHighLevel email validation: ![](https://archbee-image-uploads.s3.amazonaws.com/q0k5I8m97LQRRapz7DXqQ-Vm2oEoJYcEB8Oqi4emqhR-20250218-220320.png) The first option “Manually decide action on bad emails” will display emails deemed invalid so you can decide an action on them.

This action is irreversible. The third option, “Delete bad emails”, is also irreversible. Once deleted, the contact is gone for good and you won’t find it inside of GoHighLevel anymore. The fourth option is a little more advanced and intended for advanced users. It will update tags inside GoHighLevel, which you can use to sync with your other databases and CRMs. ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/q0k5I8m97LQRRapz7DXqQ-9WW34-_YMa_OHT6K7I4ba-20250218-220510.jpg" size="86" width="680" height="436" position="center" showCaption="false"} For more information about tags [check this article](https://docs.mailfloss.com/what-are-the-custom-fields-and-tags-that-mailfloss-updates-and-which-esps-support-them). The final option is “do nothing”. Basically, all this option does is send you an email report of the latest floss session, but doesn’t actually change anything inside of GoHighLevel or mailfloss. This is most like boring, traditional email validation services, but is useful if you just want a report of the email verification statuses determined by mailfloss for the connected GoHighLevel account and nothing more.

One common use of these features is to unsubscribe contacts from specific email lists or campaigns based on the mailfloss custom fields or tags.  For the purposes of this article, we'll use custom fields to describe the approach. The following article is a general approach to how to perform the unsubscribe. Each email service provider will have different steps to accomplish the following general approach. ## Custom Fields Custom fields are additional pieces of information you can store for each contact. To use custom fields for unsubscribing, you'll want to set up the automation as follows: 1. Select the custom field you want to set for unsubscribing. If you want to unsubscribe all contacts that failed a mailfloss test, we'd recommend using the custom field "mf\_validation\_passed" equals true. If you want to unsubscribe based on a reason category, use "mf\_reason" equals the desired category (e.g., "mf\_reason" equals "nonexistent"), and if by status, use "mf\_status" equals the desired status (e.g., "mf\_status" equals "undeliverable"). 2. Use this field to trigger a contact unsubscribe. 3. If configured properly, once a contact has the custom field added to it, the automation will trigger and proceed to unsubscribe the contact. Before using the custom fields or tags options to manage unsubscribes, we encourage you to ensure a solid understanding of how these features function within your ESP. If you're unfamiliar with these features or how they interact with your ESP, we recommend reviewing your ESP's documentation or seeking guidance from their support resources. ### Unsubscribe and Update Custom Fields Directly from mailfloss Now, if you have a Pro Plan, you can **unsubscribe and update custom fields at the same time directly within mailfloss** by following these steps: 1. Log into your mailfloss account. 2. Navigate to **Account > Integrations > Choose your integration**. 3. Scroll down to the **Action Options** section. 4. Ensure **“Auto-Unsubscribe Invalid Emails”** is checked. 5. A toggle will appear allowing you to **choose whether to Unsubscribe and Tag/Update Fields** at the same time. This feature helps streamline your workflow and ensures your email list stays clean and properly segmented with minimal effort. [title] How do I turn on/off automatic verification? [path] Floss options for an email service provider/ Automatic flossing/verification comes in three flavors, each with its own on/off switch: 1. Instafloss - instant, real-time verification 2.

Before explaining the five options, make sure you have properly [connected Drip](https://docs.mailfloss.com/how-to-connect-drip-to-mailfloss-oauth) to mailfloss. You only need to do this once and from then on mailfloss will be able to automatically perform email verifications for the connected Drip account. Here’s a screenshot of the five options you have with Drip email validation: ![](https://archbee-image-uploads.s3.amazonaws.com/q0k5I8m97LQRRapz7DXqQ-hzShtZscgYEFdbD1NGTEq-20250227-190952.png) The first option “Manually decide action on bad emails” will display emails deemed invalid so you can decide an action on them, like so: With manual mode set, you can later decide to delete, unsubscribe, ignore, or report the status as incorrect for all contacts mailfloss determined as invalid. ![](https://archbee-image-uploads.s3.amazonaws.com/q0k5I8m97LQRRapz7DXqQ-BqsdooPpyrX2SHcZIrH_P-20250227-191011.png) The second option “Unsubscribe bad emails” will unsubscribe the contact from Drip. This action is irreversible. You’ll see the contact in Drip in the "Unsubscribed" list. The third option “Delete bad emails” is also irreversible. Once deleted, the contact is gone for good and you won’t find it inside of Drip anymore. The fourth option is a little more advanced and intended for advanced users. It will update custom fields inside of Drip, which you can use to sync with your other databases and CRMs. For more information about our custom fields [check this article](https://docs.mailfloss.com/what-are-the-custom-fields-and-tags-that-mailfloss-updates-and-which-esps-support-them). ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/vwCmNPi03AfovFYo0VT7Q_3.jpg) The final option is “do nothing”. Basically, all this option does is send you an email report of the latest floss session, but doesn’t actually change anything inside of Drip or mailfloss. This is most like boring, traditional email validation services, but is useful if you just want a report of the email verification statuses determined by mailfloss for the connected Drip account and nothing more. [title] What's a false positive and why is it a risk? [path] Get Started/ ### What is a false positive? We define a false positive as any email address that fails at least one of our verification tests during a flossing process with a category reason of either "nonexistent", "deactivated", "inbox\_full", "unverified", or "accept\_all" but ends up being an actual address that poses no risk to your list. ### Not all false positives are created equal For example, if we mark an email address as "inbox\_full", it means at the time we ran the test this email address had a full inbox. It's very possible that by the time you email this address, the owner of the inbox could have cleared space in their inbox, thus allowing the email message to be delivered.  And the hardest false positives to detect, by far, are those in the "accept\_all" category. If an email server is set up this way, that means \****every***\* email address in this domain will be categorized "accept\_all", including the perfectly valid email addresses from this domain. While our proprietary Deep Clean engine is the best in the business at detecting real and fake "accept\_all" email addresses, it isn't perfect and there will still always be some false positives as a result. ### Lower bounce rate but higher false positives Our Aggressiveness Options are designed to allow you to choose how hard you want to floss. With **Aggressive** mode, you are bound to have a higher false positive rate but a lower bounce rate mainly because of the previously discussed "accept\_all" category. As such, we recommend Aggressive mode only **temporarily** until your bounce rate lowers to acceptable levels. There's a "help me decide" link beside the Aggressiveness options that you can click on to help you decide if Aggressive might be the preferred option until the bounce rate has lowered. ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/aJQ2nc06lG32fcCcaAbjf_1.png" size="60" width="534" height="59" position="center" showCaption="false"} ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/5S2WSAYtFZAYVWrpjC1ru_2.png" size="68" width="805" height="808" position="center" showCaption="false"} **Why do we recommend Aggressive only temporarily? ** Because you may be losing valid/deliverable email addresses being automatically unsubscribed and deleted from your account during your flossing sessions that are false positives. This is exactly why we don't recommend having Aggressive mode selected in your integrations at the same time as an automated mode like Autofloss or Instafloss, and other automatic options such as Auto-unsubscribe or Auto-delete (remember that both options are irreversible). ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/n0IJE_aypWuu8m33lfCW0_3.png) At the end of the day, our mission at mailfloss is to help you maintain a clean and healthy list, without sacrificing all those hard-earned leads and subscribers. That's why once your bounce rate is down to acceptable levels, we recommend switching back to Normal, which is a much more sensible option. Your bounce rate may increase, but there will be fewer false positives. [title] Status Definitions [path] Get Started/ You may have noticed a status column in the email reports we send to you. These statuses are what we recommend you base your decisions on mostly vs a simple pass/fail. A pass/fail is too simplistic with email verification except in the most dire of circumstances. In addition to the categories we already use, this should give you more flexibility on how you want to analyze the verification results. An email address will have a status of "undeliverable", "risky", "unknown", or "passed". They are based on the [category definitions](https://docs.mailfloss.com/category-definitions) an email address gets categorized as. ### Undeliverable These can't be delivered. It is strongly recommended to not send an email to these addresses. Categories that fall into this status are "invalid", "illegit", "nonexistent", "inbox\_full", and "deactivated". ### Risky These email addresses failed one of our verification tests and it is generally recommended that you do not send an email to these addresses unless you are confident real users are on the other end and engaging with your emails. You can check the engagement levels of these email addresses in your email service provider. Categories that fall into this status are "spam", "role", "banned", "available", "complained", "bounced", "disposable", and "blacklisted". ### Unknown We weren't able to definitively identify these email addresses. They passed nearly every test but it is unknown if these email addresses are valid because they failed with reason "accept\_all" or "unverified". Proceed with caution. The categories under this status are "accept\_all", "failed\_exchange",  and "unverified". ### Passed These email addresses passed the tests assigned to them. Keep in mind that the floss aggressiveness settings determine how many tests are run. Normal floss runs fewer tests than aggressive and is faster, while aggressive runs the full gamut of tests and is slowest. Custom floss settings run different tests based on your preferences. Floss aggressiveness settings only apply to our email service provider integrations since file upload or copy and paste run the full gamut of tests.

Ready to get started? Explore these integration options, and choose the one that aligns best with your requirements. We're here to support you every step of the way! [title] Which failed email addresses should I delete from my list? [path] Get Started/ We suggest deleting the email addresses marked as "Undeliverable". "Unknown" and "Risky" ones are only recommended for deletion if you must, or if you have bounce-related problems with those addresses. [title] What browsers work best with the mailfloss app? [path] Get Started/ We recommend Chrome browser for an optimal experience. Other browsers that work well with the mailfloss app are Firefox, Opera, and Brave. Edge browser has not been well tested with the mailfloss app and is not recommended. Safari is also not recommended, as there are reports of delays using the dashboard. [title] How to activate cached results for flossing [path] Get Started/ To avoid using credits on email addresses that were uploaded previously, you could turn on caching. This will use the cached data that we have from a previous upload rather than a credit, if we have any. Please note this is not recommended as the result is not a fresh, live result, and may result in higher bounce rates. Caching is currently in beta and may provide unexpected results. **Step 1.** Go to "Account settings" ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/GK_pSofSDxO8Pv0OtPiBY_1.png" size="34" width="246" height="333" position="center" showCaption="false"} **** **Step 2**. Click on "Beta Features" ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/m4IVzBGdrcMqrl30CnM8Q_2.png) **** **Step 3.** Once there, you'll see "Use cached results" as the first feature option. Click on the switch to turn it on. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/H4RmURbjV5pf7muE4KGxM_3.png) Don't forget to share your feedback with us! [title] mailfloss Recommended Settings [path] Get Started/ We usually recommend new customers to turn on Instafloss and set the aggressiveness setting to Normal. This covers the majority of our customers. If real-time verification isn't needed, or not included in your plan, Autofloss is recommended instead. We almost never recommend Aggressiveness setting and Instafloss/Autofloss. Initially, you may want to turn on "Manual Mode" and deal with the invalid email addresses inside of the mailfloss app until you are comfortable with the results and the process. Once you are comfortable with the process we usually recommend turning on an auto action such as Auto-unsubscribe or Auto-delete. That way mailfloss is entirely hands-off and set and forget. [title] Understanding the Risks of Sending to Old Email Lists [path] Get Started/ ## Common Issues with Old Email Lists Sending emails to an outdated list poses multiple risks, including: - **High Bounce Rates**: Older email lists tend to have a higher percentage of addresses that have been deactivated or abandoned. If many of your emails bounce, ISPs may classify your domain as risky, leading to lower deliverability and inbox placement. - **Spam Traps and Blacklists**: Some old email addresses may have been repurposed as spam traps. If you send emails to these addresses, your sender reputation could suffer, and you might end up on email blacklists. - **Increased Complaint Rates**: Subscribers who haven’t heard from you in a long time may not remember signing up for your emails. As a result, they may mark your emails as spam, further damaging your reputation. - [Yahoo/Hotmail-Specific Filtering Issues](https://docs.mailfloss.com/yahoo-and-hotmail-detection-limitations): - Yahoo and Hotmail have **deactivation policies** for inactive email addresses. If an address becomes disabled due to inactivity, it will generate a bounce message like: *"554 30 Sorry, your message to email\@yahoo.com cannot be delivered. This mailbox is disabled (554.30)."* However, these providers do not always indicate when an email address has been completely deactivated. - Some deactivated Yahoo addresses will produce a different bounce message: *"552 1 Requested mail action aborted, mailbox not found."* The distinction between a **disabled** and **deactivated** address is unclear, but Yahoo has become more aggressive in disabling accounts in recent years. ## Why Gmail, Hotmail and Yahoo Have Stricter Email Filtering Gmail, Hotmail, Yahoo, AOL, and other free email providers have become increasingly strict with email filtering and bounce detection. These providers aim to reduce spam and protect user inboxes, which means they implement aggressive filtering techniques that can affect email deliverability. This is especially true when sending to older email lists that may contain inactive or abandoned accounts. In early 2024, **Gmail** and **Yahoo** introduced several stricter requirements for email senders to enhance security and reduce spam. These requirements were implemented to ensure that emails are delivered to inboxes rather than spam folders and to protect users from malicious content. Here are the key updates: ### Gmail Requirements (Effective February 2024): - **Mandatory SPF and DKIM Authentication**: Senders must set up these protocols to verify their identities. - **DMARC Setup**: Required for high-volume senders, with an enforcement policy that can be set to "none." - **Domain Alignment**: The domain in the sender's From: header must align with either the SPF or DKIM domain. - **Valid Forward and Reverse DNS Records**: Necessary for sending domains or IPs. - **TLS Connection**: Emails must be sent over a secure TLS connection. - **Spam Complaints Below 0.3%**: Monitored through Google Postmaster Tools. - **No Impersonation of Gmail "From:" Headers**: To prevent domain spoofing. - **One-Click Unsubscribe Links**: Required for marketing messages. - **Message Format According to RFC 5322**: Ensures emails are properly formatted. ### Yahoo Requirements (Effective First Quarter 2024): - **SPF and DKIM Records**: Mandatory for all sending domains. - **DMARC for High-Volume Senders**: With a policy set to "none." - **Domain Alignment**: Similar to Gmail's requirement. - **Spam Complaints Below 0.3%**: Ensures low spam rates. - **Easy Unsubscription**: One-click unsubscribe links are required. By April 1, 2024, Google began rejecting emails from bulk senders that did not meet these new authentication requirements, further emphasizing the importance of compliance. These changes are part of ongoing efforts to improve email security and deliverability. ## Is it a Good Idea to Email an Old List? Our recommendation is that if you haven't emailed an address in over a year, then **no, it is not a good idea to email them**. While some people may think it seems like a good way to re-engage past subscribers, outdated email addresses can harm your sender reputation and email deliverability. Note that emailing addresses that haven't heard from you in a long time increases the likelihood they will mark your emails as spam. And if your spam rate goes above 0.3% for Yahoo and Gmail as of April 2024 (and likely more providers in the future), you'll be blocked completely. This scenario is not worth the risk, in our opinion. Instead, we recommend **finding ways to get subscribers to resubscribe** so you can get *new *consent from them. For example, uploading lists to custom audiences of various ad networks and social platforms is a good way to remind them of who you are and why they should resubscribe to your list. However, if you insist on emailing an old list knowing the risks, you should consider some best practices to reduce the impact on your bounce rates and sender reputation as much as possible. ## Best Practices for Sending to Old Email Lists **1. Clean Your List Before Sending** - Use an email verification service like mailfloss to remove invalid, inactive, and risky email addresses. - Identify and remove spam traps, role-based addresses, and temporary emails. **2. Segment the List and Send in Small Batches** - Divide your list into smaller segments based on recency of activity or past engagement. - Start with a small test batch to assess performance before scaling up. **3. Monitor Bounce Rates and Complaints** - Set up real-time monitoring for bounces, complaints, and unsubscribes. - If a segment generates a high bounce rate, stop sending to it immediately. **4. Use a Re-Engagement Campaign** - Send a ‘We Miss You’ email with an option for recipients to confirm their interest. - Offer an incentive (discounts, exclusive content) to encourage engagement. **5. Authenticate Your Emails** - Implement SPF, DKIM, and DMARC to verify your domain. - Use a dedicated sending domain and maintain a good sender reputation. **6. Monitor Deliverability Metrics** - Keep track of open rates, click rates, and spam complaints. - Remove unengaged subscribers after multiple attempts to re-engage them. **7. Use a Warming Strategy for Large Lists** - Gradually increase the sending volume to avoid sudden spikes in email activity. - Start with your most engaged subscribers and slowly expand to less active ones. **8. Consider Using a Separate IP Address for Older Lists** - This lowers the risk of damaging your main IP address reputation - This might not be an option depending on your Email Service Provider, but is worth considering if it is. By understanding these risks and implementing best practices, you can protect your sender reputation and improve email performance. Always remember to prioritize quality over quantity when it comes to email marketing!

[path] Frequently Asked Questions/ We are really accurate thanks to our Deep Clean engine, which runs additional tests that most other verifiers do not.  We don’t post accuracy percentages because we don’t believe accuracy percentages are…well accurate. There are simply too many factors involved to state a misleading guaranteed accuracy percentage. We believe accuracy percentages are a marketing ploy that our competitors use without the data to back it up.  Ideally, we strive for a balance between convenience, accuracy, and affordability, and try to keep bounce rates below 5%, ideally below 3%. Read more about our bounce rate goals [here](https://docs.mailfloss.com/high-bounce-rate-after-flossing). [title] How fast is mailfloss? [path] Frequently Asked Questions/ Speed is not a strong point of mailfloss. We are more focused on accuracy and thoroughness rather than speed, hence speed is not something that we actively promote or advertise as a mailfloss advantage. If you are in a rush to get results back, mailfloss probably isn't a good fit. Our focus has been an automatic, set-and-forget real-time email verification with our best-in-class integrations. With that said, we do spend a considerable amount of time and resources on improving speed and scalability and are constantly improving in this aspect. However, given the choice between faster results or more accurate results, mailfloss will err on the side of accuracy. [title] Can you bypass MailChimp's Omnivore? [path] Frequently Asked Questions/ Not always. Omnivore is MailChimp's AI that detects bought or scraped email lists. You shouldn't use these types of lists. Even if you've verified the emails, and even if they are all perfectly valid emails, if they look similar to something Omnivore has seen then you won't be able to upload the list to MailChimp. You're better off not using these lists or finding another email service provider.

Before explaining the five options, make sure you have properly [connected Campaign Monitor](https://docs.mailfloss.com/how-to-connect-campaign-monitor-to-mailfloss) to mailfloss. You only need to do this once and from then on mailfloss will be able to automatically perform email verifications for the connected Campaign Monitor account. Here’s a screenshot of the five options you have with Campaign Monitor email validation: ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/EvU8zW5zsV7pL-g55cekg_1.png) The first option “Manually decide action on bad emails” will display emails deemed invalid so you can decide an action on them, like so: ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/JOHhmbqbBtI0xRzZK46uc_2.png) With manual mode set, you can later decide to delete, unsubscribe, ignore, or report the status as incorrect for all contacts mailfloss determined as invalid. The second option “Unsubscribe bad emails” will unsubscribe the contact from Campaign Monitor. This action is irreversible. You’ll see the contact in Campaign Monitor in the “Unsubscribed” list. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/d3FC9wgtcunvDSmfIwRDC_3.png) The third option “Delete bad emails” is also irreversible.

This is most like boring, traditional email validation services, but is useful if you just want a report of the email verification statuses determined by mailfloss for the connected Campaign Monitor account and nothing more. [title] Email verification Frequency Options [path] Floss options for an email service provider/ Currently, mailfloss has 3 frequency options to determine how often mailfloss will floss your connected email service provider. Below is a brief explanation of each. ### Autofloss If Autofloss is checked, mailfloss will automatically scan your connected email service provider for new subscribers every day and verify them. This is recommended in order to keep your list continually clean and verified. For more detailed information about Autofloss, [check this article](https://docs.mailfloss.com/what-does-autofloss-do). ### Instafloss When turned on, Instafloss will scan and floss every new subscriber in real-time** **with a supported integration. The verification process happens across all lists and the entire account with some exceptions, which can floss based on individual segments or lists. For more detailed information about Instafloss, [check this article](https://docs.mailfloss.com/what-does-instafloss-do). ### Decay Protection With Decay Protection, mailfloss will automatically verify your entire connected email service provider database every month, and prevent existing emails from going stale (on average, emails go stale at a rate of 2.1% per month because of job turnover, abandoned addresses, domains, etc). For more detailed information about Decay Protection, [check this article](https://docs.mailfloss.com/what-does-decay-protection-do). [title] Why can't I register/integrate with my desired email provider? [path] How to connect an email service provider/ **If you're unable to register or integrate a supported email service provider because it’s greyed out or unselectable, the issue is likely tied to your current subscription plan.** Specifically, certain advanced integrations require the Instafloss feature, which is not included in the Lite Plan unless purchased as an add-on. ### Email Service Providers Requiring Instafloss The following email service providers need Instafloss for integration and are unavailable in the Lite Plan: - [MailUp](https://docs.mailfloss.com/how-to-connect-mailup-to-mailfloss) - [Autopilot](https://docs.mailfloss.com/how-to-connect-autopilot-to-mailfloss) - [Customer.io](https://docs.mailfloss.com/how-to-connect-customerio-to-mailfloss) - [Mailigen](https://docs.mailfloss.com/how-to-connect-mailigen-to-mailfloss) - [Remarkety](https://docs.mailfloss.com/how-to-connect-remarkety-to-mailfloss) - [Iterable](https://docs.mailfloss.com/how-to-connect-iterable-to-mailfloss) - [Braze](https://docs.mailfloss.com/how-to-connect-braze-to-mailfloss) To resolve this issue, please refer to [this detailed article](https://docs.mailfloss.com/adding-instafloss-as-an-add-on) for guidance on adding Instafloss as an add-on.

[title] Acceptable bounce rate [path] Get Started/ We know all of the hard work required to obtain a great list of subscribers, and our mission at mailfloss is to help you maintain a healthy and clean list without sacrificing any of them. We consider a healthy bounce rate at 5% or lower, and ideally below 3%, and mailfloss offers a range of options to stay in the healthy bounce rate zone.  Anything in the 7-8% range or above can be considered an unhealthy bounce rate that requires attention. No email verification service can eliminate bounces completely. Please note the only way to 100% truly verify an email address is real with the intended recipient on the other end is to have the recipient respond to a sent email and verify that they are real. No service will be able to get that completely right all of the time, but our Deep Clean engine is one of the best in the industry and we are constantly improving our service with new tests and techniques.  Remember that, in case you have a bounce rate higher than our acceptable rate, we have options our Aggressiveness Options which are designed to allow you to choose how hard you want to floss. As such, you may benefit with Aggressive mode (only **temporarily**) until your bounce rate lowers to acceptable levels. There's a "help me decide" link beside the Aggressiveness options that you can click on to help you decide if Aggressive might be the preferred option until the bounce rate has lowered into the healthy zone. [title] About the Option of Pausing Your Subscription for 3 Months [path] Frequently Asked Questions/ We understand that sometimes you may need to take a break from your subscription. That’s why we offer the option to pause your subscription for up to **3 months**. Below are the details about how pausing works and what to expect. ### How Does Pausing Work? - **Duration of Pause**: You can pause your subscription for a maximum of 3 months. - **Automatic Unpause**: After 3 months, your subscription will automatically reactivate, and billing will resume. :::BlockQuote **Important**: Please set a reminder for when your subscription is set to resume to avoid unexpected charges. ::: - **Returning Earlier**: If you’d like to resume your subscription before the 3-month period ends, simply contact our customer support team. We’ll be happy to assist with reactivating your account. ### What Happens to My Subscription Credits? - **Subscription Credits**: These do not roll over. If your subscription is canceled or paused, any unused credits will be removed. - **Prepaid Credits**: If you’ve purchased prepaid credits, they are not affected by a pause or cancellation. Prepaid credits never expire and can be used anytime. ### How to Pause Your Subscription 1. Log in to your account. 2. Navigate to the **Payments & Plans** section. 3. Under the **Subscription Plan** tab, locate the name of your current plan (e.g., "Current subscription: Monthly Pro"). 4. Click **Cancel** next to your subscription. 5. This will take you to the cancel subscription page. 6. Look for the option "Pause subscription" and select it. **Need Assistance?** If you have further questions or wish to reactivate your subscription sooner, please don’t hesitate to reach out to our **Customer Support** team at hello\@mailfloss.com. We’re here to help! [title] How are you different from X (some email verification services)? [path] Frequently Asked Questions/ We get this question a lot. We created **mailfloss** because email verification is a pain in the butt, and that's where we're different compared to our competitors. We're far easier to use via our integrations—you just set it and forget it with **mailfloss**. Other services, even those that integrate with Infusionsoft, MailChimp, or other email service providers, still require you to remember to use them, go through the results, decide what to do, etc. **mailfloss** is the ONLY email verifier with real-time capabilities for all of our integrations—except for Constant Contact. This means that we provide faster and more seamless service than anyone else in the market. That's really our unique value proposition: **we're the easiest**. **mailfloss** automatically plugs your email marketing from leaking, while the others do not. **mailfloss** is also the only email verifier that automatically fixes commonly misspelled email addresses from popular domains such as Gmail, Yahoo, Hotmail, and AOL. These email addresses would have otherwise been lost, so they can be a significant source of recovered lost revenue if you get these typos a lot. Our favorite customers are the ones who sign up, hook up their integration, set their preferences, and then move on with their lives. Once we've done that, then we know we've succeeded. [title] Does mailfloss detect and handle spam bots? [path] Frequently Asked Questions/ We provide an email verification service to help you keep your lists accurate and free from invalid or risky email addresses. While we protect against spam bots, we can't prevent bots from using real and valid email addresses, which increases the risk of sending emails to unintended recipients. In this situation, implementing additional security measures to prevent them from entering your forms is recommended. To strengthen your form's security and minimize the risk of spam bots, consider the following options: - **Honeypot System: **A honeypot system involves adding a hidden form field that only spam bots would fill out. When this field is detected as filled, the form submission can be automatically rejected as spam. Learn more about this system [here.](https://dev.to/felipperegazio/how-to-create-a-simple-honeypot-to-protect-your-web-forms-from-spammers--25n8) - **Captcha: **Implementing a captcha system adds an extra layer of protection to your forms by requiring users to complete a challenge that only a human can solve. This can effectively block most spam bots from submitting the form. You can find a free alternative [here.](https://www.cloudflare.com/products/turnstile/) - **Risk API: **Detect bad actors & prevent spam signups, taking an email and IP and calculating an associated risk score. This score will help to determine whether a signup is legitimate or not. We suggest an option [here](https://clearbit.com/blog/risk-api-detect-bad-actors-prevent-spam-signups). - **Our Javascript Widget: **Finally, if you want email verification at the very moment an email address is typed into your forms, you can implement the mailfloss javascript widget. Find more information about it [here](https://developers.mailfloss.com/javascript-widget-overview).

The second option “Unsubscribe bad emails” will unsubscribe the contact from Constant Contact. This action is irreversible. You’ll see the contact in Constant Contact in the “Unsubscribed” list. The third option “Delete bad emails” is also irreversible. Once deleted, the contact is gone for good and you won’t find it inside of Constant Contact anymore. The fourth option is a little more advanced and intended for advanced users. It will update custom fields inside of ConstantContact, which you can use to sync with your other databases and CRMs and use in automations.

[title] Get Started [path] / [title] What's a false negative and why is it a risk? [path] Get Started/ ### What is a false negative? We define a false negative as any email address that successfully passes our verification tests during a flossing process but ends up being an address that bounces when an email is sent to it. Our Aggressiveness Options are designed to allow you to choose how aggressively you want to floss. With **Normal** mode, you'll keep more subscribers as we do not run our full gamut of tests, but as a consequence, you may have an increase in false negatives and see them reflected in the bounce rate. We believe this is a sensible option and recommended for most users, as flossing more aggressively will reduce the bounce rate but will also potentially remove more deliverable email addresses than is needed (it may remove too many false positives). Related:  - [What is a false positive](https://docs.mailfloss.com/whats-a-false-positive-and-why-is-it-a-risk) - [Acceptable bounce rate](https://docs.mailfloss.com/acceptable-bounce-rate) In cases of a high bounce rate, you may wish to floss more aggressively. There's a "help me decide" link beside the Aggressiveness options that you can click on to help you decide if Aggressive might be the preferred option until the bounce rate has lowered. Please note that we suggest using Aggressive as a **temporary** measure only, and to ultimately go back to Normal mode once the bounce rate has lowered. ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/SzqTnJXaXMNm7KEno79Kq_1.png" size="62" width="534" height="59" position="center" showCaption="false"} ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/holQ_DU-PtuQOD1p-TrX9_2.png" size="74" width="805" height="808" position="center" showCaption="false"} At the end of the day, our mission at mailfloss is to help you maintain a clean and healthy list, without sacrificing all those hard-earned leads and subscribers. That's why, unless you reach a considerably high bounce rate at 7-8% or above, we recommend keeping Normal mode activated, which is a much more sensible option and allows you to keep the most part of your real subscribers, with fewer [false positives](https://docs.mailfloss.com/whats-a-false-positive-and-why-is-it-a-risk) on your flossing results.

This action is irreversible. The third option, “Delete bad emails”, is also irreversible. Once deleted, the contact is gone for good and you won’t find it inside of Ghost anymore. The fourth option is a little more advanced and intended for advanced users. It will update tags inside Ghost and show them as labels, which you can use to sync with your other databases and CRMs. ![](https://archbee-image-uploads.s3.amazonaws.com/q0k5I8m97LQRRapz7DXqQ-pHTRdV1umtVfqLuftdUTu-20250218-202537.png) For more information about tags [check this article](https://docs.mailfloss.com/what-are-the-custom-fields-and-tags-that-mailfloss-updates-and-which-esps-support-them).

This is due to limitations with the integration's API. This method can be slow and expensive. To enhance your experience and streamline the process, we recommend using a single, Master list for your imports. The current list import process impacts the following integrations: - Benchmark - Braze - Campaign Monitor - Iterable - Mailchimp - Mailigen - MailUp - Moosend - Sendlane - Sendloop - SendPulse If you use one of these integrations, we recommend using a Master list of all the contacts you want flossed. It will be significantly faster and reduce potential errors with duplicates and credits. ### How to select and floss your master list Here’s a brief guide on how to select and floss your master list. For a complete explanation of how to floss specific lists, you can find a guide [here](https://docs.mailfloss.com/how-to-floss-only-a-specific-email-listsegmenttag). **1.Click the "Start scan & floss" button.** ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/iThC4D-IeHvXTsPvXXbjL_1.png) **2. Make sure you have enough credits to cover your list and select the corresponding option.** ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/qoCnyV6d1EOMnXYWAeevH_2.png) **3. Select your master list from the dropdown menu and click the "Yes, I'm sure!" button to start your process.** ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/WYowv4Y2XqAyKEaaEBdPr_4.png) By adopting the practice of using a single, Master list, you can significantly improve the efficiency, speed, and cost-effectiveness of your email verification process. We encourage you to implement this method and experience the benefits firsthand!

When using our service, there are some risks that can arise with the results. These risks can amplify when employing auto-actions with a supported ESP. These risks include: ### 1. Bounced email addresses that can still receive emails Our system may mark an email address as bounced. This is because it has bounced in the past and potentially can again in the future. It does not always mean that a bounced email address cannot still receive emails going forward. ### 2. Non-disposable addresses labeled as disposable Our system may categorize an email address as disposable, which typically refers to temporary or throwaway addresses. In some instances, non-disposable addresses may be inaccurately flagged. There are protections in place to minimize this from happening. ### 3. Legitimate addresses marked as spam While our system is designed to identify spam-related email addresses, there can be cases where legitimate addresses had a bad campaign and got marked as spam, even if these addresses are well-intentioned and follow best practices. ### 4. Accept\_all addresses that deliver Accept\_all addresses are those that look good, but any email address at this domain looks good and cannot be verified completely. These addresses may or may not bounce, depending on the mail server of these domains and how it is configured. ### 5. Unverified addresses that are fine There may be instances where an email address is marked as unverified because of various factors including the server took too long to respond, grey listings, and various other technical errors. ### 6. False positives and false negatives We have detailed articles about [false positives](https://docs.mailfloss.com/whats-a-false-positive-and-why-is-it-a-risk) and [false negatives](https://docs.mailfloss.com/whats-a-false-negative-and-why-is-it-a-risk) to help you understand them better and how they may affect your bounce rate. It's important to understand these risks with email verification, and mailfloss strives for the highest accuracy. We continuously improve our algorithms to minimize false classifications and our Deep Clean engine is constantly improving.  ### 7. DNS errors causing misclassification of email addresses As rare as this error can be, a sudden DNS issue can lead to legitimate email addresses being marked as "illegit" by mistake after our verification process ends. Our team is always working to detect and solve this and other similar kinds of issues in time in case they happen. # Risk mitigation strategies ### 1. Set your aggressiveness option Choose and set your preferred aggressiveness option to determine how aggressive mailfloss will perform email verification. For more information about our aggressiveness options, [check this article](https://docs.mailfloss.com/email-verification-aggressiveness-options). ### 2. Whitelist/Blacklist options Get a better control in terms of what mailfloss cleans and does not clean by adding addresses or domains to your whitelist or blacklist. For more information about this process, [check this article](https://docs.mailfloss.com/add-your-blacklistwhitelist-options). ### 3. Use the Category Exclusions option There are some categories that you might not want automatically removed, and that's what category exclusions are for. You can exclude certain categories from those that you want automatically removed, and then you can manually review them and decide what to do with them within our dashboard. For more information about how to set your category exclusions, [check this article](https://docs.mailfloss.com/what-do-category-exclusions-do). If you have any questions about the mentioned risks or mitigation strategies, our support team is ready to assist you. Feel free to reach out if you have any questions or concerns. [title] Category Definitions [path] Get Started/ Below is a comprehensive list of the categories mailfloss uses to classify email addresses during verification. ## Invalid Email addresses that fail syntax checks and are deemed invalid. ## Spam Email addresses flagged as potential spam accounts. ## Role Addresses associated with roles (e.g., "administrator"). While these emails may be valid, they often underperform and can negatively impact deliverability rates. ## Banned Email addresses containing banned keywords or domains, such as offensive language or patterns associated with fake or poor-quality addresses. ## Disposable Temporary email addresses provided by disposable email services. These are unreliable and negatively affect deliverability. ## Illegitimate Addresses associated with domains lacking valid MX records, making them incapable of receiving emails. These are marked as "illegit" in reports. ## Available Email addresses linked to inactive domains or domains listed as parked or for sale. Such addresses are typically invalid. ## Unverified Addresses that appear valid but cannot be fully verified due to non-responsive domains. ## Blacklisted Email addresses flagged for containing user-defined blacklisted keywords. ## Bounced Addresses that have previously resulted in email bounces, making them risky to use. ## Complained Addresses that have reported emails as spam in the past, indicating a higher likelihood of future complaints. ## Nonexistent Addresses determined to be non-existent through testing. ## Deactivated Addresses that have been deactivated and can no longer receive incoming emails. ## Inbox Full Addresses unable to receive emails because the recipient's inbox is over quota. ## Failed Exchange Addresses that fail Microsoft Exchange testing and pose a high risk of hard bounces. Sending emails in bulk to these addresses is not advised. ## Accept All Domains configured to accept all emails appear valid but cannot be fully verified. For example, a domain like **mailfloss.com** might validate both **martin\@mailfloss.com** and **fakeaddress\@mailfloss.com**. Since such domains do not confirm individual addresses, these are flagged as "accept\_all" in reports. ## Skipped Verification was skipped for this address, often because the user's plan limits have been reached. ### Note We’re constantly improving our verification processes and algorithms. If you believe an email has been miscategorized, please reach out to us. For manual verifications, you can report errors by clicking the “Report as Incorrect” button. [title] Passkeys: A Faster and More Secure Way to Sign In to mailfloss [path] Get Started/ mailfloss now supports **passkeys**, giving you a faster and more secure way to sign in to your account without having to enter your password. A passkey can use the security features already built into your device, such as **Windows Hello, Touch ID, Face ID, or your device's PIN**. For example, if you're using a Windows computer, you can sign in to mailfloss using your Windows passkey. ## What is a passkey? A passkey is a passwordless sign-in method that uses your device's built-in security to verify your identity. Unlike a password, a passkey is not something you need to remember or type. Your device securely stores the passkey, and you use your device's authentication method to sign in. Passkeys can help make signing in both easier and more secure. ## How to create a passkey in mailfloss You can create a passkey directly from your mailfloss account: 1. Log in to your **mailfloss** account. 2. Go to **Account Settings**. 3. Open the **Pass Keys** tab. 4. Select the option to create a new passkey. 5. Follow the instructions provided by your device or browser to complete the setup. Once your passkey has been created, you can use it to sign in to mailfloss without entering your password. ### Using a Windows passkey If you're using Windows, you may be prompted to authenticate using **Windows Hello**, such as your PIN, fingerprint, or facial recognition, depending on your device. Other devices and browsers may offer different authentication methods, such as Touch ID or Face ID. ## Managing your passkeys You can view and manage the passkeys associated with your mailfloss account from: **Account Settings → Pass Keys** We recommend giving each passkey a recognizable name so you can easily identify it later. If you have any questions or run into trouble setting up a passkey, feel free to reach out to our support team. [title] Frequent Questions [path] / [title] Are duplicate email addresses removed? [path] Frequently Asked Questions/ Yes, during flossing one of the first steps mailfloss will do is to remove any duplicate email addresses from flossing as part of the flossing process (deduplication). Duplicate email addresses are not charged additional credits. The report returned after flossing will have the duplicates removed, so it may have less email addresses in it than the number of email addresses uploaded. [title] How to Update Your Account Information [path] Frequently Asked Questions/ If you need to update your personal or business information on mailfloss, it’s easy to do it directly from your account! ### You can change the following details: - **Name** - **Phone Number** - **Organization** - **Email Address** - **Country** - **Address** - **City** - **State** - **Postal Code** ### How to Update Your Information: 1. Log in to your mailfloss account. 2. Go to **Account Settings**. 3. Update the fields you wish to change. 4. Click **Save** to confirm the changes. ### Important Note About Changing Your Email Address: After updating and saving your new email address, you’ll need to verify it. You’ll see an option to **send a verification email** right above the email field. Click that link to receive a confirmation email and complete the update. ### Need Help? If you run into any issues or would prefer that we make the changes for you, feel free to contact our support team at [hello@mailfloss.com](#). We're happy to assist! [title] What's the difference between Autofloss and Instafloss and what are the pros and cons of each? [path] Frequently Asked Questions/ Autofloss and Instafloss are both features of mailfloss that verify (floss) new subscribers. There are some differences that this article aims to highlight. 1. Autofloss is available on all subscription plans, whereas Instafloss is not available on the Lite plan by default, but is available as a Lite plan add-on. 2. Autofloss checks new subscribers from the previous day and runs daily. Instafloss checks in real-time. 3. Autofloss is available on all email service providers (ESPs) except Customer.io, Mailigen, Remarkety, Braze, Iterable, ClickFunnels, Encharge, and Beehiiv. Instafloss is not available for Constant Contact. 4. For some ESPs, Autofloss has the ability to selectively check specific lists or tags. With Instafloss, verification happens across all lists and the entire account with some exceptions. 5. Autofloss pulls subscribers from the connected ESP, and is more certain to gather all of the subscribers. Instafloss, especially from some ESPs, is retrieved on a best-effort basis and is not guaranteed to run for every single new subscriber. **For HubSpot specifically, Instafloss intentionally skips contacts that are added via bulk imports, so Autofloss should be relied on to verify those contacts.** Based on our tests, Instafloss successfully receives about 99% of new contacts. 6. For reporting, Autofloss will display in the dashboard for each floss it runs. With Instafloss, all the flosses are aggregated from the previous day and will show up as one session in the dashboard. 7. With some ESPs, using Autofloss there may be redundant or duplicate contacts from previous days' floss. With Instafloss, there is less redundancy but may still be some as some ESPs will send the contact over in quick succession sometimes. 8. For some ESPs including MailUp, Gist, Campaigner, Remarkety, AWeber, DailyStory, Wishpond, Moosend, Sendlane, Braze, Iterable, Customer.io, Klaviyo, and GetResponse, there are additional steps required to setup Instafloss. So should you use Autofloss or Instafloss? If you had to pick one, use Instafloss since you can verify, fix, update, or remove the contact in real-time. Otherwise, if real-time isn't needed or if you have Manual Mode turned on, choose Autofloss.

Before explaining the four options, make sure you have properly [connected Keap](https://docs.mailfloss.com/how-to-connect-keap-formerly-infusionsoft-to-mailfloss) to mailfloss. You only need to do this once and from then on mailfloss will be able to automatically perform email verifications for the connected Keap account. Here's a screenshot of the five options you have with Keap email validation: ![](https://archbee-image-uploads.s3.amazonaws.com/q0k5I8m97LQRRapz7DXqQ-kdlopiRxV-v5xWmx3x1-V-20250227-185703.png) The first option "Manually decide action on bad emails" will display emails deemed invalid so you can decide an action on them, like so: ![](https://archbee-image-uploads.s3.amazonaws.com/q0k5I8m97LQRRapz7DXqQ-gAtKwIBe542vjNBhFziKo-20250227-185724.png) With manual mode set, you can later decide to delete, unsubscribe, ignore, or report the status as incorrect for all contacts mailfloss determined as invalid. The second option "Unsubscribe bad emails" will unsubscribe the contact from Infusionsoft. This action is irreversible. You'll see the contact in Infusionsoft as "Status: Opt-Out: Admin". ![](https://mailfloss.com/wp-content/uploads/2018/03/infusionsoft-unsubscribed-contact-status-1024x1010.png) The third option "Delete bad emails" is also irreversible. Once deleted, the contact is gone for good and you won't find it inside of Infusionsoft anymore. The fourth option is a little more advanced and intended for advanced users. It will update custom fields inside of Infusionsoft, which you can use to sync with your other databases and CRMs and use in automations. This action is also irreversible. For finding this information, go to "Contact information" and click on the "Custom Fields" tab.  If you need more information about our custom fields [check this article](https://docs.mailfloss.com/what-are-the-custom-fields-and-tags-that-mailfloss-updates-and-which-esps-support-them). ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/UyW5RGQ4ZXncBz1y8JoU2_4.png" size="76" width="542" height="461" position="center" showCaption="false"} The final option is "do nothing". Basically, all this option does is send you an email report of the latest floss session, but doesn't actually change anything inside of Infusionsoft or mailfloss. This is most like boring, traditional email validation services, but is useful if you just want a report of the email verification statuses determined by mailfloss for the connected Infusionsoft account and nothing more. [title] Encharge email verification options using mailfloss [path] Floss options for an email service provider/ If you’re using mailfloss for Encharge email verification, you have five options at your disposal.

[title] Add your blacklist/whitelist options [path] Floss options for an email service provider/ mailfloss has a good set of defaults in terms of what it cleans and does not clean. However, if you are looking for more find-grained controls then you can go ahead and add your blacklist and whitelist options [here](https://app.mailfloss.com/integrations?utm_source=drip\&utm_medium=email\&utm_campaign=add-your-blacklist-whitelist-options). Select your integration, click "Show more options", and click on the link "whitelist/blacklist".  ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/0FaD0Zlumibu1XqfqvQvx_1.png" size="28" width="214" height="317" position="center" showCaption="false"} ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/okqPofKc9xOlkKqpzP3F9_2.png" size="30" width="209" height="265" position="center" showCaption="false"} ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/x0mjwBF0tTnw4mgHT6cr6_3.png) From there, if you want to whitelist an email address as an example, uncheck Local Part and check Email. Or if you want to whitelist an entire domain, uncheck Local Part and check Domain. Then enter the email address or domain into the input and press enter. Each new entry added to the whitelist can have different settings. You can check these settings by **hovering** **over** the entry. If you need to change the values of any entry, you can hover over it and remove it by clicking the **"X"** that appears next to the name. Then, you can add it again with the desired options selected. ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/M64qlA6Yj7UAzO0jKdCkk-15v2t26Lek9EK7yxWHfvY-20250331-184043.png" size="70" width="593" height="307" position="center" showCaption="false"} ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/M64qlA6Yj7UAzO0jKdCkk-xM6_KQGMpQpsn-HLwOa4W-20250331-184139.png" size="60" width="576" height="328" position="center" showCaption="false"} **Blacklist:** The blacklist is used to block specific keywords, domains, or patterns in email addresses that you *don’t want to verify*. Contacts on the blacklist will **always fail verification** and, depending on your settings, may be **automatically unsubscribed or deleted**. This is typically used for things like swear words, disposable domains, or problematic addresses. **Whitelist:** The whitelist allows you to **bypass filtering** for specific keywords, domains, or email patterns you *want to keep*, even if they might normally fail verification. Whitelisted contacts will still be verified, but they **won’t be unsubscribed or deleted**, regardless of their result. This is useful for role-based emails (e.g., info@, admin@) or trusted addresses you always want to retain. **Note: **Blacklisted and whitelisted contacts **still consume credits **when verified. These settings only affect how the contacts are handled *after *verification, not whether they are processed. [title] What are the custom fields and tags that mailfloss updates and which ESPs support them? [path] Floss options for an email service provider/ mailfloss will update custom fields or tags for our supported ESPs. Unless otherwise stated, ESP tags and custom fields are created for you automatically. Unless otherwise stated, ESPs utilize custom fields for updates rather than tags. For tag updates, we support Infusionsoft, Gist, and Sendlane. The custom fields properties and tags we sync to your ESP are:  1. name: "mf\_validation\_passed", label: "mailfloss validation passed", description: "False, if the email failed mailfloss validation." 2. name: "mf\_reason", label: "mailfloss reason", description: "The reason mailfloss failed this email." 3. name: "mf\_mode", label: "mailfloss mode", description: "Normal, Aggressive, or Custom floss mode." 4. name: "mf\_flossed\_on", label: "mailfloss flossed\_on", description: "The date mailfloss validated this email." 5. name: "mf\_status", label: "mailfloss status", description: "The status of this email. It can be 'undeliverable', 'risky', or 'unknown'." 6. name: "mf\_fixed", label: "mailfloss fixed", description: "Set to true if the email address typo was fixed successfully." 7. name: "mf\_suggestion", label: "mailfloss suggestion", description: "A potential suggested email address, if one exists." Now you can use this data to sync your ESP with your other CRM systems by looking up the contact and looking for the mf\_validation\_passed property. Any marked false by mailfloss you can now update in your other CRMs, run automations and create reports. Note that mailfloss only updates a contact with custom fields if the contact failed mailfloss validation. Here are the tags we use for Ghost and GoHighLevel. Infusionsoft, Gist, and Sendlane used these tags prior to switching to custom fields. "mf\_failed - invalid", "mf\_failed - spam", "mf\_failed - role", "mf\_failed - banned", "mf\_failed - disposable", "mf\_failed - illegitimate", "mf\_failed - available", "mf\_failed - unverified", "mf\_failed - blacklisted", "mf\_failed - bounced", "mf\_failed - complained", "mf\_failed - accept\_all", "mf\_failed - nonexistent", "mf\_failed - deactivated", "mf\_failed - inbox\_full", "mf\_status - undeliverable", "mf\_status - risky", "mf\_status - unknown", "mf\_fixed - true", "mf\_suggestion - true" [title] Understanding Prepaid Credits [path] Plans and Pricing/ Prepaid credits offer flexibility and convenience for email verification needs. Unlike subscription credits, prepaid credits can be purchased independently, allowing you to use them even with a free account. The key advantage of prepaid credits is their lack of expiration date, meaning you can use them at your own pace. ## How to Purchase Prepaid Credits 1. Log in to your app account. 2. Navigate to the **Payments & Plans** section in the navigation bar. 3. Select the tab for **Prepaid Credits**. 4. Choose the desired amount and proceed with your purchase. With prepaid credits, you have the freedom to verify email addresses whenever it suits you, ensuring smooth and efficient verification processes without the pressure of time constraints. ## Prepaid Credits Pricing One credit equals one email address. For the most up-to-date pricing, please visit our official pricing page: [mailfloss Pricing](https://docs.mailfloss.com/pricings-for-subscription-plans-subscription-add-ons-and-prepaid-credits). [title] What is Auto-refill and how does it work? [path] Plans and Pricing/ What happens if you run out of credits and need to continue with your flossing work? We have options at your disposal, such as Auto-refill. Auto-refill works by automatically purchasing prepaid credits when your credits fall below a certain threshold. So, for example, you could set it so that it automatically purchases 50000 credits when the credits fall below 12500. This way, you can keep better control of your purchases and the amount of your credits as well. You can activate Auto-refill by going to "Payments and Plans", and selecting the "Auto-refill credits" tab. Check the "Enable auto-refill" box. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/QNiSJpOv8xFPKM3ko1yeL_1.png) Select how many credits you want to buy per auto-refill by clicking on the "Automatically buy prepaid credits" dropdown selection. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/ovMaVBQJ81W7kYjexbYZT_2.png) And then, establish the credit balance threshold to do so on the "When prepaid credits balance falls below" dropdown. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/ZVRzKSHH-RtDnn5C6JIWS_3.png) Once you've finished, click the Save button, and you're done! ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/M7KOKqTxYaFu_dEd57ea9_4.png) [title] Can I Change The Invoice Email Address? [path] Troubleshooting/ At this time, we do not have the ability to update the email address for receiving invoices directly within the app. However, you can easily set up a filter in your email inbox to automatically forward invoices to your desired email address. ### Steps to Set Up Email Forwarding 1. **Log In to Your Email Account** - Open the email service you use to receive invoices (e.g., Gmail, Outlook, etc.). 2. **Create a Filter for Invoice Emails** - Look for an option to create filters or rules in your email settings. - Set the filter criteria to match emails: - **Sender**: hello\@mailfloss.com - **Subject**: mailfloss payment receipt 3. **Set Up Forwarding** - In the filter settings, select the option to **forward emails** that match the criteria. - Enter the email address of your accounting department or desired recipient. 4. **Save and Test** - Save the filter or rule, then send a test email (or wait for the next invoice) to ensure the forwarding works correctly. If you have any questions or need further clarification, please don't hesitate to reach out to our support team. We're here to assist you every step of the way!

From there you should see a list of lists/segments from your integration, as well as a search bar and refresh button. Click the "Refresh" button to get the latest lists/segments, use the search bar to find the list/segment you wish to floss, and then click the "Import" button beside to begin the flossing process.

There is a fee associated with each additional email verified. Overage is turned off by default. You can turn it on by unchecking the "stop after credits exhausted" option in your account settings. However, *overage fees can get pretty expensive*, so we don't really recommend this as a solution. Pro plan subscribers get overage at $0.001 per email verified, $0.003 for Business, and $0.005 for Lite plan subscribers. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/Noysy68gVd930_f0JEbEC_734774c1-3846-43f7-961c-f32184fa55b7.png) An alternative option would be to use the auto-refill credits feature. Auto-refill works by automatically purchasing prepaid credits when your credits fall below a certain threshold. So, for example, you could set it so that it automatically purchases 50000 credits when the credits fall below 12500. This way, you can keep better control of your purchases and the amount of your credits as well. [title] How to add a credit card [path] Plans and Pricing/ To add a credit card, go to "Payments & Plans" and click the "Credit cards" tab. From there, click the "Add credit card" button and enter your credit card details and click to save. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/xuwhGuQyoj7BXUbwtb8aM_2af50873-97f1-4ad0-8734-e940c7e9c43e.png) [title] How to Request a Manual Invoice [path] Plans and Pricing/ **For Prepaid Credit Purchases:** If you wish to purchase prepaid credits without adding a credit card to your account, we're happy to accommodate. Please send us a ticket specifying the amount of credits you're trying to purchase and the billing details that you need us to include in your invoice. Once you've made this request, our team will review it promptly and send you an invoice, allowing you to complete the payment through the online invoice link. **For Subscription Payments:** Currently, manual invoices are primarily available for prepaid credit purchases. For subscription payments, our automated system handles the billing process. However, if you encounter challenges with credit card payments and need assistance, please reach out to our support team. Please note that while we strive to assist our customers, manual invoices for subscription payments are subject to review, and we may not always be able to accommodate this request. [title] Which subscription plan should I choose? [path] Plans and Pricing/ To find a plan suitable to you, it helps to answer the following two questions: 1. How many total subscribers do you currently have? If you want to use our Decay Protection feature, you'll need to ensure your plan covers the total subscribers. If it doesn't, you will need to purchase additional prepaid credits or turn on overage. 2. How many new subscribers do you get daily, on average? This is important to know since Autofloss will clean new subscribers daily. You'll want to ensure your plan covers this daily average for the entire month. Also, note that subscription plans are only applicable if you use a supported email service provider. If you have additional questions, please get in touch. We'd be happy to help you find the plan that works best for you. [title] Where do I find invoices? [path] Plans and Pricing/ Visit the Payments & Plans section by clicking it in the navigation bar. From there click on "Receipts & billing history" and from there you'll be able to access the billing history. [title] How do I add more features to my subscription? [path] Plans and Pricing/ If there's a feature you'd like that isn't in your plan, you have the option of adding it to your subscription via our subscription add-ons. If you are subscribed to a plan you will see an add-ons tab under "Payments & Plans" where you can manage add-ons. With add-ons, you can: - add more subscription credits to your subscription - add additional ESP integration connections - add the category exclusions for the Auto-actions feature - add the Typo Fixer feature - add the ability to Auto-update custom fields and tags - add webhook notifications ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/anYKgnFPTML76hFHaGDHv_add-ons.png) [title] How do I cancel my subscription? [path] Plans and Pricing/ To cancel, please visit the [plans](https://app.mailfloss.com/plans) section inside of the mailfloss app and click the cancel link.

[title] Brevo email verification options [path] Floss options for an email service provider/ If you’re using mailfloss for Brevo (formerly Sendinblue) email verification, you have five options at your disposal. Before explaining the five options, make sure you have properly [connected Brevo](https://docs.mailfloss.com/how-to-connect-brevo-to-mailfloss) to mailfloss. You only need to do this once and from then on mailfloss will be able to automatically perform email verifications for the connected account. Here’s a screenshot of the five options you have with Brevo email validation: ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/Tb6JyxP8jjZJbjCxUBWwD_1.png) The first option “Manually decide action on invalid emails” will display emails deemed invalid so you can decide an action on them, like so: ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/alfiZ_3rg7x2nHeiYq2o1_2.png) With manual mode set, you can later decide to delete, unsubscribe, ignore, or report the status as incorrect for all contacts mailfloss determined as invalid. The second option, “Auto-unsubscribe invalid emails”, will unsubscribe the contact from Brevo and remove the contact from the lists it belongs to. This action is irreversible. The third option, “Auto-delete invalid emails”, is also irreversible. Once deleted, the contact is gone from the lists it belongs to inside Brevo. The fourth option is a little more advanced and intended for advanced users. It will update custom fields inside of Brevo, which you can use to sync with your other databases and CRMs. For more information about our custom fields [check this article](https://docs.mailfloss.com/what-are-the-custom-fields-and-tags-that-mailfloss-updates-and-which-esps-support-them). The final option is “do nothing”. Basically, all this option does is send you an email report of the latest floss session, but doesn’t actually change anything inside of Brevo or mailfloss. This is most like boring, traditional email validation services, but is useful if you just want a report of the email verification statuses determined by mailfloss for the connected Brevo account and nothing more.

[path] Plans and Pricing/ There are five ways to add more credits to your account: 1. Purchase more prepaid credits. These credits do not expire. You can purchase more credits 2. Upgrade your subscription plan. If you need more credits on a monthly basis, you can upgrade your subscription. You can do that 3. Add subscription add-on credits. These are subscription credits that will be added to your existing subscription. This is a flexible option that allows you to add credits at different packages and quantities. 4. Use the auto-refill feature to automatically add prepaid credits when falling below a threshold. You can set up auto-refill 5. Turn on overage. We don't recommend this setting as the fees can be substantial. **Remember that one credit equals one email address.** [title] Can I send billing receipts to a different email address? [path] Plans and Pricing/ At this time, billing receipts can only be sent to the email address associated with your account. It is not possible to send receipts directly to a different email address. ## Workaround If you'd like to receive receipts at a different email address, you can set up automatic email forwarding from your account email to your preferred email address. Once configured, all future billing receipts will be forwarded automatically. [title] Issues with Zoho CRM [path] Troubleshooting/ Please be aware that this tool is not an official product developed by mailfloss. It has been created by a third-party developer. Unfortunately, we aren't able to provide support as we only provide the API and did not develop this extension. For support related to the Zoho CRM integration, we kindly ask you to reach out to the developers directly through their vendor page here - [https://marketplace.zoho.com/vendor/nexivo-zoho-premium-partner](https://marketplace.zoho.com/vendor/nexivo-zoho-premium-partner) Please be advised that while you may need to contact the developers for technical assistance, it's important to ensure that you have an active mailfloss account, an API key, and available credits within our application to enable the smooth functioning of the extension. If you have any further questions or need assistance with your mailfloss account, please don't hesitate to reach out to our support team. We're here to help! [title] I exported my emails from my email service provider and uploaded it to mailfloss. Will it sync back to the ESP? [path] Troubleshooting/ No. mailfloss has no way of knowing that the emails came from your ESP. There's most certainly a better way to do this with mailfloss. mailfloss was designed so you would not have to do any file exporting and importing from/to your ESP. Under your integration inside of mailfloss, click "Show more options" and then click "advanced". You should see either lists or tags there. It is better to either group your contacts into these lists or tag the contacts and then do an import form mailfloss.  This will ensure any actions you want to do from mailfloss will be applied to your contacts from the connected ESP. If you have any questions on best how to do this, please contact us. But if your first thought is to export a file and upload it, that's most certainly not the "mailfloss way". [title] I didn't receive my verification email, what do I do? [path] Troubleshooting/ Please check your junk folder for the verification email. If it isn't there, it is likely your email filters prevented delivery to your inbox. If that's the case, you are welcome to contact us so that we may manually verify your email address. You are also able to proceed with mailfloss by going to [https://app.mailfloss.com/](https://app.mailfloss.com/) The next time you log in, you can also choose the passwordless login option, which will also automatically verify your email address after you log in. [title] High bounce rate after flossing [path] Troubleshooting/ If you're getting a bounce rate 10% or higher after using mailfloss something is wrong. ### If using an integration The first thing to check is the **aggressiveness setting**. If it's set to a **Custom floss setting**, you may be excluding some crucial tests, which could lead to a higher bounce rate. You may want to use the Normal setting or even Aggressive, instead. To determine the best setting for your needs, click the **"Help me decide"** link beside the "Aggressiveness options" in the app. You can also [read more about aggressiveness settings here](https://docs.mailfloss.com/email-verification-aggressiveness-options). The second thing to check is if you have Manual Mode turned on. If you do, have you looked in the integrations page to see if there are any invalid email addresses? These will accumulate in the integrations page under your connected integration if left unattended. If you have Manual Mode turned on, the invalid email addresses are not automatically removed. You will need to visit the integrations tab and manually remove the email addresses yourself. ### If using the file upload or copy and paste methods If you've exported the mailfloss floss report and uploaded the results to your email service provider directly, make sure you are using only email addresses that have passed and not the email addresses that haven't. This is a fairly common mistake as the result report contains both failed and passed addresses. You can read more about the status and category definitions [here](https://docs.mailfloss.com/status-definitions) and [here](https://docs.mailfloss.com/category-definitions). ### Other things to consider There are many reasons an email address can bounce, and mailfloss helps reduce this by identifying email addresses that are invalid. But an invalid email address is not the only reason an email address bounces. The easiest way to see the reason an email address bounced is to look at the bounce report. The bounce report should have indicators like the bounce message and bounce reason. Some of the reasons that are not related to invalid email addresses include: - DMARC is incorrectly configured - Blocked due to policy - Rejected by spam filter - Soft bounce due to technical errors If contacting us about high bounce rates, please include the bounce report in the support ticket. This is critical for us to help you figure out what might be happening. Most email service providers consider 7-8% or more as a high bounce rate, and when many email service providers will start issuing warnings and banning accounts. We try to get the bounce rate below 5% to keep you in the safe zone, and ideally below 3%. Please note the only way to 100% truly verify an email address is real with the intended recipient on the other end is to have the recipient respond to a sent email and verify that they are real. No service will be able to get that completely right all of the time, but we try our best and are constantly improving our service with new tests and techniques. [title] Flossing is slow or stuck [path] Troubleshooting/ Various factors such as our load, the makeup of the email addresses uploaded, global network activity, and so on can affect how long a floss session will take to finish, but cleaning will always finish.  Our Deep Clean engine may take extra time as it does additional pass-thru and tests on harder-to-verify email addresses and domains. Sometimes near the end, a session may look stuck at 99% as well. This is our anti-greylisting technology at work to ensure we can verify additional email addresses, as well as our Deep Clean engine double-checking harder-to-verify domains to ensure more accurate results. If you feel a floss session is really stuck please contact us so we can investigate. [title] Need Help? Here's How to Contact Us [path] Troubleshooting/ We’re here to assist you!

[path] Troubleshooting/ When verifying a list of emails, our system efficiently handles duplicate entries to ensure accuracy and conserve your verification credits. If you upload a list with duplicate emails, the system will only verify each unique email once. For example, if you upload a list of 10000 emails and 6 of them are duplicates, you will receive verification results for 9994 emails. The credits used will correspond to the number of unique emails verified. In the example above, with 9994 unique emails, only 9994 credits will be used. To ensure you get the most accurate results and avoid any confusion, please make sure your email list does not contain duplicate emails before uploading. If you have any questions or need further assistance, please contact our support team. We're here to help! [title] Flossing stopped working, not flossing, not verifying, or didn't floss all emails [path] Troubleshooting/ If flossing stopped working, is not flossing, not verifying, or taking a long time, please don't hesitate to reach out to us. Flossing and importing can take a long time depending on the number of email addresses, but sometimes there could be quirks or bugs that are preventing flossing or importing from completing. If an integration was working and stopped suddenly, check if you have Autofloss enabled. If it is enabled but you aren't receiving email reports, please ensure you have enabled receiving email reports under [settings](https://app.mailfloss.com/settings). If it isn't any of those reasons then please use the Contact Us tab to let us know so we can look into this for you. [title] [Action Option] Manually decide action on invalid emails [path] Floss options for an email service provider/ The first option “Manually decide action on invalid emails” will display emails deemed invalid so you can decide an action on them.  With Manual Mode set, you can later decide to update custom fields, unsubscribe, delete, ignore, or report the status as incorrect for all contacts mailfloss flagged during flossing based on the Aggressiveness Options set at the time of flossing. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/Ezb3K171Qjlxf0_nkcYgb_243c44b7-99cf-4ceb-b943-45de8cd3e7f9.png) Every button does pretty much what its name says. **Unsubscribe:** Unsubscribe all the selected addresses from the email list. **Delete:** Deletes permanently all the selected addresses. **Update custom fields:** Advanced option. Updates the custom fields on the selected addresses showing when and why that action was performed. **Filter:** Shows addresses by selected reason. Remember that it only works with the Reason column. **Report incorrect:** If there's a certain address marked as failed, but you feel the result is incorrect, it can be reported to us. **Ignore:** Just ignore the status of all the selected addresses. This will remove the email addresses from the Manual Mode list, but not do anything else. **All integrations that have this action option:** - ActiveCampaign - ActiveTrail - AWeber - Beehiive - Benchmark - Braze - Brevo - Campaign Monitor - Campaigner - ClickFunnels - Constant Contact - Kit - Customer.io - DailyStory - Drip - Emma - Encharge - GetResponse - Ghost - Gist - GoHighLevel - Hubspot - iContact - Keap - Intercom - Iterable - Klaviyo - MailChimp - MailerLite - Mailigen - MailUp - Mautic - Moosend - Ontraport - Remarkety - Sendlane - SendPulse - VerticalResponse - Wishpond - Autopilot [title] VerticalResponse email verification options [path] Floss options for an email service provider/ If you’re using mailfloss for VerticalResponse email verification, you have five options at your disposal.

Here's what you need to know about subscription credits: - Subscription credits reset on your billing day, giving you a fresh set of credits to use for the upcoming month. - The number of credits you receive depends on your subscription plan level. - Subscription credits do not accumulate or "roll over" from one month to the next, encouraging consistent usage and ensuring you always have access to the latest verification capabilities. To purchase a subscription and unlock subscription credits: 1. Start a 7-day free trial from our pricing page. 2. If you already have an account, log in and navigate to Payments & Plans in the navigation bar. 3. Select the subscription tab and make your purchase accordingly. Subscription credits provide a reliable and consistent solution for your email verification needs, ensuring seamless verification processes month after month. **Remember that one credit equals one email address.** [title] Yahoo and Hotmail detection limitations [path] Troubleshooting/ Yahoo, Hotmail, and other free email providers are notoriously difficult to detect and also deliver to. Only a few email verification providers can accurately detect Yahoo-owned email addresses. These include Yahoo, AOL, and Verizon domains.  mailfloss' Deep Clean engine is one of the few email verification services that can detect these and won't simply mark them as Accept All as most services incorrectly do. However, mailfloss cannot detect Yahoo-owned email addresses that are disabled. mailfloss can only detect that the addresses exist and if it has been deactivated, but if Yahoo disables an email address due to inactivity we aren't able to detect these. The bounce reason looks like this: "554 30 Sorry, your message to *email\@yahoo.com* cannot be delivered. This mailbox is disabled (554.30)." This is normally not an issue except for old lists. If a list is old, please be aware of this limitation and recognize that it might be better to quarantine Yahoo email addresses from your main campaigns. We can detect deactivated Yahoo addresses, whose bounce code looks like the following: "552 1 Requested mail action aborted, mailbox not found" It's not entirely clear how Yahoo distinguishes a disabled address versus and deactivated address, however, there has been an uptick in Yahoo disabled addresses as the company has restructured in recent years. [title] Sendpulse email verification options [path] Floss options for an email service provider/ If you’re using mailfloss for Sendpulse email verification, you have five options at your disposal.

You only need to do this once and from then on mailfloss will be able to automatically perform email verification for the connected Sendpulse account. Here’s a screenshot of the five options you have with Sendpulse email validation: ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/piMmlCiNrgwOIEN2NJQ5m_1.png) The first option “Manually decide action on invalid emails” will display emails deemed invalid so you can decide an action on them, like so: ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/MDARfmag-6FUsE4g6vQa4_2.png) With manual mode set, you can later decide to update custom fields, unsubscribe, delete, ignore, or report the status as incorrect for all contacts mailfloss determined as invalid. The second option “Unsubscribe invalid emails” will unsubscribe the contact from Sendpulse. This action is irreversible. You’ll see the contact in Sendpulse with a red icon and the status of "Unsubscribed from all emails". ::Image[]{src="https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/LoaQ4qVRiwEuqt6YDi7OW_3.jpg" size="48" width="246" height="81" position="center" showCaption="false"} The third option “Auto-delete invalid emails” is also irreversible. Once deleted, the contact is gone for good and you won’t find it inside of Sendpulse anymore. The fourth option is a little more advanced and intended for advanced users.

The third option “Delete bad emails” is also irreversible. Once deleted, the contact is gone for good and you won’t find it inside of Sendlane anymore. The fourth option is a little more advanced, and intended for advanced users.

Automatically update invalid emails, indicating when it was flossed and why it was marked as bad.  We consider this an advanced option since you need to have knowledge of how the tags and/or custom fields work on your provider’s platform, so you can perform the necessary actions such as automations, flows, segments, reports, and so on. We are unable to provide full support on how to use your provider's platform, and it is better to contact them directly with questions related to their platform.

It just works, you don't have to remember to use it, and you can say goodbye to those annoying spreadsheets. The instructions to cancel can be found [here](https://docs.mailfloss.com/how-do-i-cancel-my-subscription). [title] Understanding Your Credits: Subscription and Prepaid [path] Plans and Pricing/ At mailfloss, we believe in offering flexibility and control when it comes to using our email verification service. To help you make the most of your experience, it's essential to understand the types of credits we offer, how they are acquired, and how they work. Each credit corresponds to one email verification, making it easy to track your usage and manage your credits effectively. ### 1. Subscription Credits **What Are They?** Subscription credits are credits included with your monthly subscription. The number of credits you receive depends on your subscription plan level. **How They Work** Subscription credits reset on your billing day. This means that on your billing day, you receive a fresh set of subscription credits to use for the upcoming month. They **do not accumulate or "rollover" from one month to the next.** ### 2. Prepaid Credits **What Are They?** Prepaid credits are credits that you can purchase from within your app. Unlike subscription credits, prepaid credits can be purchased and used even if you have a free account. The advantage of prepaid credits is that they never expire. **How They Work** Prepaid credits allow you to verify email addresses at your own pace. Whether you have a paid or free account, you can purchase prepaid credits to supplement your verification needs. Since they** don't have an expiration date**, you can use them whenever it suits you. ### 3. How credits are used **Verification processes will always prioritize the use of subscription credits first.** Since subscription credits reset on your billing day, by using them first we can help you ensure that you make the most of your monthly allocation while preserving your prepaid credits for those times when you need them most. Use subscription credits with confidence, knowing they refresh on your billing day, and rely on prepaid credits when you need extra control and flexibility. ### 4. When Credits Are Charged Credits—whether subscription or prepaid—are charged **once all contacts from your verification process have been successfully imported**, not when they are verified. This means that **you are only charged when your list is fully loaded into the system**, ensuring clarity and transparency in how credits are used. There should be **no additional charges** unless you initiate a **new verification process**. In other words, once a list is imported, the credit deduction happens, and that’s it—no hidden or ongoing charges from that import. **Please ensure you have enough credits before initiating a verification process. Otherwise, the process may remain incomplete, and not all contacts will be verified.** If you have any questions or need further clarification on how credits work, please don't hesitate to reach out to our support team. We're here to assist you every step of the way!

[title] Do prepaid credits come with the same features as subscription plans? [path] Plans and Pricing/ Prepaid credits come with all verification tests and allow you to use Manual Mode options, but are missing some features mostly related to our email service provider (ESP) integrations that are only available on paid subscription plans. The features only available on our subscription plans include Autofloss, Instafloss, the Typo Fixer, Update/Tagging contacts, additional user seats, automated action options, etc. If you are using our upload tools or our API, you have access to the same verification tests as using an integration. [title] Handle custom fields and fixed typos: automated rules and exceptions [path] Feature: Typo Fixer/ ### Understanding the "mf\_fixed" Field When our automated system corrects a typo in an email address, the corrected email address is labeled with a custom field called "mf\_fixed" if auto-update custom fields is set as the action option, and this will be set to "true." This field is your key to identifying which email addresses have been successfully corrected. ### Handling Unsubscriptions with Automated Rules To maintain control over your email list and ensure that email addresses are handled appropriately, you may have automated rules set up to unsubscribe addresses that have failed our verification processes. To address cases marked as "mf\_fixed = true," you can create an exception in your automated rules. ### Creating an Exception Rule: 1. **Log in to your ESP: **Access your email service provider's dashboard. 2. **Navigate to Automation or Rules: **Find the section in your ESP where you manage automated rules. 3. **Edit or Create a Rule: **Depending on your ESP, you may need to edit an existing rule or create a new one. 4. **Set Conditions: **Define the conditions that trigger the rule. In this case, you're looking for email addresses where "mf\_fixed = true." 5. **Specify Action: **Determine the action you want to take for these addresses. Since they have been successfully corrected, you can add an exception by excluding them from the unsubscription process. 6. **Save the Rule: **Be sure to save the rule to apply it to your email list. We are using Drip for this screenshot, but the process is similar for all ESPs: ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/D25LW2uLo2GwKSk9qybsq_mfunsubifnotfixeddrip.jpg) ### Why Create This Exception Rule? By creating an exception rule for "mf\_fixed = true," you ensure that email addresses successfully corrected by our system are not mistakenly unsubscribed. This helps you maintain a clean and accurate email list while preventing the loss of valuable subscribers due to typos.

[path] Troubleshooting/ At mailfloss, we understand the importance of efficient email verification, especially when it comes to managing contacts within your ESP account. Our Decay Protection feature is designed to streamline this process by automatically verifying email addresses monthly (or with a customized period) across your entire ESP account, preventing your lists from going stale. However, some ESPs lack the functionality to filter out email addresses that have been previously suppressed from email marketing efforts. This can result in unnecessary consumption of verification credits and potential overuse. To address this issue, we recommend the following steps: 1. **Disable Global Decay Protection**: Turn off the main Decay Protection switch to halt the global import of contacts for your account. 2. **Create Segregated Lists**: Generate a separate list containing only the contacts currently being targeted for email campaigns. If you already have such lists, proceed to the next step. 3. **Activate Targeted Decay Protection**: Enable Decay Protection specifically for the segregated lists. This ensures that only the contacts within these lists undergo the verification process, thereby preventing credit overuse on suppressed contacts. You can find a guide for this process [here](https://docs.mailfloss.com/how-to-set-decay-protection-custom-mode). By implementing these steps, you can effectively optimize Decay Protection for your ESP account, ensuring that your verification credits are utilized efficiently and minimizing unnecessary resource consumption.

Why the process isn't completely stopped? [path] Troubleshooting/ What happens is after you cancel a batch verification is that any email addresses not queued are immediately stopped. Email addresses that are early in the queuing process will also be canceled, but any email addresses that are nearly finished verification will be completed. So there are usually some email addresses that get processed after a cancelation request. Please note that cancelations are not recommended unless necessary. Credits are not reimbursed for any email addresses that were processed. [title] Untitled [path] / [title] Spotless: clean other contact fields, not just email [path] Feature: Spotless/ # Spotless: clean every contact field, not just email Spotless finds and fixes messy contact data in your email service provider — names typed in ALL CAPS or all lowercase, phone numbers in inconsistent formats, and junk entries like "asdf asdf". mailfloss already removes bad email addresses. Spotless cleans what's left. Spotless is in beta and off by default. You turn it on per connection. *** ## How it works 1. **Scan.** When mailfloss imports or verifies your contacts, Spotless reads each contact's profile fields and builds a report. Nothing is changed. 2. **Review.** You see the proposed changes and approve the ones you want. 3. **Apply.** mailfloss writes the approved changes back to your ESP, then reads each contact back to confirm the change landed. Nothing is ever written without your approval, and nothing is written automatically as contacts arrive. You choose when to apply. *** ## Turning Spotless on Go to **Integrations**, select your connection, and find the **Spotless** section. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/3cRql6zZ9dXAYROSdk7FE_screenshot-1-the-collapsed-spotless-panel-showing-21-fixable-0-junk.png) The header shows how many issues Spotless found. Click the arrow to expand it. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/KVwC3pfKg4fVIbNA-mLTv_screenshot-2-the-expanded-panel-showing-all-three-toggles.png) ### Enable Spotless Turns scanning on. To build your report, Spotless stores a copy of your contacts' profile details — names, phone numbers, addresses — on mailfloss servers, encrypted. Turning this off stops new contact data from being stored. You need this on before anything else works. Run a scan and floss to build your first report; contacts are scanned during import. ### Fix what we can Allows Spotless to correct values. It title-cases names (`jane doe` → `Jane Doe`) and standardizes phone numbers into international format when you click **Apply fixes now**. This toggle alone does not write anything. It marks the connection as willing to receive fixes. ### Clear out junk Blanks names that are clearly not names — `asdf asdf`, `Test Test` — and phone numbers confirmed invalid. **This is irreversible.** Once a junk value is cleared, mailfloss cannot restore it. The toggle is off by default and labelled accordingly. Some ESPs ignore requests to blank a field. On those connections this toggle is hidden and the panel says so, because turning it on would do nothing. ### Review each change first Recommended, and on by default. - **On** — every proposed change waits in a queue for you to approve or reject, one at a time or all at once. - **Off** — clicking **Apply fixes now** writes every change that clears the confidence bar, with no itemised confirmation. Review also widens what Spotless will offer. Some phone numbers can only be standardized by assuming the country from the contact's address. mailfloss will not make that assumption on its own, so those numbers appear only in the review queue. Approving one tells mailfloss the country is right. *** ## Reading the report Click **View report** to see the breakdown. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/oN_Z7xa6gSx5HMNSiWB78_screenshot-3-the-report-names-phone-numbers-postal-codes-rows-plus-the-other-issues-line.png) - **Names — fixable** — casing or spacing Spotless can correct. - **Names — junk** — entries that look like filler rather than a real name. - **Phone numbers — fixable** — numbers that can be standardized with confidence. - **Phone numbers — need country info** — valid numbers with no country code, where the country cannot be confirmed. These are not invalid. mailfloss will not guess a country code. - **Postal codes — invalid** — postal codes that do not match the contact's country. Reported only; Spotless does not correct addresses. - **Other issues** — problems your ESP will not let mailfloss change. Nothing to approve; edit them in your ESP if you want them fixed. The footer tells you how many contacts were scanned. *** ## Approving and applying Click **Review N changes**. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/2ejdF-wUaQHTynD54EtPK_screenshot-4-the-review-dialog-with-contact-names-blurred.png) Each row shows the current value, the proposed value, and why Spotless flagged it. `plausible-name` means the value looks like a real name that needs tidying, not junk. - **Approve** — queue this change to be written. - **Leave it** — reject it. Spotless will not offer that change again. - **Approve all** — queue every change in the list. Approving does not write anything yet. When you're done, click **Apply N approved changes**. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/IPNxYW1et4gBIu1EEXj0S_screenshot-5-apply-n-approved-changes.png) After the write, mailfloss reads each contact back from your ESP and checks the new value actually landed. If a write does not verify, mailfloss stops applying to that connection and flags it rather than retrying. *** ## Supported ESPs Spotless **scans and reports** on 28 ESPs. Spotless **writes changes back** to the 16 below. Every one has been tested against a live account to confirm that writing one field leaves every other field untouched. | ESP | Fixes names | Fixes phone numbers | Clears junk | | ---------------- | --------------- | ------------------- | ----------- | | HubSpot | Yes | Yes | Yes | | Mailchimp | Yes | Yes | Yes | | Klaviyo | Yes | Yes | Yes | | MailerLite | Yes | Yes | Yes | | Brevo | Yes | Yes | Yes | | Campaign Monitor | Yes | Yes | Yes | | Intercom | Yes | Yes | Yes | | Customer.io | Yes | Yes | Yes | | ClickFunnels | Yes | Yes | Yes | | Drip | Yes | Yes | No | | Mautic | Yes | Yes | No | | Gist | Yes | Yes | No | | Braze | Yes | Yes | No | | Iterable | Yes | Yes | No | | Keap | Yes | No | Yes | | Kit | First name only | No | Yes | **Why some cells say No** - **Clears junk — No.** These ESPs ignore requests to blank a field. mailfloss cannot clear a value there, so the toggle is hidden. - **Keap — phone.** Keap replaces a contact's entire phone list on every update, so writing one number would delete the others. mailfloss does not write phone numbers to Keap rather than risk that. - **Kit — first name only.** Kit's contact record has a first name field and no last name field. On the other 12 scanned ESPs, Spotless builds the report but cannot write changes back. You'll see the report with no fix toggles. *** ## Common questions **Does Spotless change anything on its own?** No. Every change needs you to click Apply, whether or not the review queue is on. **Can I undo a fix?** Name and phone corrections can be changed back manually in your ESP. Cleared junk values cannot be recovered, which is why that toggle is off by default and marked irreversible. **Does Spotless send email or change subscription status?** No. It only edits profile fields. Subscription status, tags, and consent are left alone, and mailfloss verifies that after every write. **What happens to my contact data?** Profile details are stored encrypted, only for connections where you've enabled Spotless. Turning off **Enable Spotless** stops new data being stored. Data is deleted when you disconnect the integration or close your account. **Why does my report show issues that aren't in the review queue?** Those are issues your ESP won't accept changes for. They're counted separately in the report and marked as nothing to approve. [title] How can I tell if an email address typo was fixed? [path] Feature: Typo Fixer/ There should be 3 ways to see which email addresses were fixed. They are: 1. You see a green "fixed" label beside the email address in the mailfloss dashboard. 2. The daily floss CSV report will have a Fixed column, and the cell will have "true" if it was fixed.  3. If you have auto-update custom fields set, there will be a mf\_fixed or "mailfloss fixed" property on the contact with a value of true. If #3, you can then use the property or tag to run the fixed typo through automations and campaigns and use the data in your reporting. [title] How do I get the Typo Fixer feature? [path] Feature: Typo Fixer/ This feature is available to our subscribers only. It is included in the Pro and Business plans and available as an add-on to our Lite plan. The Typo Fixer feature will automatically fix typos of popular email services such as Gmail, Hotmail, Yahoo, and AOL. If manual mode is set, the feature works with the click of a button. If an auto action is set, the process is automatic and hands-free. [title] How does the Typo Fixer feature work? [path] Feature: Typo Fixer/ The way our Typo Fixer works is if an email address fails a verification test, we check to see if a suggestion exists. If it does, we reverify the email address to make sure the suggestion is valid. If it is, we attempt to fix it automatically if you have an auto action set (auto-unsubscribe, auto-delete, or auto-update).  The Typo Fixer works for commonly misspelled email services such as Gmail, Hotmail, AOL, and Yahoo. If you have Manual mode set, you will see a button that says "Fix typos" under the integration where the invalid emails are listed. Clicking that will fix the typos inside your email service provider.  ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/rASYOgvg8Sf-vBLkTEQ-z_1.png) **Note:**  This button only appears if there's a typo suggestion to fix.  **Important:** The Typo Fixer feature only corrects the domain part of the email address. The **local part **(everything before the "@" symbol) cannot be changed to ensure data integrity. [title] Typo Fixer limitations [path] Feature: Typo Fixer/ For most of our integrations that support the Typo Fixer feature, we are able to fix the contact directly by simply updating the email address to the fixed version. There are some integrations, however, that do not let us do this. Rather, we have to create a new contact with the updated address and delete or unsubscribe the old one. The integrations that require us to do it this way are: - VerticalResponse - Sendpulse - Sendlane - Mailup - MailerLite - GetResponse - Beehiiv - Encharge The contact data on the old contact will be lost, so if this is a problem we recommend disabling the Typo Fixer. [title] Fixing typos in company email domains [path] Feature: Typo Fixer/ mailfloss has always corrected typos in common email domains — `gmial.com` → `gmail.com`. It can now also catch typos in **company domains**, like `john@acmee.co` when the real address is `john@acme.com`. Company domains work differently, and the difference matters: **mailfloss never corrects a company domain on its own.** Every suggestion waits in a review queue until you approve it. This feature is in beta and off by default. You turn it on per connection. *** ## Why company domains need your approval With a common provider, mailfloss can be confident. There is one `gmail.com`, and `gmial.com` is not a real domain. Company domains are different. `acme.co` and `acme.com` can both be real, and belong to two different companies. Correcting one to the other would send your email to the wrong business and lose you a real subscriber. mailfloss can often tell that a domain *looks* like a typo. It frequently cannot prove the corrected address actually exists. Rather than guess, it asks. This is why the setting is a *suggestion* feature, not a fixing feature. *** ## What mailfloss filters out before you see anything Suggestions are not raw guesses. Before a correction reaches your queue: - **Dead domains are dropped.** If the corrected domain has no mail server at all, the suggestion is discarded rather than shown. - **Each suggestion is checked against the connection it came from**, so one integration's queue never mixes with another's. - **Decisions are final.** Once you fix or dismiss an address, mailfloss will not raise it again for that address, even on later scans. What remains is the class mailfloss can resolve but cannot confirm — which is exactly the class worth a human glance. *** ## Turning it on 1. Go to **Integrations** and select your connection. 2. Make sure **Fix Typos** is on. Company domain suggestions are part of typo fixing, so the parent setting must be enabled first. 3. Turn on **Also suggest company domain fixes**. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/n3fyz1yCdm9G-l00LjcDT_fix-typos-company-domains-toggle.png) Turning it off at any time stops new suggestions. ### Choosing which suggestions you see Under the toggle, two checkboxes control which kinds of suggestions reach your queue. Both are on by default. | Checkbox | What it means | Uncheck if | | -------------- | -------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------- | | **accept-all** | The corrected domain accepts mail for any address, so mailfloss cannot confirm that this exact mailbox exists. | You only want suggestions mailfloss could individually confirm. | | **unverified** | The mail server did not give a clear answer during verification. | You want a shorter, higher-certainty queue. | Suggestions that mailfloss *did* confirm always appear, regardless of these two settings. Unchecking a box also removes matching suggestions already waiting in your queue. Anything you have already decided on stays decided. *** ## Reviewing suggestions Suggestions collect in your review queue. Each row shows the current address, the proposed correction, and a badge when the corrected domain is accept-all. For each one: - **Fix it** — applies the correction to that contact in your ESP. - **Leave it** — dismisses the suggestion. mailfloss will not suggest it again for that address. Nothing is written until you click **Fix it**. ### Examples | Current address | Suggested correction | | --------------------- | --------------------- | | `john@acmee.co` | `john@acme.com` | | `sarah@microsfot.com` | `sarah@microsoft.com` | *** ## Common questions **Will mailfloss ever change a company domain automatically?** No. Company domain corrections are approval-only by design. This is different from common-provider typos, which mailfloss fixes automatically when Fix Typos is on. **What happens if I ignore the queue?** Nothing. Suggestions wait indefinitely and are re-checked on later scans. Your contacts are unchanged. **Can a suggestion be wrong?** Yes, and that is the reason for the queue. `acme.co` and `acme.com` may be two real companies. Approve a correction only when you recognise the company or the contact. **Why did a suggestion disappear on its own?** Two reasons. You may have unchecked accept-all or unverified, which clears matching pending suggestions. Or mailfloss re-checked the corrected domain and found it no longer accepts mail. **Does this affect email verification credits?** No. Suggestions come out of verification you're already running. Approving one does not cost extra. **Is this per connection or account-wide?** Per connection. Turn it on for one integration and the rest are unaffected. [title] Instafloss delay recommendations [path] Feature: Instafloss/ If you are sending an email such as a welcome email to a new subscriber right away in your campaigns and automations, we recommend inserting a 20-minute delay before doing so while using our Instafloss feature. If it's not ideal to do 20 minutes, then try 10 minutes, and if that's too much, try 5 minutes, etc. The longer the delay the better to ensure the email address gets verified and dealt with if it is invalid, preventing the bounce. It is not recommended to not insert any delay, as it will be impossible to know if the welcome email automation runs first or Instafloss does. The recommended 20-minute delay will cover most of the Instafloss email verifications but some might take longer.  This depends on many factors like how long of a delay before the email address is sent to us from our partner integration, how busy our load is, the type of email address we are verifying, etc. We are continually improving our Instafloss speeds and expect only to improve over time. [title] Feature: Instafloss [path] / [title] Instafloss for GetResponse tradeoff/warning [path] Feature: Instafloss/ Instafloss gives GetResponse real-time capabilities! Follow the instructions to start preventing bounces before they happen. When you attempt to enable Instafloss for GetResponse we require that you read the disclaimer that any existing callback will be overwritten and acknowledge that you understand the trade-off. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/4dqoQynOGvuh6yt8SJq2U_getresponse.png) If you do not know or understand what the callback does, if it exists, we recommend contacting your IT administrator before turning on Instafloss. If you don't have an IT administrator and do not know or understand what the callback does, if it exists, we recommend you do not turn on Instafloss. You can check if an existing callback exists by clicking [here](https://app.getresponse.com/callback). If the URL there doesn't start with "https\://webhooks.mailfloss.com" then this is an existing callback unrelated to mailfloss and will be overridden if Instafloss is turned on. Proceed with caution. [title] Understanding Discrepancies Between Kit and Instafloss [path] Feature: Instafloss/ If you've noticed a difference in subscriber numbers between Kit and Instafloss, it's due to the way each process handles contacts. Understanding these differences can help you manage your email lists more effectively. ### Instafloss We receive new contacts, including both active and complained contacts. After removing duplicates, only active subscribers are flossed. Complained contacts are not flossed because ConvertKit/Kit automatically prevents sending to those addresses. ### Autofloss We retrieve all contacts from the previous day, regardless of their status. This includes active, complained, canceled, and other non-active subscribers. ### Why This Matters The distinction between Instafloss and Autofloss ensures that only active subscribers receive emails while keeping historical data intact. If you want an extra layer of email hygiene, enabling Autofloss can provide broader protection by accounting for all contacts, regardless of their status. By understanding these processes, you can make better decisions about list management and improve email deliverability. [title] What does Autofloss do? [path] Feature: Autofloss/ If **"Autofloss"** is enabled, mailfloss will automatically scan your connected email service provider every day to verify new emails added from the day before. This feature is highly recommended to keep your email list continuously clean and verified. For a completely hands-off approach, combine Autofloss with an auto action, such as automatic unsubscribe or automatic delete. This setup ensures a fully automated email verification process—something many of our customers use, and the reason mailfloss was built. Talk about convenience! 😊 Please note that Autofloss requires an active subscription. You can enable it from the **Frequency** options under the **Integrations** section in the mailfloss app. ![](https://archbee-image-uploads.s3.amazonaws.com/q0k5I8m97LQRRapz7DXqQ-FR0XWGyEUwqr_icDtL2nG-20250225-222157.png) [title] DailyStory Custom Fields Instructions [path] Feature: Update Tags/Custom Fields/ To take advantage of our custom fields feature with DailyStory requires additional steps.

Installing the extension 1. Go to the **Google Marketplace** and search for **"mailfloss email verifier."** 2. Click **"Install"** to add the extension directly to your Google Sheets. ### Step 2. Getting the API key In order to use the extension, you need your API key. Follow the instructions in [this article](https://support.mailfloss.com/article/show/158760-generate-an-api-key) to get it. ### Step 3. Setting up the extension Once you install the extension and get your API key, you will be able to use the extension. For this, you’ll need to enter and connect the API key. 1. Login to the Google Sheets file where you want to use the extension. 2. Click on the "Extensions" tab and, at the bottom, you should find the option "mailfloss email verifier". 3. Click on it, and you will see two options: "Verify emails" and "About". The About option contains information that may be helpful about the extension, and Verify emails is where you should enter to get started. Select that option. 4. A sidebar will open, where you will find an introduction and instructions for the extension, plus a box where you should enter your API key. 5. Enter your API key and click on the submit button. 6. Wait a few seconds for it to connect and, if the API key is correct, you should be in. ### Step 4. How to use the extension 1. Once inside the extension, you will see your credits at the bottom of the sidebar. You will also see a button that says "Verify email addresses".  2. Select the email addresses you want to verify from your spreadsheet and click "Verify email addresses".  3. A new sheet will be created with the name mailfloss results, where you will find all the verification data of your selected email addresses.  4. To verify more email addresses, the steps are the same. Just select the emails you want and click Verify. A new sheet will be created with the verification results. ### Step 5. Review your settings You will notice that there is a tab called "Settings". The extension gives you the option of whether you want to get your results color coded. In case you activate this setting, you will see that in the newly created sheet with the verification data, the column called emails will be colored green or red depending on their validation status.  Below this option, you will see the button "Change API key". In case you need to, the extension will go back to its initial page where you will have to enter the API key again in order to use the extension. When you close the extension it will remember your API key, so you don't need to enter it every time you open it. The extension will ask for your API key only the first time you're logging in, and in case you want to change it in the future.

[path] Development/ Yes, you can access our webhooks documentation [here](https://developers.mailfloss.com/webhooks). [title] Data Retention Policy [path] Policies/ Email addresses are flossed per session. To be accessible within the mailfloss app, mailfloss requires retaining email addresses to provide reporting, exporting, and manual review. mailfloss uses the following data retention policies for email addresses: - The last 5 floss sessions are considered locked so that they are accessible within the dashboard. Locked sessions may retain the email addresses for up to 3 months. If you regularly use mailfloss, using a feature such as Instafloss or Autofloss for example, data will never retain that long. After 3 months data is automatically purged and will no longer be available in the application. - Any email addresses not part of a locked floss session and it was manually canceled will retain up to 6 months. - Most other email addresses are retained for up to 35 days and then are deleted if they are not part of a locked floss session. This is the most common scenario of data retention, especially if Autofloss or Instafloss is enabled. This is the current data retention policy. We prefer not to keep your data for too long, and thus recommend downloading the result reports to keep for your records. We reserve the right to modify the data retention policies at any time.  [title] I'm using the Typo Fixer. What if the suggested email address is already a subscriber, what happens when the Typo Fixer tries to fix the typo? [path] Feature: Typo Fixer/ Many email service providers only allow one unique email address in the database. If the email address already exists in the database, the attempt to fix the typo will fail. If this is the case, the misspelled email address should be deleted instead. The described behavior is true for the following email service providers: - ActiveCampaign - Campaign Monitor - ConvertKit - Constant Contact - Drip - Gist - HubSpot - Klaviyo - MailChimp - MailerLite (will unsubscribe misspelled email address but fail to create new contact) - Moosend - Brevo (formerly Sendinblue) - Sendlane (will unsubscribe misspelled email address but fail to create new contact) - Iterable Other email service providers allow duplicate email addresses and treat them as different contacts. If this is the case the Typo Fixer will successfully fix the email address, and there will now be duplicate entries of the email address.

[path] Feature: Instafloss/ When turned on, Instafloss will scan and floss every new subscriber in real-time with a supported integration. The verification process happens across all lists and the entire account, with some exceptions, which can be sent based on individual segments or lists. All the addresses verified through Instafloss will appear as an integration session on your dashboard the next day. Instafloss is not available on the Lite plan by default but is available as a Lite plan add-on. Instafloss provides real-time capabilities for all supported integrations, except for Constant Contact. For some ESPs, including Gist, Moosend, Sendlane, Braze, Iterable, Customer.io, Klaviyo, and GetResponse, additional steps are required to set up Instafloss. With some ESPs, Instafloss is retrieved on a best-effort basis and is not guaranteed to run for every single new subscriber. Based on our tests, Instafloss successfully receives about 99%+ of new contacts. For reporting, all flosses are aggregated from the previous day and will show up as one session in the dashboard. It can be enabled from the Frequency options under the Integrations section in the mailfloss app. ![](https://archbee-image-uploads.s3.amazonaws.com/q0k5I8m97LQRRapz7DXqQ-sSniJGq8wNgAqoE-tmBP6-20240923-214810.png) [title] What does Decay Protection do? [path] Feature: Decay Protection/ If **Decay Protection** is checked, that means mailfloss will automatically verify your entire connected email service provider email database every month as a default (or depending on your selected schedule), preventing existing emails from going stale (on average, emails go stale at a rate of 2.1% per month because of job turnover, abandoned addresses and domains, etc).  This is recommended in order to keep your list protected from email decay. If you combine that with Autofloss and an auto action, such as automatic unsubscribe or automatic delete, you have a completely hands-off and automated approach to email verification. This is what many of our customers do, what we do ourselves, and why mailfloss was built. Talk about convenient! :) It can be enabled from the Frequency options under the Integrations section in the mailfloss app. ![](https://archbee-image-uploads.s3.amazonaws.com/yGUejq6E8IJ_sYX6JSjSr/KZcQWRAdpdd9CjwsjohVz_4ad92e6b-cdca-412e-bf05-966d6434d94d.png) [title] Benchmark custom field limitations [path] Feature: Update Tags/Custom Fields/ Benchmark has a limitation with their API that only allows a set number of custom fields that are fixed and hard-coded. With mailfloss, we occupy Fields 17 to 24 with our data. That means any data in these fields will get overwritten by mailfloss data.  If you currently have data in these fields and do not want this to happen, we advise not using the mailfloss update custom fields feature and choose another action such as unsubscribe or delete.
