Email verification Action Options
When mailfloss finds an invalid email in your email service provider (ESP), the Cleanup tab of your integration decides what happens. The setting applies to every list in the connection, and you can change it any time. You have four or five options, depending on the integration.

Ask me first is the safest option. mailfloss lists the emails it found invalid in the Waiting for you tab, and nothing changes in your ESP until you decide. From there, you can unsubscribe, delete, or update custom fields for the contacts, report a status as incorrect, or ignore it.
Basically, we’re gonna show you the results on a list and you will decide what you want to do with them

Unsubscribe is the recommended option. mailfloss automatically unsubscribes all failed results, so they stop receiving campaigns. mailfloss asks you to confirm before it turns on, and it can't undo an unsubscribe, but you can resubscribe a contact in your ESP at any time. A switch under Unsubscribe also updates the custom fields.

Delete from your ESP (for example, Delete from AWeber) automatically deletes all the email addresses that
failed the verification process, and is irreversible. Once deleted, the contact is gone for good and you won’t find it inside of your lists anymore. Before this option turns on, mailfloss shows what your last run would have deleted and asks you to type the account name to confirm.

Update a field writes the verification result to custom fields or tags in your ESP, indicating when each invalid email was flossed and why it was marked as bad, so your segments can exclude it. This option is reversible. We consider it an advanced option since you need to know how tags and custom fields work in your ESP.

Report only is the reporting option. All it 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.
