Sendlane email verification options
When mailfloss finds an invalid email in Sendlane, the Cleanup tab decides what happens. You have five options. The setting applies to every list in the connection, and you can change it any time.
Before explaining the five options, make sure you have properly connected Sendlane 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 Sendlane account.
To choose an option, go to Integrations, open your Sendlane integration, and click the Cleanup tab:

Ask me first. The safest option. mailfloss lists invalid emails in the Waiting for you tab, and nothing changes in Sendlane until you decide:

The Waiting for you tab appears only when emails are waiting. Select the emails and click Unsubscribe, Delete, or Update custom fields. You can also report a wrong status with Report incorrect, or dismiss an email with Ignore.
Unsubscribe. The recommended option. mailfloss unsubscribes the contact from Sendlane, so it stops receiving campaigns. mailfloss asks you to confirm when you choose it, and a switch under the option can also update the mailfloss fields. You’ll see the contact in Sendlane as “Unsubscribed” to your lists. You can resubscribe the contact in Sendlane at any time.
Delete from Sendlane. Removes the contact for good, so you won’t find it in Sendlane anymore. Before Delete turns on, mailfloss shows what your last run would have deleted and asks you to type the account name to confirm.
Update a field. mailfloss writes the verification result to custom fields in Sendlane, so your segments can exclude invalid emails. This is reversible. You can also use the fields to sync with your other databases and CRMs, or in automations. You can find this information in the contact details, and then scroll down to the "Personalization" section.

Report only. mailfloss emails you the results of the latest floss session. Nothing changes in Sendlane. Like a traditional email verification service, it gives you a report of the verification results for the connected Sendlane account and nothing more.
