How to Re-authenticate Inboxes
Mailflow will lose permission to an inbox if there were changes in the security settings of the inbox, the email account is no longer active, app access has been revoked, or there was a security check by the email provider.
When this happens, the inbox will stop sending auto-warmer emails.
To let users know, we send an email notification that the inbox needs to be re-authenticated.
