These contacts clicked an opt out link in one of your promotions.
A manually suppressed contact. The contact was either imported directly to the suppression list, or marked as suppressed using the check box in your active audience area.
A signup that hasn’t clicked the confirmation link yet. It’s normal to have some unconfirmed contacts in your suppressed list. Once confirmed, the contact will automatically move to the right list in your active audience.
Marked As Spam
These contacts clicked the spam button in their inbox when receiving one of your promotions.
These are email addresses that are totally unknown, obsolete, incorrect and will never be delivered to the recipient. (If you spot obvious typos like firstname.lastname@example.org (instead of .com), you can unsuppress them and then change the email.)
These are email accounts that often have full mailboxes, their domain is temporarily down, or they’re currently not able to receive email. Mad Mimi retries all Soft bounces until we’re sure they won’t get through.
The most common form of General Bounce happens when a firewall exists on the server of the recipient and prevents them from receiving email from outside their network. This is common in the case of corporations that do not receive email from unknown sources. Mimi retries all General Bounces until we’re sure they won’t get through.
These indicate that a particular message could not yet be delivered, but that the server is still trying. This bounce type is usually resolved when retrying.
