Email Suppression List

An email suppression list records addresses or recipients that should not receive particular outgoing messages. It may include people who unsubscribed, addresses that repeatedly bounced, or contacts excluded for other documented reasons. A service business should check this list before sending a promotional email campaign. The suppression list is different from an unsubscribe link: the link lets a recipient request removal, while the list helps enforce the resulting restriction. Suppression categories can differ by message type, so operational notifications require thoughtful handling. Do not silently re-add opted-out recipients when importing contacts into a new marketing platform.
