A suppression list is a list that contains email addresses that you wish to permanently exclude from future emails you send using our service, or addresses that were automatically added.
You may add any email address based on a prefix (name@), a domain (@domain.com), or by using the full email address (firstname.lastname@example.org).
To manage your suppression list, go to your Settings > Manage Suppression Lists
Select a category (address, domain, or prefix) and click on the Add an entry button at the top left.
You can only add individual emails.
For security reasons, these addresses cannot be removed from the suppression list.
