A Suppression List is a list of people who have opted out of the mailing list. With email marketing, it is required to let users opt-out of any email marketing campaigns.

As an affiliate you must use a Suppression List to remove the emails that are on the suppression list from your email campaign you send out.

Sending emails to people on the suppression list is considered spam and will result in your WOW Trk account being closed and no commission being paid to you.
