What is a suppression list?

Uploading A Suppression List

A suppression list is a list of email addresses that you want to exclude from ALL campaigns. Typically they may have unsubscribed from previous campaigns or may be emails that have bounced. Adding subscribers to your suppression list prevents any future emails being sent to them.
