What is a suppression file?

So what is a marketing suppression file? A suppression file is simply a file of records that you should be removing from your database. These can be goneaways (people or companies that have moved address), could be deceased people (for obvious reasons) or people who have requested not to receive communications via email or telephone.

How do I use a marketing suppression list with my campaign?

There may be situations where you need to use a suppression file of contact email address to ensure they are not included in a particular campaign. A suppression list is not the same as the unsubscribed contact list-- a suppression list can be independently uploaded and applied to any campaign, where those Contact emails are not in the unsubscribed status.
