To protect against accidentally adding invalid, stale, or unuseable addresses to your subscriber list, you can import contacts as unsubscribed to create a suppression list.
Each list in your MailChimp account is separate from the others, so your suppression list won't be global. You'll need to create a separate suppression list for each list in your account.
In this article, you'll learn how to set up a suppression list from a CSV, TXT, or Excel file.
Before You Start
Here are some things to know before you begin this process.
- To complete this process, you need an existing list in your account. Don't have one? Create a new list.
- Suppression lists only require an email address field. Make sure your suppression import file does not contain additional fields or subscriber information.
- This suppression list process can't move existing subscribers to the Unsubscribed category of your list. To mark existing subscribers as unsubscribed, use the bulk unsubscribe tool instead.
