It's possible for your contacts to unsubscribe themselves from specific lists in your account, rather than unsubscribing from all of your communications. To allow this, you can use a preference centre.
Read more about the preference centre.
Sometimes, however, you might want or need to suppress contacts from a specific list yourself. You can do this using a file import.
Before you start
Things you need to know:
Suppressing contacts from a list can only be done using a file import, so you need to have a .csv, .txt. .xlsx or .zip format file of the contacts you want to suppress.
Suppressing contacts from a list works at a contact level. You can’t suppress only a contact’s email address or mobile number from a list.
Learn more in Understand contact and channel suppressions.When you suppress contacts from a list, they are suppressed from that list only. The contacts continue to be a part of your master Contacts list, and any other lists they are subscribed to.
