Removing unsubscribes from your lists
When going through your campaign report you may notice that some of your contacts have unsubscribed from your list.
Unsubscribed contacts will not receive any of your future campaigns and do not count towards your subscribers limit. Unsubscribes are maintained in your list so you can't accidentally re-subscribe them later.
All unsubscribes are at a list level, as opposed to a global account level.
If you need to manually unsubscribe a contact, learn how here.
