Is there an easy way to remove all unsubscribers from my contacts? I don’t want them cluttering up my contact list. And I don’t want to go through each unsubscribe one by one.
See this help file on List Hygiene. You can create campaign sequences, tags, and actions that all work together to do many of these things automatically. Before you delete a bunch of contacts, be sure there is little hope that you can get them to re-engage.
If you’re sure you want to delete them: for information on deleting contacts based on email status, see Remove Unengaged Contacts
To get a solid idea on what all the different email statuses mean, see Email status icons explained.
