Unsubscribe Button

My contacts still remain in the campaign after using the unsubscribe button. I followed the directions on the AllProWebTools website and it even shows up in the contacts timeline that they unsubscribed. However I have to manually remove them from the campaign, is this normal?

It is normal. Unsubscribed button allows you to opt-out a list of email addresses so they will not receive your marketing email but that doesn't remove contacts from the email campaign.

Once someone unsubscribes, they can no longer receive marketing emails from you, regardless of any campaign or tag they are a member of (they can still receive emails to assist them in resetting their password or invoices when they make a purchase from you)
