What happens if I import a CVS file to a current list and the CVS file contain an email that has already unsubscribed from my list?
HI waimarketing, welcome to the forums! By default, all unsubscribed email addresses are added to a suppression list, which prevents email addresses from being automatically re-subscribed when a list is imported into the app. So the skinny is that unsubscribed email addresses won't be tagged as active again, unless you remove them from the suppression list. Hope this helps!
