I have set up a double opt-in list in ExactTarget and a corresponding Web Collect form. If a user correctly subscribes, received the double opt-in mail and gets set to active, but then decides to unsubscribe again, that user remains as status "unsubscribed" in the list database even if the Web Collect form is used again to resubscribe.
Is there a way for a user to resubscribe who changes his mind weeks after unsubscribing?
