Hi, I'm using umbraco newsletter, and when a receiver wants to unsubscribe from the subscription through the received email, I want to redirect them to a SurfaceController Action with parameters => the receiver email and subscription id. i.e. Every email has a unsubscribe button, and i want to pass the subscriber email and subscriber id, and unsubscribe the receiver from the mailing list. How can I do that? I want to unsubscribe them in the most easy and out of the box way, please share other opinions. I've searched the net and the forum but I can't find how to manage unsubscription.
