I'm using a Gmail filter that searches and labels mails that contain the word "unsubscribe". It skips the inbox then I check it later to see if I received something worthy.
Oh wow, that's not a bad idea! I wonder if I can do this in Postbox.
That was a good tip. I just labeled it "UNSUBSCRIBABLE" and get a nice big badge that's useful until they redesign Gmail this year and ruin it for everyone.
