A nice fix for the companies that, either by malice or incompetence, use one regex for their original email field and then another for the email field used to unsubscribe. IOW, if you ordered something, used "[e-mail]" (which Musician's Friend takes just fine), then went to unsubscribe, the email field regex for that screen will complain about the "+". Off to the spam bucket you go, Musician's Friend, and my purchase dollars now go to Sweetwater.

That was definitely a problem with Ticketmaster. It might still be, but I've long since marked it as spam.
