Years ago, I played "Mob Wars: La Cosa Nostra", "Pirate Clan", "Viking Clan" and "Zombie Slayer" by Kano (as known as Kanoplay) at roughly the same time.
My problem is that I still get email notifications of events taking place in these four games on my Gmail account years after I stopped playing. I have pressed the "Unsubscribe" button to remove myself from the mailing list (notifications@kanomail.com) many times, but the notifications still keep coming.
What do I have to do to stop these notifications for good?
