Unsubscribing

I receive multiple e-mails from CoW, and I have decided I do not want to play the game.

I was using it as my Total War games on Steam weren't working at the time. Now they are.

I have tried just to "unsubscribe" through my e-mail, but it just leads me right back to the home page of CoW.

I do not see a Support Option on this page, or the main page of CoW. I do not want my account, and I do not want to receive any notifications through e-mail.
