Getting rid of email notifications

I'm getting email notifications about new games, game updates, cancellations and basically everything associated with the game sessions. I have turned off all the email notifications in my account, because I don't want them, but I'm still getting a constant stream of them coming through.

Is there a way to stop these? Is there a bug in my account? If I'm in the wrong forum, please let me know. I'm not sure if there's just something I'm missing, or if there's a bug somewhere.
