Boomtown Email Spam

I don't want to turn off emails from boomtown, there are plenty of emails they send that I want to receive and read.

But even if you already bought a ticket you get your inbox demolished by emails like this.

I wish I could opt out of these and only receive emails such as "band sign up open" and the various storyline/after movie releases.

It seems like whoever runs boomtowns email marketing has set it to "jilted ex stalker" mode!
