How do I unsubscribe from a mailing list?

1. My Account → Click on the profile to edit → Click on Edit My Mailing List Subscriptions (nav link or scroll down)

2. Unsubscribe → Indicate the reason → Unsubscribe 

You also have the option to remove the club from the list of your memberships. My Account → Click into Profile → Go to Memberships → Edit → Delete this Membership

If you still get emails from them, it is probably because the Event Organizer is cutting and pasting email lists. If you contact the event organizer, they will be able to get you squared away.
