We like to send out announcements about new games and rewards that often include free chip links. 
We do not have a set schedule for when we send emails. We send them at different times and to different segments of our community.  
When you first connected to Facebook, we took the email address that was on file for your Facebook account and subscribed it to our emails. If you no longer use that email address or have accidentally clicked 'unsubscribe' in the body of one of our emails, contact us with your email address so that we can add you back to the list.
