I think I must have clicked on receive board mail

I think I must have clicked on receive board mail in a room on the hangout.
I am not playing that particular stock any more and tired of my email going off every time someone post in their. I cant find a stop board mail button any were.

Can you help, maybe with simple instructions even a bronson could understand, lol

Thanks in advance, I just gave you 25 more person marks Big T.
