Have Boards on main admin but still getting emails on other emails?

The PeerBoard Community Have Boards on main admin but still getting emails on other emails?

So I have a few Peerboards (yay!) that I started with different emails. I reallocated them to the same email under the one admin (yay!). However, I still get the PeerBoard marketing/community updates to all the old emails. What would be the best way to limit those to just the one Super Admin email? Should I just unsubscribe with the other addresses? Or is there a setting I am missing? Just want to get the messages once vs. 6x :)

Many thanks!
