Emailing a group who use sign-up sheet

Hello,

This is my first time creating a sign-up sheet. I worked through the speed bumps and appear to have everything up. I now have a list that has a bunch of volunteers. I am not seeing a clear way to easily email the group of volunteers. It seems like I might have to go into communicate and individually add the entire list of people one at a time.

Is there a more effective way to do this or am I missing a button somewhere?

I have searched the forums and I am not seeing a circle back or a close out to this. Emailing Sign Up Sheet Participants - #12 by Keneu

Thank you
