Wondering if there's any documentation or manual for MassMail.
I've sort of stumbled through it, but when I sent the actual mail, it only went to 17 addresses out of a possible 150+. I don't want to keep testing this out without understanding how it's designed to work and end up sending multiple emails to the users.
Can anyone even just provide super simple steps in an outline format. Don't need exact details either, just the big picture.
Thanks for your assistance,
