We have our events setup to auto register people for the mailing list when they sign up. But no matter if they cancel, paid, pending, or wait-listed everyone gets the email. which can some times be good initially. But we have times where we can only accept a certain amount of people and we only want to send to the paid, and sometimes the pending. It would be nice of we could remove people automatically from the Acymailing list when they cancel. Or be able to select each status so you can pick any combo of paid, pending, canceled or waitlist.
