I need to find an alternative email solution for my wife, as she is constantly sending out lots of work-related emails with many folks CC'd and BCC'd. She is NOT spamming, she's just... prolific. Because of this she often runs afoul of the mail servers and she gets a "time out" where she cannot send mail for an hour or more.
I know we could do an announcement list, but that would not allow her to add people easily unless they were already subscribed. Is there another option to manage email to larger lists that anyone can recommend? Need an app that is web- or Mac-based.
