Email works very well for this. I do wish my neighborhood association would move to a Google group, because right now it’s a massive CC list. Mail hosts tend not to like that very much, and it’s not the most privacy-minded solution.

Several other active communities I’m a member of are on mailing lists. The one that switched to a forum platform with email notifications of new threads died fast.

Yeah, cc lists are a nightmare for so many reasons, not least because you can't easily get off/unsubscribe.

Thankfully one of the neighbors “owns” the list and sends out an email with updates any time it changes. You’re supposed to reach everyone by reply-all-ing to the latest one. To unsubscribe, you email the organizer; to subscribe, you ask a neighbor to email them. So, could be better, but could also be worse.
