Unsubs across multiple lists
Hi, first off I want to say we've been testing sendy and it looks pretty awesome.
My question is, we have a db of users, and from time to time we send targeted emails to certain groups of users, so it seems like ideally we'd create a list of users from our db, upload it , and send, which all seem to work fine. The next time we do that though, when a new list is created there could be some overlap of users between the old list and the new list. If people from the old list have unsubscribed, is there a good way to ensure that the new list will respect that unsub field?
