We started our first email list a little over a month ago. We pre-populated just a months worth in the auto-responder as a starting point. Sure enough, a few people have rolled off the end and stopped receiving emails, so we created some more content an added it to the system. We have follow-up messages that have intervals beyond the range of everyone on the list, but each person that had rolled to a status of 'inactive' is still showing as such. Can anyone tell me how we get those people receiving the new content that was added? Thanks!
