Hi, I'm launching an online course and would like to create marketing automation to keep the members engaged with the content? Is this possible? I tried to create it through the normal automation route but it allows me to only create an automation for people who have signed up for a specific mailing list but not for members list. Is there an update coming to this feature or any way to go around it? What I would like to happen is that if person X signs up for the platform and completes part 1 of the course but doesn't continue to part 2, they would get a reminder. Or even less customised so that all members would get regular reminders. Any tips?
