So, we could have one list for each of our campuses, and then people could create groups for their life group or serve team? Then, people would only be on one list and counted once for MailChimp pricing? Or are you saying that multiple CCB groups could be added to the same MailChimp list?

Yes to both but our app can do this for you, automatically. You can choose to sync specific CCB groups to specific MC groups that exist or you can allow our application to create that for you from our interface.

V2: Do you know if MailChimp counts the same people multiple times if they are on multiple lists? For example, if we have someone who is in a life group list and on our greeters team, would they be counted once in pricing or twice?
