If a subscriber is on multiple lists and a campaign is to go to all subscribers on those lists will the system detect the “same” email address and only send once?
Yes, the system will automatically de-dupe your list. A contact (an email address) will only receive one instance of the campaign regardless of whether they’re on every list you’re sending to.

Excellent - thanks Brian.
I thought that must be the case but couldn’t see it anywhere in the documentation.
Cheers
