Create a draft that resends a sent campaign to everyone in the same audience who didn’t open it. The draft copies the campaign email and reuses the original audience with a “didn’t open this campaign” rule added, so only people who haven’t opened it yet are targeted. This is only available 6 hours after the campaign finishes sending, which gives opens time to register. The response includes an estimate of how many subscribers haven’t opened the original. The new draft is not sent automatically - review it, then schedule or send it.
