What differs between them
Honestly: the title, the subtitle and the accent colour. All seven present the same five-section form and queue through the same engine. The engine you pick is recorded on the campaign, so Campaigns reads as a list of recognisable announcements rather than seven identical rows.
Choose the one that describes what you are sending. Nothing behaves differently if you choose another.
