Did you know?
You can run custom reports on message statistics via the Report Writer?
This will let you customize a report on any Campaign and message within that campaign. Including multiple messages for comparison. It can be scheduled to run in the future, and will even email the results to any group you like. You can also download it as a .csv file, .pdf, or .html file. I've attached a screenshot of a test to show you some fields you can include in the report for a message.
You can set this report to run when you set up the campaign and message (they have to exist first, of course), but at least you could run it without being in attendance.
