Do Your Subscribers Want More (or Less)?

It may be best to run this summary report based on one particular email publication at a time. This way, you can analyze how your subscribers react to mailings with more content compared to mailings with less. If you can manage to send out a lot of content, and still get a lot of click-throughs on your mailing, then you know you are doing things correctly. Otherwise, maybe your mailings need to thin out the content so the good stuff really shines.
