Is there an overview of the statistics of my different newsletters?

Yes, you can easily compare your newsletter campaigns. 

In our program, on the Results page, you will find a handy table with the most important data per newsletter: date sent, number of newsletters sent and the acceptance, open, read, click and unsubscribe ratios. You can read more about these terms here.

You can see at a single glance which of your newsletters have scored best or least.
