Thanks for the feedback! It's impossible for us to tell what percentage of the total number of emails sent the 110,000 impressions represents because our server only gets hit when images are loaded. If images aren't loaded our server is never hit, and it's as if the email was never sent.

The total CTR across all 110,000 impressions was 0.42%, however we log an impression both when an email is being composed and when it is read on the other end. So if we discount the false positives for composing impressions then the CTR jumps to around 0.91% which is incredibly high given that the banners are not at all optimized.

We're working on better analytics to be able to separate legitimate impressions from composing impressions, but don't quite have that functionality yet.

Thanks again for commenting I really appreciate it!
