We've used Revive to serve ads in email for several years with success - my question relates to the statistics. Anyone care to guess what percentage of impressions / clicks that Revive reports are from non-humans like Spam filters, virus scanners, firewalls, etc.?
Proof: One of the ad units has had no banners assigned in well over a year, but consistently reports ad impressions at a higher quantity than the number of email opens. I'm assuming that fake impressions are recorded by Revive from spam filters before the email is even delivered to the user. Can anyone confirm this?
Past 7 days stats from Mailchimp and Revive:
340,012 Successful email deliveries
166,893 Total email opens
366,865 ad impressions (ad unit that was filled 100%)
742 clicks (100% filled ad unit)
216,074 ad impressions (no banners assigned)
0 clicks (empty ad unit)
Our standard email tag looks like this:
