Gmail’s Image Caching and Salsa Labs

by Brett Schenker, Senior Deliverability Manager, Salsa

Last week Gmail decided to shake things up some more in the email world by beginning to cache images sent to their email system. You can see this most clearly in your own email when you try to save an image to your computer, it will now say “unnamed” and the urls themselves will change.

An old url will say something like: salsa.wiredforchange.com/o/6157/images/imagename.jpg

These new rewritten urls will be something like: ci4.googleusercontent.com/proxy/wholelotofrandom#/https:// salsa.wiredforchange.com/o/6157/images/imagename.jpg

While many are panicking that this changes how opens are reported, so far this shows no impact for users of Salsa. Since Salsa will only record one open per person, no matter how many times they do, there is no impact by this change right now.

In testing Google's new image caching we found:

  • Emails are still recorded as opened when images are enabled
  • Multiple opens of the same email will not report multiple times in Salsa
  • When you click a link it is recorded as a click
  • When you click multiple links, this is recorded correctly in the "links in the message" reporting in the email summary report.

So for those who use Salsa’s email platform, for now, there is no foreseeable impact.
