Innovation is Learning What Doesn’t Work


Jan. 21, 2013 Update:
Mozify is now no longer in Beta, and is available to our paid subscribers, at no additional cost!

We’d like to start by saying, thank you to everyone who has shown your support for Mozify! So far, we’ve had an outpouring of interest in our private beta release, several of you have tweeted about it and a few have even blogged about it!

As excited as we are to try something new, being experimental can sometimes have its drawbacks. At Email on Acid, we believe that blogging is as much about sharing fixes as it is about sharing real life experiences. We sincerely hope that our users learn from our mistakes – especially those who are trying out Mozify in private beta.

Our Story

After hours upon hours of testing and reviewing our latest email we were certain that we had all of our bases covered! Not only did we test using our service (results here), we also tested it in a few different devices that we plan to release soon, including the Android 4.0 (Ice Cream Sandwich), the Xoom (running Honeycomb), Outlook 2013 and

Unfortunately, after we sent our final blast, we noticed that our email did not render properly in IE based rendering engines.

The Culprit?

In order for Mozify to work in Outlook 2007 and 2010, it uses the Outlook conditional statement:

<!--[if gte mso 9]> ...  <![endif]-->

Turns out, our sending ESP converted the above to:

<!--[if gte mso 9]> ...  <!-->

Bummer right? So after all that testing, our sending ESP manipulated the original source rendering our email somewhat broken (results here).

What We Learned

Although we make numerous recommendations throughout our blog, we broke one of our own cardinal rules: Always send your email from your sending ESP for testing. In this situation, we were so focused on testing Mozify that we bypassed this crucial step.

Note: You can do this in our system by sending to your Email on Acid inbox located on your dashboard.

If you are not in charge of your final blast, consult with your customers.  Have them send you a test email. You can either grab the source of their test or have them send it to your EOA inbox.


Woody Allen once said “If you are not failing every now and again, it’s a sign that you’re not doing anything very innovative.” Even though we urge best practices, our failure in this case to follow our own recommendation is humbling and we are blogging about it in hopes that you don’t make the same mistake.

We plan to test Mozify using several of the most popular ESPs and we will work closely with each of them to resolve issues that might come up. When we release Mozify to the public, we will provide an ongoing list of email services that it is tested and supported in.

  1. The ability for an email marketer to have images replaced with a mozaic should prove to be a large benefit. We’ll be curiously watching as this product is rolled out to see the larger sets of metrics showing increased click through rates come back.
