Just two things I've looked at that could enhance the experience on EoA. 1.- Avoid the two clicks I need to do on the main page once logged in to see my projects. 2. Automatically update my test on mobile and desktop devices when I save my changes on the HTML area.

Great product, a must need for email marketing to do it right! Using this tool has yielded over a 15% increase in user engagement.

Support was really patient with me as I got the contract set up!

Switched from Litmus after some poor customer service and aggressive sales calls. We tend to use for only HTML/CSS testing rather than the extended marketing tools but in terms of what we use it for I think it's been excellent so far and actually faster and more reliable than Litmus despite being much better value.
