The resolution for this issues doesn't seem applicable for our client, specially when we were not presenting the issue on litmus or the mobile part of Email on Acid.Also with the pixel sizing information provided doesn't seem that the particular mailings were not going over.

I am a freelance Email Developer, and since I purchased a monthly EOA membership, my clientele has increased by 60%.Clients love the fact that I can test their emails on my own and send them a link where they can see how their emails are rendering. I rarely have to go looking for work now. Love EOA!

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.

Switched from Litmus after some poor customer service and aggressive sales calls. We tend to use foronly 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.
