Great tool, but slow and with lots of bugs Email on Acid is a great tool, I'm using it om daily basis, but it's really really slow, sometimes scteenshots will not going to show, sometimes I will get half of the screenshot (the bottom half of the email...), it's just buggy. And when I say sometimes, I mean often. I hope you are working on making ot better and better, as the idea of the tool is great!

AMUST to check emails compatibility The system is a MUST to check emails in multiple browsers. Their pricing is affordable and the offerings are on par with competitors. Do find that troubleshooting one email does require creating new projects so I wish there was a better way to keep track of a template without new tests over and over.

A robust, reliable email testing tool While my company has had an Email on Acid subscription for a while now, this is my first time using it and I love it! The ability to fully QA my emails and ensure that the product going out to our database is optimized, accessible, and completely tested gives me confidence in our deliveries. The step-by-step guide for campaign testing is so user friendly that I learned while testing an upcoming email send. I would recommend this tool to anyone in need of a robust, reliable email testing process, and I'm excited to check out the Analytics options next!

So helpful! Email on Acid had helped us optimize our emails across all devices and email platforms so that they render exactly how we want them too.

Excellent service for email developers and designers I have been using Email on Acid for over 5 years now. It’s become and invaluable tool to deliver emails that work well both on the desktop and mobile. Needless to say, the preview screens have saved me a ton of money in hardware.
