Switched from Litmus after some poor… 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.

Great but lets shoot for the stars! When using marketo tracking links, Marketo encodes the url and it becomes a 200 workable link but when reality, it is a broken or internal link masked as an 301 redirect. It would be a great improvement if we can solve this in EOA. Check at least the redirect or 2 hops after a 301 for the link checker. Overall, everything is great other than some minor issues with rendering clients from time to time.

EoM doesn't handle multiple emails If you send more than one email to EoM "simultaneously", which seems to mean within the same second, it intermixes them, showing different emails for different rendered platforms, or no render (perpetual spinning circle) for some platforms. EoM said that I have to send the emails separately (by which, I think they mean take longer between emails.) That doesn't help me at all.

The price just keeps going up and up The price just keeps going up and up. They say it’s because of new features that they keep adding, but as a dev I just want to test the email rendering and don’t need any of the other features. They are forcing unneeded features onto the users and are charging them. EOA, you need to offer different packages. As a freelancer, £100 a month is just not affordable just to test a few emails per month. I don’t want your other features, stop forcing and charging me for them, please!

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!
