Very disappointing company ethics I had a free trial which I forgot to cancel and was charged $179 for. I canceled my subscription on the day I was charged and have since tried to contact the company via email, phone, Twitter and their contact form - with no response whatsoever. I obviously understand that this is my own mistake for not cancelling in time but would have expected the company to be more forthcoming - or to at least reply to any of my requests. Quite sad to see that their business relies on such shady tactics, rather than customers who actually want to use their product.

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!

Always a relief to know what our emails… Always a relief to know what our emails look like on multiple platforms/OS. Would be great if there were suggestions on how to adjust the HTML code when the design looks different on certain OS (e.g. iphone X) though.

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.

The resolution for this issues doesn't… 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.
