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.

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!
