Email Marketing Specialist Marketing and Advertising ### "Functional, but a long way behind the competition" 3.0 Overall Rating 3.0 3.0 Ease of Use 3.0 3.0 Features 3.0 3.0 Customer Service 0.0 0.0 Likelihood to Recommend 1/10 March 17, 2022 Pros The main attraction that Email on Acid held for my business was the lower cost, in comparison to the main competitor in the field, Litmus, both as an email editor and for screenshot testing of emails in different email clients. Email on Acid has a wide range of supported clients, including some that Litmus does not include. Cons Email on Acid has a wide range of supported clents for screenshot testing, but this coverage is distinctly lacking in several key areas, notably dark mode in Gmail on Android/iOS. Switched from [Litmus](https://www.capterra.com/p/178360/Litmus/) I was looking to save on costs, but unfortunately Email on Acid's feature set was lacking and I ended up switching back.

Pros With every user having a different journey, email on acid is a great tool to use to check your HTML coding and layout so your emails look crisp and clean in any viewing platform.

Pros One of the things I love most about Email on Acid is you can run unlimited number of tests across desktop, mobile and tablet size devices. I switched away from Litmus to Email on Acid and with unlimited tests along with all of the other great features, I'm never going back!
