In short, there is no email testing platform, like Email on Acid & Litmus, that can properly or thoroughly test video email campaigns, as they will not actually play the video during the tests.

That said, there are a few benefits they do provide:

  • It does show which email version will play video and which will show a static image by the image in the test.

  • They are a quick and easy way to review your email template across a wide range of email clients and devices.

Testing of video email should comply with the Playable compatibility list below:

  • Apple Mail: MP4, H.264, HEVC

  • Apple iPhone Mail (iOS12+): MP4, H.264, HEVC

  • Apple iPhone Mail (iOS11 & earlier): PNG

  • Apple iPad Mail: MP4, H.264, HEVC

  • Google Android: WEBP

  • Gmail: GIF

  • Outlook for Mac: MP4, H.264
