Not all email clients are created equally!

The quality of the video that plays in the video email when opened varies greatly depending on a number of factors but the email clients used is the most significant.

For example, Gmail supports GIF with 356 colors while Apple Mail supports HEVC with millions of colors with quality better than the popular MP4.

Playable's unique & patented platform optimizes the video or live stream to the individual, in realtime, as the email is opened.

We optimize the video format, frame-rate, and resolution for each viewer depending on the device, email client, and network connection to ensure every viewer enjoys quick loading times and the best viewing experience possible.


Please Note: To ensure the best quality for video email campaigns always use a high-quality source video. We recommend at least a 1200 wide MP4 video.
