Not All Email Clients Are Created Equal

The quality of video playback inside an email can vary significantly depending on several factors. The most important of these is the email client being used.

Different email clients support different video and image technologies. For example:

  • Gmail supports animated GIFs with a limited color palette of 256 colors.

  • Apple Mail supports HEVC, which allows for millions of colors and higher visual quality than standard MP4 video.

Because of these limitations, the same video can look very different depending on where it is opened.


How Playable Optimizes Video in Email

Playable’s patented platform automatically optimizes video and live streams in real time, at the moment the email is opened.

For each viewer, Playable dynamically adjusts:

  • Video format

  • Frame rate

  • Resolution

These adjustments are based on the viewer’s:

  • Device

  • Email client

  • Network connection

This ensures fast loading times and the best possible viewing experience, regardless of how or where the email is opened.


Please note: To obtain the best quality for your video email campaigns, you should always use a high-quality source video. We recommend at least a 1200-wide MP4 video.
