Different email clients support different video formats. Playable takes out all the hard work by optimizing video emails to individuals in real-time as the email is opened.
To achieve this Playable creates multiple versions of the final email video. Here is our latest compatibility list of supported video formats by an email client:
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 (video no animated GIF)
Outlook for Mac: MP4, H.264
Outlook.com: GIF (video no animated GIF)
Outlook.com: WEBP
Outlook 2007-2016 for Windows: Static Image (<2% of consumer campaigns)
Samsung Mail: WEBP
Yahoo! Mail: GIF (video no animated GIF)
Yahoo! Mail (Chrome): WEBP
It is worth noting that GIF is limited to 356 colors, while all other formats deliver millions of colors. GIFs will appear of lower quality as the reduced palette is not able to effectively do shading, fluid movement, and other finer points in a video.
To ensure the best quality video emails, start with the best quality source video. We recommend, at a minimum, that the source video be twice the size of how it will appear in the email and in a high-quality video format.
For example, for a 600w video, the source should be 1200w and at least an MP4.
