I would love to be able to add .GIF or .mp4/YouTube videos into EMP emails to allow for more interactive and interesting emails. Adding movement or interest into the emails may increase click-through rates and overall interest in the content we are sending.

Currently users can insert .GIF images into emails to provide animation, but embedding video files directly is not supported, nor encouraged, due to email best practices for deliverability and mobile network responsiveness. We recommend inserting an image of the video play screen into the email which is linked to the hosted video (YouTube, Vimeo, etc.). This will allow you to track clicks to the video (views) while adhering to email best practices.
