Unfortunately not, but we have a work around!
Unfortunately videos don't work in the email newsletters, the various email apps like gmail, hotmail etc. won't display them. The best way around this is to use a still image/frame of the movie and add that as the holding image, and link it to wherever you host the video, such as on your website, or Youtube.
Add PLAY or something similar into the button text box. If you're feeling a little more ambitious, why not add a triangular play button on top of the video so that it looks like a video and when they click to play, the user will be directed to the webpage to watch it.
