Hey @doinel89 great question!

You can definitely upload an MP4 file to create your videoask! In terms of recommended dimensions, we tend to say record in landscape mode 1920 x 1080 pixels - but you might want to do a bit of testing as the videoask will dynamically adjust how it looks depending on what device it’s being played on.

It’s not possible to fully embed a videoask into an email right now, you can do a partial embed which produces a gif that can be clicked on and the videoask will open in a browser tab. Alternatively you could hyperlink to the videoask which would also open in a new tab.

We have a Help Center article on this here if you’d like a bit more information on what this looks like. 

Hope that helps but let us know if you have more questions! 

Thanks @Grace for the helpful response!
