You can insert as many videos into an email template as you need.

If you have a video email template then copy the video place holder (insert video here) and paste it into the locations where you want additional video. Adjust size, alignment, etc. then save your work.

You can either go ahead and insert your videos now or make a copy this template in which you insert your videos, saving the original for future multiple video sends.

In the event that the email must open into a landing page, the first video will auto play, the others will not.
