Embed Videos in Email Template
Lasso recommends that Users do not embed videos in Email Templates because some email applications strip them out and/or won't accept large attachments.
As an alternative, you may upload the video in a video-sharing website (e.g. Vimeo, YouTube, etc.), take a screenshot of the video, and upload the screenshot as an image in Lasso. You may then link the image into the video link. The same would apply to video emails such as BombBomb or Eyejot.
