Hello @Kari-AnnR5,
Most email clients do not support embedded videos, even if you could include the custom html. The coding necessary to play the video directly in the email is often considered to be a security threat, which is why all of our video blocks actually create an image place-holder, which then links back to another source. We don't currently have an integration with Bomb Bomb specifically, however if they can provide you with a link for the video, you could link any image or button to open the video outside of the email client.
