Is it possible to embed a video in an e-blast mass email?

Trail Blazer does not allow you to embed videos within your email. For security reasons many ISPs block certain types of attachments that are known to contain viruses, particularly videos along with javascript and flash.

To get around these security constraints, upload your video content to  video streaming service such as youtube, then within Trail Blazer you can create a standard text link or clickable image to redirect readers to your video.
