Well, go to Youtube. Pick up the embed code they offer. Go to Thunderbird, create an html-formatted message. Go to Insert|HTML, paste your embed code in to the box offered.

It may or may not work; it depends a lot on whether your recipient's mail client supports this. Thunderbird itself will not run scripts, so I wouldn't expect anyone viewing your message using Thunderbird to see the viewer.

Are you sure you want to do this? I could find it dreadfully embarrassing at work If I opened an email and it instantly started playing a video.

I did that before posting this and it didn't seem to do anything, Probably because Thunderbird does not support it. I don't want it to auto play just be in the window to be viewed if wanted without someone having to be in my youtube channel. Thanks for the reply. I will just create a simple web page and drop it on my server. More reliable.
