Sending embedded thumbnail

[DAVEinDK]

Embedded Thumbnails.
I need to create an email with text(of course), and an image with a You Tube video embedded.
I have created the mail, sent it to an email account, and it works.
My problem is, that I will be sending this mail to many different recipients over the next few weeks. My question is, how and where do I save the mail, so I can easily send the mail to a new recipient when I need to?
Forwarding no good, tried that
Just want to send the same mail, with same content and of course, the working embedded thumbnail.

Apple's Mail app used to have a Template feature, but they killed it off some time ago (not sure why). The only way to do what you want to do easily is to create that email and save it as a Draft in a user-created folder on your Mac. Here is a detailed description (a bit wordy, but easy to follow) of how to do this.

If you know how to create HTML, you can really customize it and save it as an HTML Signature, then send the email with nothing but that special signature (which is actually your full email). How to do that is a little more complex, and you can probably google the instructions.
