How do I create a format for future Windows Live Mail messages?

I want to create an email message that I can store someplace in one of my folders that I can use over and over again, just filling in the blanks as needed,  so to speak.  When I "save" it the message went to the drafts email folder just fine, but the first time I used it to send to an addressee, the draft was gone. How do I save a message that I create so that I can re-address to others as needed without having to re-type the text over and over again?

Thank you. Sara
