Save-the-Date email ecards?

I want to do evite save the dates instead of mailing paper ones. The only problem is, every service I encounter that offers this either requires that you sign up to do your wedding website with them, or inserts some big fat link you can't change saying "VISIT THE WEBSITE" and it directs you to their page. I already have a wedding page with my own url that I made myself. Anyone know of a way to email save the dates but still use my own website and disallow links to anything else?
