How can I send HTML in an e-mail from an asp page, I use code similar to the one layed out bellow to send text based e-mail, is it very different to send HTML e-mail?

Set sendmail = Server.CreateObject("CDONTS.NewMail")
sendmail.From = "me"
sendmail.To = "you"
sendmail.Subject = "the bain of e-mail"
sendmail.Body = "yeah whatever"
sendmail.Importance = 1
sendmail.Send

Thanks in advance to any help
