Use the Subject and Body properties to specify the message subject and body text, respectively. A body can be in a text or HTML format. In the latter case, you must also set the IsHTML property to True. For example,
Mail.Subject = "Sales Receipt"
Mail.Body = "Dear John:" & chr(13) & chr(10) & "Thank you for your business. Here is your receipt."
or
Mail.Subject = "Sales Receipt"
Mail.Body = "<HTML><BODY BGCOLOR=#0000FF>Dear John:....</BODY></HTML>"
Mail.IsHTML = True
