Sending HTML mail through ACT! 2000

Hi. I am trying to send mail to multiple contacts in my ACT database. I have figured out how to create a group – set up an internet mail account in ACT and successfully send the mail out to the group. The thing I cannot figure out is how to send it with HTML in the body. I have an HTML e-mail that I need to “Paste” into the e-mail, and it will not work.

Not sure if I am giving enough info – but please, any help would be appreciated.
