Populating email results.

I'm trying to send an email at the end of a captivate project, that will take the certificate and put it in an email, as well as populate the subject line of the email to something like "Quiz name taken".  I've figured out how to get the certificate to come up in captivate, as well as send the email, but I need to take it that final step.  Any idea how I can do this?  I'm guessing that there is maybe some external scripting involved...but not sure.  Any help would be greatly appreciated.
