Edit the text on the Coursepress Enrollment Confirmation email

This site sells digital downloads, physical products and courseware. When the user purchases a physical product and checks out and creates an account, they receive an email with the subject line "Enrollment Confirmation" and states that they enrolled in "" course.

Ideally if they created an account without enrolling in a course, I would like the email to say basically they created an account and not they enrolled in "" course. Is it possible to have two different emails sent out - 1 for creating an account or 2 for enrolling in a course?

If not, where is the file that I can edit the text so that at least it reads thank you for enrolling or registering...?
