When I changed course I just went to see the admissions tutor for the course I wanted to do and sounded out whether it would be possible. It was just an informal chat and everything followed on easily from there.
I imagine that you'll have to see this tutor at some stage even if you write the email, so my advice would be just to go and see them anyway.
