Mail Format?

Hi Guys 

Just some quick questions.

1) If a mail alert contains some html is there a way to make sure it
comes through as proper markup i.e. HEADER1 instead of <h1>HEADER1</h1>
2) If I don't want to include the alert/test results i.e. &red cpu 100%
in the mail is there a way to do that?

Regards
Neil
