For a hyperlink the easiest way is to make some static text that says, for example, [email protected]
and then, if you select the textbox and look in your property inspector panel
(below the font dropdown) you will see a long input box with a link symbol to the left of it. Inside this put: mailto:[email protected]
This will mean anyone using an email client such as outlook or outlook-express ,etc, can click on the link and send you an email.
For a more dynamic solution you can use "asfunction" inside an html box. There is a tutorial in the tutes section, or if you need further explanation just ask.
You can also assign a subject. Just for variety, I've put this on an "email me" button.
Hope this helps
