This is a must! When you email be sure your website address is somewhere in your signature at the bottom of the email. Whenever I'm dealing with an interesting person through email I almost always check out his or her website -- almost always. Of course if you are spamming you can rest assured that I'll also be checking out your website so that I can contact your ISP in an attempt to stop the spam.

However, given that you are engaged in proper email communication please believe that more times then not a recipient will check out your website given in the signature file -- especially if they have any reason to believe it is your personal website. People are curious.

Here's a sample of one such signature:

Claude Needham (the place for fun programming)
