How to write a HTML link in an e-mail

When writing e-mail that involves telling someone about a webpage, it is recommended to write the complete URL, including the http:// prefix, instead of just writing the last part of the URL.

For example, instead of writing www.envprogramming.com in an e-mail message, write http://www.envprogramming.com

Many e-mail programs will 'render' such text as a link, letting people quickly and easily click on the link in the e-mail message to view your suggested site. Chances are, more e-mail programs will recognize addresses starting with the http:// prefix than those which do not.
