A little search for the html code for creating a form along with a small php script (called from the form placeholder html code) will also do this. A little more effort, but the most flexibility in the end, as you can use this same php code to add stuff to mysql databases and other such things - and it doesn't cost anything.
Maybe this will get you started: http://regretless.com/scripts/scripts.php#dodosmail
This one seems to have a lot of options covered.
