By this I am assuming you are talking about using a form to allow users to input data, and that data is sent by email to you when the users hit submit. If so, I would suggest using the CGI.pm module.

Ovid has a great offsite (and free) Web Programming course that will help you to learn how to implement this, provided you know a little bit of HTML and a little bit of Perl. And if you try a Super Search for CGI.pm and forms, you should come up with quite a lot of nodes that deal with your query.

Hope it helps, and good luck!
