email auto send

Hi i have been looking for a plugin to do the following, currently im using contact form.

When a user completes a form on my wordpress site i need to receive an email with the data entered into the form (this bit is fine) but once they hit submit i need a plugin that can send a pre-defined email to there email addresss entered in the form.

I have searched but cannot find anything i think i must be using the wrong search methids and terms.

Any help appreciated.
