JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I believe what you are looking for is an autoresponder. This will let you create a email notification that will be sent to the user who is filling out the form. Here's the guide: http://www.jotform.com/help/26-Creating-a-Form-Autoresponder.
If you have other concerns, please do not hesitate to create a new thread here in the forum.
