What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
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.
If you want to send a confirmation email in your end, you can setup an email notification, here's a guide on that: http://www.jotform.com/help/25-Setting-Up-Email-Notifications.
If you would like to send a confirmation email to the user who filled out the form or based from the email field in it, then you might want to check out how to setup an Autoresponder, here's a guide: http://www.jotform.com/help/26-Creating-a-Form-Autoresponder.
Do let us know if that helps.
