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.
Unfortunately, we do not have phone support, but we'll try our best to provide solutions as detailed as possible here in the forum.
If you will setup your Email notifications, you'll see in the "Provide Sender and Recipient Details" the "Reply-To Email" field, you should have an email field that will be filled out by the user of your form. If you setup this, it will allow you to directly reply to the users email address via the notification you received.
If you are looking on to have an auto-reply email when the user submits the form, then you can setup an autoresponder. Here's a guide on that: http://www.jotform.com/help/26-Creating-a-Form-Autoresponder.
I hope that helps.
