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.
That is possible by either of the two methods below.
1. You can setup an autoresponder: http://www.jotform.com/help/26-Creating-a-Form-Autoresponder
2. Or you can set the recipient address using the field name.
Here's an example, first get the field name of your email field.
In your email notification (not autoresponder), you can add your field name in the recipient.
