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.
Just to verify that I've understood your question; You'd like to know if you can reply to a user directly after they've submitted your form?
Yes, that is possible. To do this you would need to select the existing email field where your user fills in their email as the "reply-to" address. You'll be able to reply to the users email id by adding this field.
However, some email clients such as Microsoft Outlook, etc are not supported with this feature and they don't display "reply-to" email addresses.
However, if it is a case where you want to send an auto reply to your users when they submit your JotForm you can achieve this using the Auto-Responder feature.
Here's a link to learning how to setup an Auto-Responder:
I hope this helps.
