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.
I think you are referring to deleted submission. Unfortunately, this is not possibles. Once it gets deleted it also deletes from our servers.
The only option is to check your email account and recover the data from there. You must have received the submission email when the form was submitted. Alternatively, you can check your account "Email History" and check the submission email which was sent. It will give you the complete email content as well. The following guide should help you: http://www.jotform.com/help/293-How-to-view-all-your-form-Email-History
Hope this helps.
Do get back to us if you have any questions.
