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.
Unfortunately when submissions are deleted, they're deleted from our database as well, so they are no recoverable.
If you downloaded a backup or have your submissions in a report, then you can recreate it and import them using our import tool: Import-App-Easily-import-your-Excel-or-CSV-data-into-JotForm
If you had email notifications in your form, you can also check the info submitted there and recreate the submissions and then import them by following the guide given above.
The same if you had email auto-responder in your form, here is also a guide that will help you to find the email history for the email addresses you're using: How-to-View-All-Your-Form-Email-History
If you have any question, let us know.
