How can I receive submissions that posted before we upgraded the pricing package?

We received emails with only partial information and we are trying to see if we can retrieve the submissions that were submitted before we upgraded our monthly package.

If some of the fields are empty, that means users has never filled those before submitting the form. In most cases, this is because the field is set as optional, not required. If you want the fields to be mandatory, set each as required in the field settings.

I would also suggest viewing your submissions page to see the list of submitted data: https://www.jotform.com/help/269-How-to-view-Submissions. There are issues wherein the email is missing some fields, but they are available on the submissions page. In this case, the fields are not being added in the email. We mostly suggest re-creating the template to fix the problem.
