    Hello. Is there a way to make it so that your form will only accept a submission from an email address one time - to make it so that one person cannot submit multiple submissions.

    Hello jessinglis,

    You can enable on your form the unique question setting. By assigning it to the email address on your form, it will only allow the person to make a submission based on the email address he is submitting, and he cannot make another submission on the said form more than once.

    Here is a sample guide on how to enable this on your form: https://www.jotform.com/help/223-How-to-set-Form-Limits-Based-on-a-Unique-Question

    If you have questions or if you need clarification or assistance on this matter, please let us know.
