    We are running a raffle and would like to limit the entry to one per person. We are requiring e-mail, phone number and name. Is there any way to do this?

    Yes, that would be possible. You can set up "Unique Question" question on your form to do that.

    Here's a guide — How-to-set-Form-Limits-Based-on-a-Unique-Question

    You can also limit form submissions based on multiple fields in your form.

    How-to-Have-Unique-Question-Using-Multiple-Fields

    Here's a sample form — https://form.jotform.com/72826241617962

    You will not be able the form twice using the same email address in your first submission.

    When you attempt to submit the form for the second time using the same email address, you will get the following warning message:

    There is also a way for you to update the warning message. Please see this guide — How-to-Change-Form-Warnings
