    Hi,

    Would it be possible to prevent multiple submission by preventing the same email address from being used twice?

    Hello jeremylwf,

    Yes that is possible to achieve.

    You can take advantage of our "Unique Question" feature and you can limit your form. One you set your form's email field as a unique question, multiple submission using the same email address will not be allowed.

    Here is a guide which should help you:  http://www.jotform.com/help/223-How-to-set-Form-Limits-Based-on-a-Unique-Question

    Hope this helps.

    Do get back to us if you have any questions.

    Thank you!
