    I use Jotforms for contest entries. How do I limit entries to one per e-mail?

    Asked by DildayTV on June 11, 2011 at 11:26 AM

    I used Jotforms for a Super Bowl contest, and thought that we had set up then for entries to be limited to one per e-mail address.  Do I need to set this up every time I add a new form?  I have some people entering dozens of times, which is counterproductive, and costs me more with Jotforms.

     

    Thanks,

    Hello Jeff,

    Currently there is no way to limit submission entries to one per email address. What you can do instead is to limit submissions to one per IP address.

    To set your form to accept only unique submissions:

    1.  Go to Setup & Embed tab
    2.  Click the Preferences button
    3.  In the Preferences window, click the Advanced Settings tab
    4.  Set Unique Submission to Strict Check

    You may also set to Loose Check but this can be bypassed by using another browser or clearing the browser's cookie. Strict check, on the other hand, may be disadvantageous if your target users are on the same network, using the same IP address, such as in schools or organizations. It is up to your discretion on which submission check to use.

    Hope this post was of any help to you. Contact us again if you need further help.

    Thank you for your response. I did as you suggested, and it turns out I had already set this for Strict Check.

    Any other advice?

    Thanks,

    Hi Jeff,

    The strict check feature only verifies the IP address of the computer used by the submitter. So if the same email address is submitted using another computer, it may still be submitted. Unfortunately, that's the only solution we can offer you at this time. It's not a complete solution, but it would somehow help curb spam submissions for your contest. We apologize for the inconvenience.

    Please let us know if we can be of further assistance. Thank you for using JotForm!
