    One Submission per Email Address

    Asked by fourtwonine on October 23, 2012 at 03:25 AM

    When setting up a survey, is there any way to prohibit users who have already filled out the form with a particular email address from taking the survey again with the same email address?  Thank you!

    No, sorry, we don't have such a feature yet. What we do have in place is an option to limit a user to one submission only based on their IP address (strict check) or browser cookies (loose check).

    Kindly go to this link for more information:
