    Survey: one-time submission verification

    marathon girl 2012

      I plan to place a link in an email, to send feedback participants to my feedback form.  Is there a way to track/restrict/validate their participation as a "one-time visit" ? 

      I don't want any given email recipient to reply multiple times to a survey (feedback form), nor is it desirable for said email recipient to copy and paste the link for the world to use.


      Wish to have the link work ONCE for each email recipient.


      [thanks in advance.]
