I am developing a survey which is an election ballot and will share via email campaign. Only those on the email contact list are allowed to participate/vote. I selected the option that they can only participate one time to eliminate duplicate votes. But is there a way to ensure that if someone forwards the email to another, that person will not be able to participate? I can’t find any information on this.
If you are using an email campaign link, by default these links are one tine use. So if one of the link recipients filled out the survey, and then forwarded their link to someone else, that other person would not be able to take a second response with that same link.
I hope this helps clarify!
