If you wish to use your own email program, our tool will generate a generic link that you can send to your respondents. This link is not unique for each respondent.
As soon as a respondent starts filling out a survey a cookie will be placed on their computers so the survey can only be filled out from that device once every 168 hours (12 hours in case of surveys based on our COVID-templates). The respondent can still fill out the survey a second time from another computer, a smartphone or a tablet.
In order to change this, go to your survey Settings, click on Options and change the number of hours mentioned next to Can answer again after:
Then click on Save to confirm your changes.
If you want to enable respondents to immediately fill out the survey again, then please follow the steps as described under Allow multiple submissions at the end of this article.

If you reduce the time of life of the respondent cookie, this will not affect cookies already out there. Those cookies already have an expiration date. So those respondents will not be able to answer again until the cookie already on their device expires. The new hour setting only affects future respondents.
Say a survey has a respondent cookie setting of 168 hours (7 days). 100 respondents answer with that setting. Then they change it to 12 hours. The 100 respondents that answered still have a cookie for 7 days and will not be able to answer until the cookie expires. Unless ‘allow multiple submissions’ is turned on. When ‘allow multiple submissions’ is on, not only is the respondent cookie ignored, but also deleted. Also with that setting on, no cookie is placed at all. So if a survey goes from ‘allow multiple submissions’ to ’12 hours’, it will work directly, since there have not been any cookies placed yet.
