Limit the responses of your questionnaire per device or per contact
Limit per device is included starting from the Essential plan. Limit per contact in included in the Professional and Enterprise plan.
This guide will explain how to use the features Limit your responses per device and per contact.
You've made a great-looking questionnaire (if you haven't yet, log in here to get started) but you may want to stop over-enthusiastic respondents from completing the questionnaire more than once! Read below to see two ways how to prevent multiple responses from the same respondent.
You'll find the options in the Share tab.
Limit your responses per device - This feature will place a cookie on the respondent's browser so that they can only complete the questionnaire once. If they really want to, they will still be able to use a different device to do the questionnaire again.
Limit your responses per contact - You’ll send each contact a personal link to the questionnaire which contains their UID (you can create this after uploading the contacts in My Contacts). If a respondent returns for a second try (even if it’s on a different browser or device), they will only see the Final screen of your survey. The feature checks the UID of the link with the contacts you’ve added and therefore knows who has already taken the questionnaire.
When you turn on Limit your responses per contact, you can determine how many times each contact can enter the questionnaire.
Send out the survey link to your contacts and include the UID of the specific respondent into each link.You can add “?rid=UID_123” to the link. The 123 is the number of the respondent that will be variable. Click here to learn more.
Be aware that since the check is done on our server this feature won't be available in offline mode.
