The Exclude Previous Respondents option allows you to exclude respondents who have already participated in the same survey from the recipient list when creating a new survey collection group. If this option is not enabled, respondents who have previously answered the survey will be able to receive and respond to it again.

This feature is only available when collecting responses via email from respondents already registered in the data space. However, if the anonymous collection option is enabled, the Exclude Previous Respondents option cannot be used.

To exclude previous respondents, select Exclude Previous Respondents in the Advanced Settings area when creating a new collection group.

This option is useful when conducting the same survey periodically but wanting to collect responses from new respondents each time. Common use cases include satisfaction surveys or NPS surveys conducted regularly for brands or services.

For example, if you conduct an NPS survey for a specific service every month, you may want to exclude respondents who participated in January and February when running the March survey. In this case, activate the Exclude Previous Respondents option to ensure the March survey is only sent to new respondents.
