When a survey reminder is sent, it automatically targets all recipients whose status is Pending, Viewed, or Started. As a result, it"s currently not possible to send reminders to only a specific subset of individuals who haven’t completed the survey.
However, as a workaround, we can download the list of participants who haven"t completed the survey and send the invitation again. To download the email list for pending participants, go to Distribute Tab>>Sent>>Click on Total numbers>>Filter pending>>Download CSV file.
