Five ways to know who answered your survey or interview
From a name question to unique links generated from a CSV
A comparison of the five common ways to tie survey or interview answers to the people who gave them: a name question, an ID in the link, invitations sent by the survey tool, unique links generated from a CSV, and panel IDs. Use it to choose a method before you send, especially if you plan to chase people who have not replied. Koji uses the CSV route for AI-moderated interviews.
