A research panel opt-in survey asks customers whether they will give feedback again and on what terms, so later studies go to people who said yes. This template takes about half a minute: a welcome screen that explains the panel, how often they would like to hear from you, the topics they want to give feedback on, and a consent box to join.
It is written for engaged customers, shown once as a popup in your web app to signed-in users or sent by Usertick to a contact list. Either way, the answer must belong to a known person: Usertick email ties each answer to the recipient's contact, and in your web app Usertick.identify() passes the user's email with the answer.
Results shows the share of each frequency and of each topic, and how many of the people who saw the consent box ticked it. In the inbox, filter by an answer, such as Pricing, to find the customers who joined for that topic, then add them to a contact list for the next study.
