To turn on Confirmation Emails:
The confirmation email is automatically sent to the recipient's email address after they complete the survey. It isn't possible to manually send confirmation emails.
The confirmation email is sent a few minutes after the survey taker clicks Done to complete the survey. The email includes the survey title and a link to view answers.
Survey takers can view all the questions they saw when they took the survey along with their answers, including open-ended text and piped text.They can view their answers for 90 days after taking the survey. But if the survey owner closes the collector, the link to view answers will say something went wrong.
