Yes, you can customize the Thank You message that is displayed when a respondent completes your survey.
Optionally, you can also specify a web page (URL) to send the respondent to instead once they have completed the survey.
Using Skip Logic?
Even if you are using skip logic in your survey, you can still use the custom Thank You Message or Redirect. This triggers when they have "naturally" completed the final page in the survey or if your logic specifies to * Complete Survey *.
Note: This functionality is only available on paid accounts. Free accounts will display a generic thank you message.
