The custom survey URL is used when you need a concise, easy to remember URL for the survey. This can make it easier for respondents to access the link.
Example:
company.SurveyAnalytics.com
research.SurveyAnalytics.com
If we try sending out the survey using the email addresses those details won't be tracked under reports as the customized URL acts as anonymous link.
This means that the short name you entered is already being used by another user.
