The situation:


I correctly installed several goals in the account of my website. For people to complete this goal they need to awnser several personal questions. When pressing send the page stays on the same page and a message appears they received an email. When clicking the link in the email they go to a thank you page on the same website. This URL is also used as a goal in analytics.

Problem:

The goal itself works fine. Every day the correct amount of goals are measured (I counted the amount of emailadresses which are added to the measurement in analytics). However, the goals are assigned to the email refferal links. What I want to know is which referrer they initially come from (e.g. Adwords, Google organic, Somedomain.com, etc.). How do I achieve this?
