I want to add source tracking to my Craft CMS site. Using Google Analytics I can track users through just about the entire process but can't see them as they go through account registration.
I want to simply add a query parameter to the {{ link }} from the activation email.
I can see that if I add {{ link }}&source=test that the additional query param shows up, however what I really want is something like this:
&source={{ craft.request.getCookie('traffic_src') }}
However the above solution returns the activation code and source= which leads me to believe that it is undefined
What is the best way to approach this problem of accessing a cookie for a user in one of Craft's email messages.
