As is the norm for email deliveries, we always include an unsubscription link in the footer of each delivery. This unsubscription links takes the recipient to a Campaign web application where they can manage their preferences, opt-in/out etc.
What I want to be able to do is whenever a recipient opts-out, identify the source from which they came. Specifically I want to identify the delivery that contained the unsubscription link they clicked on.
I've read the documentation related to tracking in web applications here:
We have marked the opt-out links in our deliveries however a click on these links doesn't necessarily mean the user has followed through with an unsubscribe.
The link in our case takes the user to a landing page (Preference centre) where the user can then opt in/out of one or more subscriptions.
What we'd like to track (probably from the Preference centre) is:
1) The traffic source (name of the delivery) that the user came from in order to land on the preference centre.
2) The opt-ins/outs from each subscription type that followed once the user landed on the preference centre.
I was considering appending an identifier to the unsubscription link (delivery name maybe) that I could then pass back to Campaign whenever the user opts in/out of a given subscription but thought there might be some OOB tracking functionality that could achieve what is needed with less effort.
