Not sure if this is the right form to post this...

We are being asked to add an unsubscribe link to all out going email messages. Now I know I can and a URL to the unsubscribe page, but they are asking if it can autofill the receipents email address to autofill the webapge when the receipient of the email clicks on the unsbuscribe link.

We are running GW2014 SP1 on linux

I hope this makes sense
