Is there a way to build a persons email address into a url so that when they follow it, the page it goes to already has their email address in a form field for unsubscribing from a list. (long story, but have several scripts doing a job and want people to easily unsubscribe)
Want to be able to provide them with a link they can click on to do the deed without having to fill anything in.
I see this done a lot, and one of my clients does this, but I'm not completely clear on the technical detail.
I do know that after the "unsubscribe" URL is inserted in each email, a ? plus a unique code taken from the subsriber database is tacked on to the end of the URL. When a click goes to the site, a script reads the info after the "?".
I don't know all the ins and outs of this method -- that's someone else's department and he's away for the next four weeks.
The visitor never fills in a form, they only see "you have successfully unsubscried from our newletter."
