Propagating a form field with email from url

[stcrim]

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.

any thoughts???

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."

I'm pretty sure things like automatic unsubscribe links and automatic form field 'filling-out' would have to be a feature either built-in or added to the list management script.

I'm pretty sure you'd have to use a funky "?" URL, and the script would have to have a section explicitly telling it how to interpret the info after the "?"
