In know you're running a web site with classic asp already.

So I would

Create an asp page to add that customer id to an unsubscribe list which could be a foxpro table..

In your html email body create a call to that page.

Have a scheduled foxpro job reading that unsubscribe file and looking for new entries and update that customer record to indicate they are now excluded.
