Enhance the functionality of Cancel & Update pages
I think it would be great if the Cancel page (that subscribers go to when they click the link in an email) would list all the current autoresponders the person is subscribed to and allow them to selectively unsubscribe from individual lists. Right now it is an "all-or-nothing" unsubscribe.
It would also be great if the "Update" page could list more than just an email address - if it could list the address/phone number, etc fields (admin selected, of course) for them to update as well.
The "Cancel" page does do exactly what you have described. The customer may pick and choose which autoresponders they wish to be removed from, or they may choose to remove themselves entirely.
Your suggestions for the 'Update' page are great, and we will certainly consider this in our future plans.
