My job is to build and run email marketing systems. Even in modern enterprise mailing platforms it's remarkably easy for unsubscribe systems to break. Here are the most common troubleshooting things that come up: - Your email service may strip out the unique URL that unsubscribes you. In which case you may go to a blank unsubscribe page. If it's not well designed, you may think you are unsubscribing but really you submitted an empty form request. - (We can't always do one-click unsubscribe anymore because some modern SPAM filters work by clicking every link in an email for you.) - Similarly, the unsubscribe page can often be just a web form. Some blocking software like Ghostery may think it's a marketing form and straight up disable it. - Some other team or department in the company set up their own email service for customers or leads without telling the marketing department and doesn't do anything to coordinate the opt-out process (This happens remarkably often.) - The MOST COMMON reason unsubscribes don't work is some set of forwarding rules. Someone signed up on the website with the address for a mailing list, or a junk email that forwards it to their actual email address. We can't magically guess the right address to unsubscribe from (we had a case where 8 different people on a 15 person product team tried to unsubscribe the list, and one person on the team kept resubbing them every time).
