A large part of my job managing email systems is dealing with unsubscribe issues. If the unsubscribe button doesn't work, it's probably one of these issues:

- "Unsubscribed" is not persistent. If they have a logic that subscribes you to their emails (filling out a form), you will get resubscribed.

- You are unsubscribing a different email than you subscribed with (This is like, 75% of cases we deal with. It could be a forwarder, or a POP download, or a DL, etc). - You are unsubscribing via the Google link and not the one in the email (not all systems are smart enough to recognize that).

- Something is broken or someone screwed up the logic. If you reach out and inform them, they may have someone seriously look into it (for our company, this would be me).

Or they are truly are scummy company and ignore unsubscribes or pull your address off of the same purchased list again. If they don't respond to you, pull the email headers and figure out who their host is and report them for abuse.

Honestly I just press the unsubscribe button in apple mail or the link in the message and if those don’t work, mark it as spam.

I also consider having to make any extra action on the website as the link not working.

There's another: a business creates new lists and adds old customers to it. Some popular websites have multiple categories of marketing lists that can be unsubscribed from one by one.
