Reply to comment by AccomplishedShoelace in ELI5: Why does every mail subscription seem to have an unsubscribe button? I have seen this even for the scammiest subscriptions. by OldDew

It's law.

A worldwide law?

FYI there are lots of places in the world that do not have this specific law. Or it doesn't get enforced.

They all have national companies that still use the unsubscribe function. There is a Mimecast guide on keeping your e-mail reputation with ISPs up so you don't get spamlisted. Basically conforming to RFC 2822 SMTP, which includes unsubscribing functionality.

It's actually Newton's 4th law so I'd assume universal.

It isn't a worldwide law, but it is a US law. And since a significant percentage of e-mail users are based in the US it would be foolish for a company to risk violating that law.
