The laws are not unreasonably great. There is no actual blocker to them spamming you again. There’s many ways to maliciously comply like opting you out of a tiny category of their email and making that less obvious so they can keep emailing you unwanted spam. And the law doesn’t let you take them to court for abusing you. That’s why platforms like Bandwidth.com and Sinch have so many spammers as customers - it’s just revenue for them.
