They don't. Period. Full Stop. There are tons of companies that I have told to stop sending me emails that just... continue to do so. And some that won't _allow_ me to tell them to stop (I need to create an account to tell them not to email me... but they shouldn't be emailing me if I don't have an account).

So no, they don't work.
