I've contacted PayPal asking to be unsubscribed from having a monthly email about my zero account balance with them. They said they couldn't unsubscribe me. I don't have any details other than 1 credit card with them... So I'll never have a "balance", so their email is spam to me. I never signed up for correspondence from PayPal about this. That they refuse to fix it is weird. I get exactly zero bulk email in my inbox... Except for this PayPal nonsense.
