Do you psychos not unsubscribe from things? Or mark them as spam?
Part of the reason you’re getting so many is because they’re making it to your inbox. That’s enough. A LOT of marketers care way more about deliverability than click rate. If their email is getting through, they’re likely to increase volume because it helps deliverability. Going to dead emails that never read them doesn’t matter, it means they can get into boxes with the people who may actually read them. Everyone that doesn’t unsub or mark as spam is helping their deliverability reputation, and keeps them off spam filters.
If you’re getting emails you don’t want MARK. THEM. AS. SPAM.
