Once a company wouldn’t stop emailing me despite unsubscribing. I sent them multiple emails with no response.

Then I heard that if enough people mark a sender as spam, Google starts automatically considering them spam for everyone. I emailed them to let them know this, and told them if they didn’t remove me, I would mark them as spam which would affect them majorly.

They replied to my email within minutes and told me I was unsubscribed and would never receive another email from them lmao
