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

Report as spam and unsubscribe. If they send you more emails they are in violation of the law for the canned spam act.
