Here’s the thing most people don’t know: spammers aren’t keeping careful lists of who asked to be removed. They’re running bulk operations, blasting millions of addresses, and they have no idea which ones are real. When you click that “unsubscribe” link or fire back a reply, you’ve just answered that question for them.
As the FTC puts it, all that does is confirm it’s a good, active address. You went from being a random entry in a list to a verified, real human who reads their email. That’s valuable to them.
And it doesn’t stop there. According to the University of Colorado’s IT office, “live” email addresses like yours can actually be resold to other spammers. So instead of solving the problem, you’ve potentially handed your address to a whole new wave of people who want to clog your inbox.
The move is simple: don’t reply, don’t click any links, just delete it. If it came from a legitimate company you actually signed up with — think a store you ordered from or an app you downloaded — their unsubscribe link is generally safe to use. But if something feels off — random sender, weird subject line, offer you never asked for — treat the whole email like it doesn’t exist. Delete and move on.
