The Cookie That Never Expires
You probably remember when the tracking cookie died. Browsers blocked them, regulators demanded banners for them, and the advertising industry spent years announcing its move to a “post-cookie world.” It felt like a win for privacy.
It wasn’t a win. It was a substitution. The identifier that replaced the cookie is your email address.
Why your email address is a better cookie than the cookie ever was
A cookie lived in one browser on one device, and you could clear it whenever you wanted. Your email address follows you everywhere. You type it into every store, newsletter, app, loyalty program, and login screen. It is the same on your phone, your laptop, and your work computer. It survives for decades.
