How to hide your email address (and why you should)
Your email address isn't just where mail arrives — it's your username almost everywhere, the recovery key to your accounts, and the thread that links your identity across every database it sits in. The less it circulates, the safer you are.
What happens when your address gets around
Every signup copies your address into another database. Databases get breached, merged, scraped, and sold. That's how one address ends up in breach dumps, on data broker lists, and in the hands of phishers who now know exactly which services you use. Spam is the visible symptom; the linkability is the deeper problem.
The fix: stop giving it out
You can't un-leak an address, but you can stop feeding the machine. Give every service a forwarding alias instead of your real address. Mail still reaches you — here's how the forwarding works — but each company only ever holds an address you can switch off.
A simple playbook
Use one alias for shopping, one for newsletters, one for social platforms, and fresh ones for anything you don't fully trust. Reply from the alias when you need a conversation. Reserve your real address for people, not companies.
When spam appears, the alias that received it tells you who leaked — block the sender or retire that one address and move on. Your other aliases, and your real inbox, are untouched.
Extra habits that compound
Alongside aliases: use a password manager so leaked addresses can't unlock anything, enable two-factor authentication on your primary inbox, and be stingy with your address in forums, résumés, and public profiles — scrapers read those too.
