Which Strategy Should You Use?
- Gmail +tag — works everywhere, but some sites strip "+". Mail still arrives in your main inbox.
- Gmail dot — Gmail ignores dots in addresses, so
j.smith@gmail.com=jsmith@gmail.com. Lower spam-detection by site filters. - iCloud Hide My Email — Apple-managed forwarder. Random alias, optional disable. Requires iCloud+ for unlimited.
- Custom catch-all — own a domain? Every
anything@yourdomain.comhits your inbox. The strongest option.
How to Catch Leaks
If you sign up for newsletter.com using you+newsletter@gmail.com and later get marketing spam to that exact alias from a different sender, you know newsletter.com leaked or sold your address. Cancel them, block the alias, move on.
