Temporary email vs. email alias vs. masked email
Three tools that all hide your real address — but they are not the same
If you want to stop handing out your real address, three tools come up again and again: disposable email, email aliases, and masked email. They overlap, but choosing the right one depends on how long you need the address to live.
Temporary (disposable) email
An address that exists for minutes to hours and then disappears. You never register, and there is nothing to clean up afterwards. Perfect for one-off verifications and throwaway signups, but you cannot recover anything once it expires.
Email alias
An alias forwards mail from a second address into your real inbox. It usually lives as long as you keep it, so you can tell which service leaked your address — and simply switch the alias off. Great for newsletters and stores you actually use, because mail still reaches you.
Masked email
A masked address is an alias created automatically by an app or browser, often with a single click. It blocks trackers and lets you revoke a masked address instantly. Convenient, but usually tied to a specific provider or ecosystem.
Which should you use?
- One-time signup or test → temporary email.
- A service you will keep using → an alias you can disable later.
- Everyday privacy inside one app → masked email.
Many people combine all three: a disposable address for a quick verification, an alias for a long-term account, and masked email for day-to-day browsing.
