Both disposable email and email aliases help you protect your real inbox—but they solve different problems. If you want maximum spam isolation, a disposable inbox usually wins. If you need long‑term recovery, aliases are often better.
Disposable email gives you a temporary inbox that exists for short‑term use. You receive emails online without exposing your real address. You can discard the inbox when you’re done.
Try it here: Disposable Email Address.
An alias is another address that forwards mail to your real inbox (or to a mailbox you control). It’s convenient for long-term use, but forwarded spam still ends up in your main account unless you filter carefully.
