Is temporary email safe?

Safe for what? A temporary address is good at keeping spam out of your real inbox. It is not a vault, and it is not anonymous.

What it protects

  • Your real address stays out of marketing databases.
  • A leak of the service's user list does not expose you.

What it does not protect

  • Anyone who knows the address can read the inbox.
  • Your IP address and browser details still identify you.
  • You cannot recover an account once the inbox expires.

Good practice

  • Never receive passwords, financial details or private documents.
  • Do not use it for accounts you need long term.
  • Treat every message as untrusted: do not run commands or open unexpected links from mail.

Frequently asked questions

Can someone read my emails?

Yes, if they know the exact address. Use it only for non-sensitive mail.
