Temporary email is useful when its boundaries are clear.

Who can read my messages?

Public inboxes are shared. Anyone who knows the address can read or delete its messages. Private inboxes belong to your account and are available on Pro and Developer. Signing in alone does not make a public inbox private.

How long are messages kept?

Retention depends on the inbox creator’s plan: 10 hours for anonymous use, 24 hours for registered free, 7 days on Pro, and 30 days on Developer. Each message expires from its original receipt time. Reading it does not extend that deadline.

Do I need to open an inbox first?

Yes. Create the inbox before sharing its address. Free users receive a random username and domain. Choosing or reopening an address requires Pro or Developer. Mail sent while an address is inactive is discarded and cannot be recovered later.

Can I send email or use my own domain?

The service is receive-only; it does not send, reply, or forward email. Pro and Developer support private receiving on verified custom domains.

Can I automate verification-code retrieval?

Developer includes an API for your private inboxes. Its OTP event stream watches new arrivals for up to 60 seconds and returns extracted code candidates with metadata and heuristic confidence. See the OTP documentation for details.
