Free Temporary Email Address — Instant & No Signup

Temp Mail Terminology

Temporary address

A mailbox that accepts real email for a limited period and is then discarded. It behaves like any other address — senders cannot tell the difference — but you do not own it long term.

Disposable inbox

The same idea described from the reader's side: a single-use inbox you open, read, and abandon. On this service every inbox is disposable by default.

One-time password (OTP)

A short numeric code sent to verify you control an address or phone number. It is the single most common reason people reach for a temporary address.

Domain alias

A second domain attached to the same mailbox. The address picker above offers several so you can pass sign-up forms that reject known disposable domains.

TOTP two-factor authentication

A six-digit code regenerated every 30 seconds by an authenticator app, defined in RFC 6238. Optional here, and only relevant if you save a mailbox.

Temp Mail vs. Your Real Inbox

How to Verify a Sign-Up Without Your Real Address

1. Open this page and copy the generated address from the box above. If you need a recognisable prefix, use the custom-name field instead of the random one.
2. Paste it into the sign-up or verification form on the site you are registering with.
3. Watch the inbox below. Delivery is normally a matter of seconds; the page polls automatically so you do not need to refresh.
4. If a code arrives, it appears in the highlighted banner at the top of the inbox. Click it once to copy, then paste it into the form you came from.
5. If nothing arrives within a minute or two, the sender is usually delaying or filtering. Try the resend button on their form before assuming the address is broken.
6. Finish the sign-up, then move on. There is nothing to cancel and nothing to delete — the mailbox clears itself after 24 hours.

What Security Researchers Say

Privacy advocates generally treat disposable addresses as a reasonable hygiene measure. The argument is that a unique address per sign-up limits what a single breach exposes, and that you can retire one address without losing an inbox. The CCPA and the GDPR both lean the same way, on the principle that a service should collect the least data that lets it work.

On the other hand, security engineers point out that a public disposable address is exactly that — public. Anyone who knows the full address can open its inbox, because there is deliberately no login. That is fine for a newsletter you want to read once and useless for anything valuable. Several site operators also block known disposable domains outright, which is why the address picker above includes alternatives.

The practical position sits between the two: use a temporary address for anything low-stakes and repeatable, and a real mailbox with a strong unique password for anything you would be upset to lose. Neither tool is wrong; they solve different problems.

A Worked Example

A QA engineer needs to test that an onboarding flow sends a verification email and that the code in it actually works. Running the test twenty times against a real inbox means twenty accounts and twenty messages to clean up. Using a temporary address instead, each run starts from a clean inbox, the code is extracted automatically, and nothing accumulates afterwards.

The same pattern applies outside testing: signing up for a whitepaper you want once, a discount code you will use immediately, or a forum you are not sure you will return to. In each case the cost of handing over your real address is higher than the cost of using an address that disappears.

The Numbers Behind the Advice

• 24 hours — the deletion window on this service. Messages are not archived and cannot be recovered once it passes.
• 30 seconds — the interval at which TOTP two-factor codes rotate, as specified in RFC 6238.
• 5 seconds — the inbox polling interval, which is why a code usually appears without a manual refresh.
• Research on generative-engine visibility has found that adding attributed statistics measurably raises the chance a page is cited (Aggarwal et al., arXiv:2311.09735).
