LIVE INBOX / NO SIGN-UP
Disposable inbox
Short-term sign-ups, confirmation links, and email verification codes need a clean, isolated entry point. This address is used only during your current browser session—no account or password required.

01 / USE IT RIGHT
Copy, wait, complete
A temporary email reduces your exposure to data collection; it is not a replacement for a permanent email address.
Allow time for delivery
Most emails arrive within seconds to a few minutes. If nothing appears after five minutes, check the spelling and spam rules first, then consider requesting another email.
Leave when you're done
Don’t keep secrets in the inbox long-term. Once the address expires, it can’t be restored, and changing addresses immediately removes the old entry point.
Expiration and privacy boundaries
New inboxes are active for 3 hours by default. Each extension adds 3 hours, but the total lifetime never exceeds 24 hours from creation. This is a receiving window, not a promise of permanent storage. Temporary credentials remain in your current browser session; clearing browser data, switching devices, or changing the address yourself may permanently remove your access.
The sending site may identify and reject temporary domains at its discretion; TmpOne does not bypass those policies. If sign-up involves payment, identity documents, critical recovery codes, or long-term attachments, use a real email address you can keep under your control, or create a forwarding alias you can disable at any time.
Didn't receive the verification code? Don’t keep generating new addresses. First confirm that the submitted address matches what’s displayed, wait 2–5 minutes, then use the diagnostics console to troubleshoot by branch.
02 / WHERE IT FITS
When a disposable inbox is the right call
One test decides it: would losing this account hurt? If not, hand it to a throwaway address.
Grab a whitepaper or trial code
Leaving your real email for a single download usually buys you months of marketing follow-ups. A temporary address collects the confirmation and walks away.
Claim a first-order discount
Promo lists are among the most resold datasets on the web. Claim the code with a disposable address and your primary inbox never enters a list.
Ask one question, once
A community you join to ask a single question doesn't deserve a long-term identity. Receive the activation email and the job is done.
Test your own signup flow
When you need clean recipients to verify deliverability and rendering of onboarding email, a disposable inbox gives you one instantly.
03 / COMPARE
Disposable inbox vs. forwarding alias vs. primary email
Each address type has a clear job. Risk comes from mixing them up.
| Dimension | Disposable inbox | Forwarding alias | Primary email |
|---|---|---|---|
| Lifespan | 3–24 hours | Long-lived, disable anytime | Permanent |
| Account recovery | No — gone at expiry | Yes — mail keeps reaching your real inbox | Yes |
| Best for | Verification codes, downloads, trials | Subscriptions, shopping, lasting signups | Banking, government, work |
| Exposure risk | Zero — the address is discarded | Low — disable the leaked alias | High — a leak touches every account |
04 / COMMON QUESTIONS
The three things people ask before using it
Is a temporary email safe?
The inbox has no password; access rides on your current browser session. That makes it right for low-sensitivity mail and wrong for contracts, receipts, or anything you must keep. Route sensitive correspondence through a forwarding alias or your primary address.
Will websites reject a temporary domain?
Some will. Senders are entitled to block known disposable domains and we do not work around their policy. A rejection means the site wants a lasting contact — switch to a forwarding alias.
How long is mail kept?
Exactly as long as the inbox lives: 3 hours by default, extendable to a 24-hour maximum. At expiry the address and its mail are destroyed together and cannot be recovered, so export anything you need first.
