About the mail.9inbox.com inbox
Every address on mail.9inbox.com is served by the same mail infrastructure as the rest of 9inbox: messages are accepted at the SMTP level only if the recipient exists, parsed and sanitised before they are stored, and pushed to this page over a live connection rather than waiting for you to refresh. Verification codes are extracted on the server, so an OTP arriving on mail.9inbox.com appears as a badge you can copy with one tap.
Which domain you use matters more than it looks. A growing number of websites compare the domain of a sign-up address against public lists of disposable-email providers and reject anything that matches — so whether a signup succeeds often comes down to which domain you happened to pick, not to anything about you or the address itself. If mail.9inbox.com is refused somewhere, switching to another domain from the list below is usually enough, and premium domains are kept off those public lists specifically so that they keep working.
The lifetime rules for mail.9inbox.com are the same as everywhere on 9inbox and depend on your plan rather than on the domain: ten minutes for a guest address, twenty-four hours with a free account, and no expiry at all on Pro and Business. Messages follow their own retention window, shown as a countdown next to each one. When either timer runs out the data is deleted rather than archived, and mail sent to an expired address is refused at the SMTP level instead of being quietly accepted and dropped.

What a temporary inbox cannot do for you
Every disposable mail service shares these four limits. Most of them bury the details in the terms of service. We would rather you know now than find out at the worst possible moment.
Anyone can send to this address
Only this browser can open your inbox — someone who knows the address still can't read it. But there is no password: clear your browser data and the inbox is gone for good, and once an address expires, the name can eventually be claimed by someone else. Never use a temporary address for banking, payment wallets, government portals, work accounts, or anything you would be upset to lose.
Messages delete themselves
Mail is removed automatically once its retention window closes — one hour on the guest tier, three days on a free account, ninety days on Pro. The countdown is shown next to every address, so nothing disappears without warning. If you need a message later, download it or upgrade before the timer runs out.
You cannot send mail from here
9inbox receives mail only. There is no compose button and there never will be. This is deliberate: a disposable service that can send mail becomes a spam relay within days, its IP addresses get blacklisted, and then it stops receiving mail too. Receive-only is why messages actually reach you.
Some websites block disposable addresses
A growing number of sites check sign-up addresses against public lists of disposable domains and reject them. If a site refuses your address, switch to a different domain from the list below and try again — that usually solves it. Premium domains are blocked far less often because they are not on the public lists.
Other domains you can use
If a site rejects an address on this domain, try one of these instead.
Questions about mail.9inbox.com
Yes. Creating an address on mail.9inbox.com costs nothing and requires no account — the address at the top of this page is already yours. Paid plans exist for people who want addresses that do not expire, longer message retention and access to premium domains, but nothing on this page is behind a payment.
That depends on your plan rather than on the domain. A guest address on mail.9inbox.com lives for ten minutes and can be extended with one click, a free account raises it to twenty-four hours, and on Pro and Business addresses do not expire at all. The remaining time is displayed next to the address.
No. 9inbox receives mail only, on mail.9inbox.com and on every other domain we operate. There is no send capability at all, which is deliberate: a disposable service that could send would be used for spam, its servers would be blacklisted, and then incoming mail would stop arriving too.
Pick a different domain from the list on this page and try again. Sites that reject disposable addresses do so by matching the domain against a public blocklist, so a second domain usually gets through. Premium domains are deliberately kept off those lists and are refused far less often.
No — and this is true of every temporary mail service, not just this domain. There is no password on a guest inbox, so anyone who knows the address can read what arrives in it. Use mail.9inbox.com for signups, newsletters and downloads. Do not use it for banking, payment wallets, or any account you would be upset to lose.
