Disposable Email Address: free, with inbox, no signup

Behind every disposable email service is a set of domains configured as catch-alls: the mail server accepts any address on the domain, whether or not it has ever been issued, and files the message under whatever local part was used. That is what makes instant creation possible: when this page loads, the server picks a random local part on one of our domains, records that it belongs to your session, and from that second any mail sent to it is routed into your inbox here.

The address is then receive-only. The domain accepts mail but is never allowed to send it, which is why a disposable address cannot be used for spam. Messages that arrive are stripped of scripts and tracking elements and shown inside an isolated frame; verification codes are detected and surfaced so you can copy them without opening the message.

The last piece is rotation and deletion. Each address has a fixed receiving window; when it closes, the server stops accepting mail for it and the local part is retired rather than recycled. Stored messages have their own retention clock and are permanently erased when it runs out. A good service also rotates the domains it offers, because the oldest and best-known ones gradually end up on blocklists.

Which brings up the one friction point every user eventually hits: some sites refuse disposable addresses. Signup forms can check the domain against public lists of known disposable email domains and reject matches — a legitimate choice for a forum that wants accountable members or a trial that is being abused, and there is no trick that reliably defeats it. What you can do is try a different domain from the picker when it is shown, since newer domains are less likely to be listed; try a temporary Gmail address, which is a genuine @gmail.com address rather than a disposable domain; or, if the account is one you want to keep, accept that a disposable address was the wrong tool and use one you own.

The three words describe one object from three angles. Temporary email, or temp mail, is the broadest term and simply says the inbox is short-lived. Disposable is the industry’s own term — it names the category of domains built to be thrown away, which is why blocklists are called “disposable email domain” lists. Burner email is the everyday name, borrowed from the burner phone, with its emphasis on anonymity: an address that cannot be traced back to you and that you will drop as soon as it has served its purpose.

The longer treatment of that last term — what a burner is for, how it compares with a throwaway and an alias, and when it is not enough — has its own page: burner email. The practical summary is the same on both: use a disposable address when the exchange is short and one-way; use an alias when you need to keep hearing from a sender without revealing your real address; use a real account when you need to send or to log in again later.

Disposable email services are easy to build badly, and you are handing one your verification codes, so it is worth knowing what separates a sound one from a careless one. These are the checks we hold this service to.

Receive-only, with no way to send. A service that lets anyone send from an anonymous address will be used for spam and phishing, and its domains blocked everywhere soon after. Receive-only is both the ethical design and the one that keeps the addresses useful.

No login and no account. A service that asks you to register, or quietly ties inboxes to a profile, has moved the privacy problem rather than solved it. Here, access to an inbox is held by the browser that created it and by a recovery code you choose to save — nothing more.

A published deletion schedule. You should be able to see how long an address accepts mail and how long messages are stored, and the service should enforce both on the server. This page shows both timers above the inbox and states its retention in its privacy policy.

Sandboxed message rendering. Mail arriving at a disposable address is, by definition, from senders you do not trust. It should be shown with scripts and tracking pixels stripped, inside an isolated frame that cannot touch the rest of the page.

Private inboxes. Some older services show the same public inbox to everyone who guesses the address — dangerous, because whoever reads your signup confirmation can often reset the password. An inbox should be readable only by the browser that created it or by someone holding its recovery code.

A working abuse channel. A trustworthy service publishes an address for reports and acts on them. Ours is in the footer of every page, with a dedicated abuse page explaining what to send.

The common thread is a site that wants an email address and offers little in return. Verification codes for one-off registrations are the biggest single use: the code arrives here and the account is created without your real inbox ever being involved. Close behind are gated downloads — reports, templates and trials that live behind an “enter your email” form — and discount codes that are only sent to new subscribers.

Then there is everything that would otherwise follow you home: forum sign-ups, comment sections, public Wi-Fi portals, contest entries and any form where you are not yet sure the other party deserves a permanent way to reach you. Developers use a fresh disposable address for every run of a signup flow, so welcome emails and password resets can be checked without polluting a real mailbox.

A disposable address is a poor fit for anything you will need to return to. It cannot send. It expires, so a password reset or two-factor fallback sent next month will go nowhere. And once retired it cannot be recovered by you or by us, so any account registered with it is one you may be locked out of permanently.

So never attach one to a bank, a payment service, a government portal, your employer, or any account that holds something you would miss. For those, use an address you control; if you want privacy from a particular sender, use an alias that forwards to it. A disposable address is for the moments you want to forget — and it is very good at exactly that.
