A real temporary address that catches every message, pulls out the verification code for you, and deletes itself when the timer ends.
Built on our own mail servers, not a shared mailbox someone else can read.
An address is waiting before the page finishes loading. No form, no captcha, no email to confirm.
Mail is pushed to your browser over a live connection the moment our server receives it. No refreshing, no waiting for a poll.
One-time passwords and verification codes are detected in incoming mail and shown at the top of the inbox with a copy button.
No account, no personal data. When the timer ends the address, its messages and attachments are permanently purged.
Messages render as the sender designed them, inside a sandbox that cannot run scripts. Attachments up to 10 MB can be downloaded.
Create inboxes and read mail from code, with codes already extracted. Ideal for end-to-end tests of your own signup flow. Read the docs.
Use a throwaway address for the sites that only want your email so they can send you marketing. People use it every day for:

A disposable inbox is the right tool for half of your online life. Knowing which half matters.
One-off signups and verification codes, free trials and downloads, forum registrations, giveaways, newsletters you want to read once, and automated email testing through the API.
In every one of these you need the inbox for minutes, and its disappearance afterwards is the feature: nothing of yours is left behind to leak in a data breach or to be sold to a marketing list.
Anything you will need to log back into later. Because the inbox expires permanently, password resets for accounts registered with it become unreachable.
Never use a temporary address for banking, healthcare, government services, work accounts, or ongoing two-factor codes. For those, a permanent address or an email alias is the right tool. The safety guide spells out where the line is.
The free inbox is the full product. Pro is for people who use disposable addresses every day.
Small utilities that run entirely in your browser. Nothing you paste is sent to us.
Every address you see here is backed by a mail server we run. It accepts messages over standard SMTP from anyone, parses them, scans for a one-time code, and pushes the result to your browser over a live connection, usually within a few seconds of the sender hitting send.
Free inboxes last 60 minutes and can be extended in 10-minute steps; Pro inboxes last 24 hours. The full technical walkthrough is on the how it works page.
When an inbox expires, a cleanup job permanently deletes the address, its messages and any attachments. There are no backups of expired mail and no way to recover it, which is the point: nothing lingers to be leaked later.
Treat a disposable address as unlisted rather than secret: anyone who knows the exact address while it is live can read the inbox, so never send anything sensitive to one. More in the safety guide and the privacy policy.

BasicsHow it works under the hood, when it helps, and where it will let you down.
A disposable email address is a throwaway inbox that works like a normal email for a short time, then disappears. You can receive messages and verification codes at it, but you never have to reveal your real address. It's ideal for one-off signups, free trials, and any site you don't fully trust with your primary inbox.
Yes. Generating an inbox and receiving email is completely free, with no account required. We also offer an optional Pro plan for people who want longer-lived inboxes, a custom address, several inboxes at once, and an ad-free experience, but the core service stays free forever.
No. A free inbox appears the moment the page loads: no email, name, or password needed. An account is only required if you choose to upgrade to Pro, since billing and your subscription need to be tied to a login.
Free inboxes last one hour by default, and you can extend the timer by 10 minutes at a time directly from the inbox. Pro inboxes last 24 hours. When the timer ends, the address and all of its messages are permanently deleted.
Yes, that's one of the most common uses. When a message contains a one-time code, MailboxTemp automatically detects it and shows it at the top of your inbox so you can copy it instantly without opening the email.
No. MailboxTemp is receive-only by design. Inboxes can accept incoming mail and verification codes, but they cannot send messages. This keeps the service from being used for spam or abuse.
We don't ask for any personal information to use the free service, and inboxes are automatically purged when they expire. Messages are stored only for the lifetime of the inbox. For full details on what we collect and how ads and cookies work, please read our Privacy Policy.
They're gone for good. A background cleanup process permanently removes expired inboxes, their messages, and any attachments from our database and file storage. Expired data cannot be recovered.
We don't recommend it. Because inboxes expire and are deleted, you would lose access to password resets and future notifications. Use a disposable address for throwaway signups and trials, not for banking, work, or anything you need long-term access to.
Yes. You can generate inboxes and read messages programmatically, which is handy for automated testing and QA. One-time codes are auto-extracted in the API response too. The full reference, with endpoints, rate limits, errors, and examples, is in the API documentation.
