About MailboxTemp
MailboxTemp is a free disposable-email service. It gives you a temporary, anonymous inbox the moment you open the page so you can receive verification codes, confirmation links, and one-off messages without handing your real address to every website that asks for one.
Why we built it
Almost every app and website now demands an email address before it will let you do anything — read an article, download a file, claim a trial, or join a community. Each of those addresses becomes another entry in a marketing database and another account that can leak in a data breach. We built MailboxTemp because we wanted a fast, no-friction way to satisfy that "please verify your email" step without polluting our real inbox or risking our privacy.
The whole experience is designed around one idea: you should be able to receive an email in seconds, copy the code you came for, and walk away — with everything deleted automatically afterward.
How the service works
When you load the site, we generate a random inbox on one of our domains and show it to you immediately — no signup, no password, nothing to install. Any message sent to that address appears in your browser in real time over a live connection. If a message contains a one-time passcode (OTP) or verification code, we detect it automatically and surface it at the top of the inbox so you can copy it in a single tap.
Free inboxes live for one hour and can be extended in ten-minute steps. When the timer runs out, the address and every message in it are permanently deleted from our servers. MailboxTemp is receive-only — you cannot send email from it — which keeps the service from being used for spam or impersonation.
What MailboxTemp is good for — and what it isn't
It's ideal for throwaway signups, free trials, downloads, forum registrations, and any verification flow where you don't need the account long-term. It is not a place to register accounts you'll need to recover later: because the inbox expires, you would lose access to future password resets. For banking, work, or anything important, use your real address.
Privacy & data
We don't ask who you are. Creating an inbox requires no name, no personal email, and no account. Messages exist only for the life of the inbox and are then erased. For the full details on what we collect and how we handle it, see our Privacy Policy and Terms of Service.
