About the service
About OneTempMail · Free Temporary Email Service
A disposable inbox you can use without an account, without a phone number, and without handing your real address to a service you may never use again.
What OneTempMail is
OneTempMail is a free temporary email service. You open the site, you get a working inbox in a fraction of a second, and any message sent to that address shows up in the browser within seconds. There is no signup, no password, no profile, and no link to your real identity.
The service is built for one job: receiving short-lived mail. Sign-up confirmations, one-time passcodes, download links, forum verifications, trial activations. When you are done, you close the tab and the address stops mattering. The inbox is wiped on a short rotating schedule so nothing lingers on the server.
Why we built this
Every product on the internet now asks for an email address before it will tell you what it does. Most of those addresses end up rented, traded, breached, or quietly piped into a newsletter you never agreed to. Real inboxes get noisier every year because of that pattern.
OneTempMail started in 2023 as a side project to give people a clean way out of that loop. The goal has not changed: a simple, fast, ad-supported disposable inbox that you do not have to trust with anything personal, because we do not ask for anything personal.
How we make money
OneTempMail is free to use and supported by display advertising. We want to be explicit about what that means and what it does not mean.
- We show ads served through standard ad networks. They pay the servers, the bandwidth, and the people who keep the lights on.
- We do not sell user data. There is no audience export, no data broker pipeline, and no paid integration that reads your inbox.
- We do not sell or share message content with advertisers. Mail bodies are never used to target ads on this site.
Our privacy promise
We try to make promises that you can actually verify, not slogans. Each item below points at something concrete in how the service is built.
- No account, no profile. There is no user table to leak. We do not ask for a name, phone number, recovery email, or payment method.
- Short retention by design. Inboxes and messages are deleted on a short rotating schedule. The service is built for ephemeral mail, not archival storage.
- No mail content scanning. We do not read, index, profile, or model the body of your messages for advertising or analytics.
- Minimal application logs. The application does not persist visitor IP addresses alongside inbox content. Edge providers may keep short-lived request logs for abuse prevention, as is standard.
Who runs OneTempMail
OneTempMail is an independent project, not part of a larger brand. The service has been running publicly since 2023. You can reach the team directly at the address below for press, abuse reports, takedown requests, or general questions.
Open standards we support
OneTempMail tries to be a good citizen of the open web. We publish machine-readable signals so other tools, search engines, and AI agents can understand the site without scraping it blind.
- RFC 8288 (Web Linking). Typed relations on links so clients can follow next, prev, canonical, and alternate references reliably.
- RFC 9727 (.well-known URIs). Discovery endpoints under /.well-known/ so agents can find capabilities without guessing URLs.
- Content Signals. Explicit signals about how site content may be used by automated crawlers and training systems.
- Agent skills discovery. A published skills surface so AI agents can call the temporary inbox in a structured, predictable way.
