A fake email, also called a disposable email, temporary email, throwaway email, or burner email, is a real, working inbox that receives mail for a short period of time and is then automatically deleted. You hand it out instead of your real address whenever you do not want a sign-up, verification flow, or marketing list reaching your primary mailbox.
Fake Email gives you one in under a second at @fake-email.site, with no registration, no captcha, and no tracking. Use it for disposable email signups, one-time codes, QA automation, or anywhere a real address is overkill.
A free temporary email service designed for developers, QA engineers, and privacy-minded users who need a clean inbox for one-off signups.
Generate a new temporary email address in under a second. No registration, no captcha, no waiting room.
Incoming messages appear in the inbox within seconds of arrival, including attachments and HTML bodies.
No accounts, no analytics fingerprinting, no third-party trackers loading on inbox pages.
REST endpoints for creating mailboxes and polling messages. OpenAPI 3.1 spec for client codegen.
Rust SMTP server and HTTP service available on GitHub. Audit the code, self-host, or fork it.
Mailboxes are ephemeral — when they expire, all messages, attachments, and metadata are deleted.
Three steps. Total time to first inbox: under one second.
Click Generate or pick a username. A new mailbox at @fake-email.site is yours instantly.
Paste the address into a signup form, a CI test fixture, or any place that needs to send you a verification code.
The inbox polls in real time. Click a message to read it. Mailboxes expire automatically.

Trial a SaaS product, claim a coupon, or download a whitepaper without inviting newsletters into your primary inbox.
Get the OTP or confirmation link, copy it, and walk away. The mailbox is gone before any marketing email arrives.
Drive automated tests that need a unique inbox per run. Hit the REST API directly — no scraping required.
Use a disposable address on forms you suspect will sell, share, or leak your contact information.
Get past mandatory email verification on file hosts, forums, and download walls without committing a real address.
Many airports, cafes, and hotels gate Wi-Fi behind an email address. A disposable inbox satisfies the form and dies on its own.
