How it works
Take an address
One is already waiting above. Copy it and paste it wherever a signup form is asking.
Receive mail instantly
Messages appear in under a second. Verification codes are pulled out and shown on their own so you can copy one without opening anything.
Messages clear themselves
Mail is held for 24 hours and then deleted. The address itself stays yours for as long as you keep using it.
Built for test suites
Sub-second delivery
Mail lands before the page finishes reloading.
A real API
Three GET endpoints, sold through RapidAPI with a free tier.
Nothing retained
Messages are deleted after 24 hours, not archived.
Raw source access
Read full headers and the raw message when a test needs them.
Is your email landing in spam?
Send one email to a test address and get a scored report on your SPF, DKIM, DMARC and sender DNS, with a fix for each problem. Free, no signup.
Run a free testAPI
Still testing signup emails by hand?
Every signup flow you test needs a verification code, and reading it yourself does not scale past the first run. Three GET endpoints give your suite an address, its inbox, and the message body — so the test that waits on an email can just read it.
- Addresses never expire. Pin one to a fixture and reuse it for years instead of regenerating before every run.
- Two headers, no SDK. Send x-rapidapi-key and x-rapidapi-host from any language that can make an HTTP request.
- Safe bodies by default. HTML renders in a sandbox and attachments download as inert files, with the text part alongside the HTML.
- Free tier, no card. Subscribe on RapidAPI and call it today; paid plans only raise the request quota.

What is a temporary email address?
A short-lived inbox created for quick sign-ups, downloads, and verifications.
Is temp mail safe?
It is safe for low-risk use such as testing services or claiming offers, but not for banking or government logins.
How long do temporary emails last?
Your address is permanent. Messages are kept for 24 hours, extended each time new mail arrives, up to seven days.
Can I receive verification emails with temp mail?

Why do some websites block disposable email addresses?
Some sites block them to reduce abuse, fraud, and mass account creation.
