Test the email your app sends.
Real inboxes for your test suite: catch signup mails, OTPs and password resets from Playwright, Cypress, CI or an AI agent. Here is a live one, no signup needed.
Setting up your inbox…
A disposable email address in three steps
No account, no app to install, nothing to configure. The temporary inbox above is already yours.
Copy the address
A random temp mail address is ready the moment the page loads. Prefer your own name? Type it and pick a domain.
Use it anywhere
Paste it into any signup, trial or download form. Mail lands in the inbox above within seconds, and verification codes are pulled out for you.
Let it disappear
The inbox and everything in it is deleted after 24 hours. Extend it to seven days if you need longer, or delete it yourself right now.
Temporary email that respects you
Most disposable email services are ad farms with public inboxes anyone can open. This one is built the way we would want it for ourselves.
Private by design
No public inboxes. Your address opens only with a secret link, so nobody can read your temp mail by guessing the name.
Mail arrives live
Messages show up within seconds of being sent, no refresh needed. Verification codes are detected and copied in one click.
Safe to open anything
Every email renders in a sandbox. Scripts never run, tracking pixels are blocked, and links show their real destination.
Your name, your domain
Random address in one click, or type your own username and pick the domain. A private domain pool opens with a free DevDome account.
24 hours, not 10 minutes
Inboxes live a full day by default and extend to seven. Reopen any public inbox from any device by typing its name again until it expires.
Receive-only, no spam cannon
Nothing can ever be sent from an InboxDome address, so the domains stay clean and accepted where other disposable email domains get blocked.
Where a throwaway email address earns its keep
Keep your real inbox for people you know. Use a burner email for everything that only wants your address.
The same inbox, driven from your test suite
Every address on this page can also be created with one API call. Create an inbox, point your app's signup at it, block until the OTP arrives, assert on the message. No sleep(), no IMAP, no flaky mail server in CI.
- Wait for a message or a verification code with one request
- Assert on content, links, spam score and SPF, DKIM and DMARC results
- Signed webhooks, scenarios, bring your own domain
- MCP server so Claude Code, Cursor and other AI agents can test email flows
// 1. a fresh inbox for this test
const inbox = await inboxdome.createInbox();
// 2. your app sends its signup mail there
await page.fill('#email', inbox.emailAddress);
await page.click('text=Create account');
// 3. block until the code lands, then use it
const otp = await inboxdome.waitForOtp(inbox.id);
await page.fill('#code', otp);What you leave behind when you switch
Other disposable email sites

- 24 hours by default, extendable to 7 days
- No ads, no third-party trackers, sandboxed reader
- Receive-only domains that stay clean and accepted

Common questions about temporary email
What is a temporary email address?
A temporary email address (also called temp mail, disposable email, throwaway email or burner email) is a real, working address that exists for a short time and then deletes itself. You use it anywhere you would rather not hand out your personal inbox: signups, free trials, downloads, newsletters and one-time verification codes.
Do I need to sign up?
No. Opening the homepage gives you a working address immediately. There is no account, no password and no email confirmation. A free DevDome account is optional and unlocks the private domain pool and the full API limits.
How long does the inbox last?
A public inbox deletes itself 24 hours after it is created. You can extend it while it is open, up to a maximum of seven days, and you can delete it yourself at any time; after that every email in it is gone and the name is free again. With a free DevDome account, inboxes on the private domains are kept for 180 days. Most 10 minute mail services give you ten minutes; we give you a full day by default.
Can I choose my own username and domain?
Yes. Switch the composer to "Your own username", type the name you want and pick a domain from the list. Random addresses are one click. On the free public domains a name is open to everyone: type it again on any device and the same inbox opens, and once it has expired the name is free to use again. With a free DevDome account the private domains work the other way round: the name is yours alone, nobody else can open it, and the inbox is kept for 180 days.
Can anyone else read my messages?
On the free public domains, yes: those addresses are public. Anyone who types the same name on the same domain opens the same inbox, so use them for sign-ups and downloads, never for anything personal. On the private domains that come with a free DevDome account only your account can open the inbox, and only a hash of its secret is stored, so guessing an address gets an intruder nothing.
Can I send email from a temporary address?
No, and this is deliberate. InboxDome is receive-only, which means it cannot be used to send spam, and the address you hand out cannot be used to impersonate you.
Is it safe to open messages here?
Messages are rendered in a sandboxed frame: scripts in an email can never run, remote images and tracking pixels are blocked until you allow them, and links keep their real destination so you can see it before you click. Links open in a new tab with no referrer passed to the destination.
Can I use this to test the email my own app sends?
Yes. The developer API creates inboxes programmatically, waits for a message or an OTP code, and asserts on delivery, content, links and SPF/DKIM/DMARC results, from Playwright, Cypress, CI or an AI agent through MCP.
Your next temporary email is one click away
Free, private, receive-only. Need it in a test suite? The API uses the same inboxes and the same domains.
