What is Tempx?
Tempx is a free temporary email service. It gives you a real, working email address that you use for a short time and then discard, ideal for confirmation links, verification codes and testing, without giving out your personal address.
The address is fully functional: messages arrive within a few seconds. When you are finished, close the tab, everything is removed automatically.
Email testing, built in
The same inboxes double as a test bench: real mail, no mail server to run, and nothing ever delivered to a real person.
Email testing
Signup, verification, OTP and password-reset flows, asserted against the real message.
SMTP testing
Capture your app's outgoing mail in a sandbox inbox instead of a real mailbox.
For QA & automation
Read inboxes from Playwright, Cypress, CI or plain curl over a free API.
For AI agents
Give Claude or ChatGPT a scoped, revocable inbox over MCP.
Built for AI agents
Your coding agent or automation can have its own inbox. Tempx ships a scoped MCP server with browser pairing, so agents receive verification links and read mail directly, no forwarding by hand.
Reading first, sending captured
List, open, search and wait_for_email for reading. The optional send permission composes mail that is captured in the same inbox for testing, never delivered to anyone.
Scoped, revocable tokens
Each connection is limited to a single inbox, expires on your schedule, and can be revoked in one click. Only a hash of the token is stored.
Works with Claude, ChatGPT & Z.ai
Claude Code and ChatGPT connectors pair through your browser, no token to paste. Z.ai and any other MCP client can use a Bearer token from the account page.
Quick setup:
SMTP capture for developers
Testing an app that sends email? Point it at the Tempx SMTP gateway instead of real users, verification links, password resets and notifications are captured in your inbox for inspection.
Receiving vs sending, in one sentence: A Tempx address receives real email from anyone, any sender, any domain, anywhere. Sending is testing-only by design: mail submitted through the SMTP gateway is never delivered to the outside world; every message is captured into the inbox your credentials point at, ready to inspect.
Standard SMTP, nothing to install
Set your app's mail settings to smtp.tempx.uk, port 587 with STARTTLS. Any language or framework with an SMTP client works out of the box.
Credentials tied to one inbox
Create SMTP credentials in your Tempx account, a username and a password shown once. Captured mail is delivered to the credential's paired inbox and can be revoked at any time.
Captured, never delivered
The gateway is a capture trap: every message is accepted and stored, and nothing is ever forwarded onward, a test run can never email a real person.
How it works
Three steps, no account:
- Get an address. Pick any name for your inbox, or use a private random address instead. It works the moment you choose it; see it at the top of this page.
- Use it. Paste the address into a form, or send a message to it from another account. Email arrives in your Tempx inbox.
- Read and move on. Open the message you need. Everything is removed automatically after the retention period, or delete it yourself.
Why people use temporary email
Keep your inbox clean
Sign-ups, trials and downloads often lead to weeks of marketing email. A temporary address absorbs it instead of your main account.
Reduce your exposure
The less your primary address is spread across the web, the less it turns up in data breaches and marketing lists.
Test and develop
Developers and QA teams use disposable addresses to test registration, password-reset and notification email.
One-time reads
Sometimes you need one link or code, once. A throwaway inbox is the quickest way to receive it.
What people use it for
A disposable inbox fits any interaction that should not outlast the task. The most common ones:
One-off downloads
Whitepapers, templates and "enter your email to continue" gates, get the file, skip the follow-up.
Trials and betas
Test a service properly before deciding it deserves a place in your life, and in your real inbox.
Gaming accounts
Spare accounts for games and platforms you are not ready to attach to your main identity.
Local selling
Marketplace buyers get a working address you can abandon once the item is sold.
Wi-Fi and kiosks
Café, hotel and airport gates that insist on an address before letting you online.
Keeping options open
Sign up now, decide later, if the service turns out noisy, nothing of value was lost.
Temporary email vs your regular inbox
Neither replaces the other, they solve different problems:
| Temporary inbox (Tempx) | Regular inbox | |
|---|---|---|
| Sign-up | None, open and use | Account and password |
| Lifetime | Minutes to days, then auto-deleted | Years |
| Sending | Receive-only by design | Full send and reply |
| Best for | One-off codes, trials, tests | Real correspondence |
| If it leaks | Nothing worth stealing | Reset links, history, identity |
What to know before you use it
Temporary email is short-lived and not confidential. Do not use a Tempx address for anything important or sensitive.
- Tempx is receive-only, you cannot send email or reply.
- Messages are permanently deleted after the retention period shown in the app (7 days for a named inbox, 1 hour for a random one). Deleted mail cannot be recovered.
- Do not use it for banking, government, work or school accounts, or for password recovery / two-factor codes you may need later.
- Email is not private in transit, and a named inbox is readable by anyone who knows its name. Treat anything sent to a temporary address as potentially readable by someone else.
- Using disposable email to evade bans, abuse services or break the law is not allowed, see our Terms.
Common questions
- Is Tempx free?
- Yes. Tempx is free to use and needs no account.
- How long do messages last?
- Messages in a named inbox are kept for 7 days; in a random private inbox, 1 hour. The current retention period is always shown in the app.
- Can I pick my own address?
- Yes, type any name and open that inbox. It is public: anyone who knows the name can read it. For anything sensitive, use a random private address instead.
- Can I send email with Tempx?
- No, nothing is ever delivered to a real recipient. Developers can point an app at smtp.tempx.uk, where test sends are captured for inspection (Mailtrap-style) instead of delivered.
