Skip the spam.
A fresh single-use email address for every signup. No account, nothing forwards to your real inbox, and it still works when you come back.
Free. No signup. Quick on the web, kept in the app: your key lives in this browser or in your pocket.
Using an agent? Connect it in one tap →One key. Three kinds of signup.
The same addresses and the same codes, whether it is you at the keyboard, an agent working for you, or a product you are building.
Quick on the web, kept in the app
Get an address, paste it, take the code. Keep your key in this browser for the one-off, or in your pocket for the addresses you come back to.
Get an address →Let your agent sign up. Keep your inbox out of it.
Connect ChatGPT, Claude or your browser agent in one tap. It gets its own key, sees codes and links only, and asks you before a new site.
See how it works →The same engine, as an API
Derive addresses, wait for codes, an MCP server and SDKs, your own domains. Addresses are free; you pay per code.
temporarymail.ai →Three steps, no account
Most temp-mail sites hand you an inbox with a timer. We hand you the one thing you came for.
Get an address
One click. We make it from your key and the site you are signing up to, so nothing is stored until mail arrives.
Paste it where they ask
Or let the browser extension fill it in. Every site gets its own address, so a leak points straight at the leaker.
The code shows up here
Big, with a Copy button, or filled into the form for you. Magic links open with one click. The full email is one tap away if you need it.
Still yours when you come back
Every address is made from one key. Same key, same site, same address, so the magic link a site sends next month still lands. Other services solve this with an account that forwards to your real inbox. We solve it with math.
Keep the key in this browser for quick things, or put it in your pocket with the app and your addresses follow you to every device. Lose it and they are gone, which is the point.
Nothing exists on our side until an email arrives. Unlimited addresses cost us nothing, so they cost you nothing.
Let your agent sign up.
Keep your inbox out of it.
Agents stall at "enter the code we sent you", and the usual fix is handing them your real email. Here they get their own addresses, made from your key, under rules you set.
- Codes and links only. The agent never sees the email itself unless you allow it for that address, so nothing in an email can talk to your agent.
- Its own key. Made from yours, so its addresses are yours, listed separately, and switched off with one tap.
- Approvals. Ask before it reads a code from a site it has not used before. A notification, one tap.
- A record. Every signup it made and every code it read, in your app.
Quick on the web. Kept in your pocket.
The website is for the one-off signup. The app is for the addresses you keep coming back to: your key stays on your phone, the code arrives as a notification and copies itself, and the emails you care about stay as long as you want them.
- Your key, locked behind Face ID or your fingerprint, with an encrypted backup you control.
- Every address, code and email in one place, on every device your key is on.
- Plus lives here too: longer history and a private domain no site has ever seen.
Already have a key in this browser? Open the app and scan it across. Nothing to sign up for.
Not a temp inbox. Not an alias.
Temp-mail sites give you an inbox that dies. Alias services give you an account that forwards to your real email. This is a third thing.
| Temp-mail sites | Email aliases | SingleUseMail | |
|---|---|---|---|
| Account needed | No | Yes, with your real email | No |
| The address stops working | After minutes or hours | When you delete it | Never. Same site, same address |
| Touches your real inbox | No | Everything forwards there | No. We never ask for it |
| Shows you the code first | No, an inbox list | No, your usual inbox | Yes, with Copy and Open |
| Follows you to a new device | No | Yes, by logging in | Yes, wherever your key is |
| Your agents can use it | No | No | Yes, codes only, with approvals |
| Pop-ups and redirects | Usually | No | No |
Click the icon. The address is filled. Then the code is too.
The extension spots the email field, fills a fresh address, waits for the code, and drops it into the verification box. No tab switching, no copy and paste.
A notification when the code lands. Already copied.
Your key lives on the phone, so every address you ever made is there, with its codes and emails. Move a key from the browser by scanning it once.
Shipping a product that needs this, for its own agents or its test suite? The same engine is an API and an MCP server at temporarymail.ai, with your own domains and billing. Addresses are free; you pay per code.
Questions people ask
Is it free?
Yes. Addresses and codes are free, and we keep each email for 7 days. Plus keeps emails for 30 days and gives you a private domain no site has ever seen.
What is the app for?
The website is for the one-off signup. The app keeps your key in your pocket, sends each code as a notification, and holds every address you have ever made, on every device.
Can I send email from it?
No. It only receives. That keeps it fast, cheap and out of the spam business.
A site rejected my address. Now what?
Some sites block domains they have seen before. Press New domain and try again; we add fresh ones every day. A private domain on Plus is never on anyone's list.
What if I lose my key?
Your addresses go with it, because we hold nothing that could bring them back. Back it up from Your key, or keep it in the app with an encrypted backup. It takes ten seconds.
Do you read my email?
Our code scans each message once to pull out the verification code or link and show it to you. People do not read them, and free emails are deleted after 7 days.
Can my ChatGPT or Claude use it?
Yes. Open Your agents and choose Connect an agent. The agent gets its own key, sees codes and links only, and you can ask to approve new sites. Switch it off any time.
Which agents work?
Anything that can add an MCP server by its address, which covers ChatGPT, Claude and most agent apps, and any agent that drives your own browser with the extension installed. Phone verification is still the agent's wall; it hands that step back to you.
What do you store?
The emails sent to your addresses, encrypted to a reading key that only your own devices hold, so we cannot read them, and deleted after 7 days (30 on Plus); the extracted code stays readable to us for one hour so your agents can fetch it. Plus a list of your addresses whose labels only your key can open. Never your key, never your real email, never an account, never your IP address. No fonts, scripts or analytics from other companies load on these pages.
How do you make money?
Plus, the API for products, and one clearly marked sponsor on free screens. No pop-ups, no redirects, no selling data. Free stays free.
