Frequently Asked Questions

Each address is valid for 10 minutes by default. You can extend it with the “+10 min” and “+1 h” buttons — up to 24 hours in total. Once it expires, the address and all received messages are deleted automatically. You can generate a fresh address any time with the “New address” button.

No. The address is generated instantly when the page loads – without any signup, password or personal data.

Yes, 10MinMail is completely free.

No. Temporary addresses are meant for receiving messages only, for example confirmation links or one-time signups.

Using it requires no personal data. However, never use a disposable address for important or confidential accounts (e.g. banking), because the inbox is in principle accessible and gets deleted after it expires.

Yes. Temporary email addresses are a legitimate tool to protect your privacy. As always, only misuse for illegal purposes is prohibited.

10MinMail owns an email domain and accepts mail for randomly generated addresses on it. When someone sends a message to your temporary address, it is routed to our server and shown in the inbox on the page within seconds. There is no account and no login — the address only exists in your current browser.

Yes. Addresses are generated randomly by default — a random handle cannot be guessed by others — but you can type any handle (the part before the @) into the “Reopen an inbox by handle” field to open that address, whether it's one you used before or a brand-new one you just made up. Keep in mind: anyone else who knows the handle can open the same inbox, so random handles are the safer choice.

Yes. While the address is active, click “+10 min” or “+1 h” next to the countdown to extend its lifetime — as often as you like, up to a maximum of 24 hours from creation. An address that has already expired cannot be revived; in that case generate a fresh one.

Yes. Your address lives in a cookie in your browser, so as long as it hasn't expired you can close the tab, come back, and find the same address with all its received messages. On another device, or after the cookie is gone, type the address's handle (the part before the @) into the “Reopen an inbox by handle” field to get back to it.

The most common reasons: the sender simply takes a few minutes to deliver, the address was typed with a mistake, the address had already expired when the mail was sent, or the website blocks disposable email domains. Keep the page open — the inbox refreshes automatically every few seconds.

Yes, a few services maintain blocklists of known disposable email domains and reject signups from them. If that happens, the site wants a long-term relationship with you — decide whether it deserves your real address or whether you skip it.

The messages are gone: once the address has expired, everything it received is deleted and cannot be restored. The address itself, however, can be reopened at any time — type its handle into the “Reopen an inbox by handle” field and new mail sent to it will arrive there again.

As many as you like. Every click on “New address” gives you a fresh, independent inbox for another 10 minutes, free of charge.

Typical uses: one-time signups, downloads behind email gates, free trials, testing your own signup flows, and Wi-Fi portals that demand an email address. Never use it for banking, shopping orders, or any account you'll need to access or recover later.
