What is a temporary email address and when should you use one

A temporary email address is an inbox that exists for a short time and then disappears. You get a working address instantly, without creating an account or choosing a password, and you can receive messages on it just like a normal mailbox. When the timer runs out, the address and everything in it is deleted. People also call this temp mail, a disposable email address, a burner email, or a 10 minute email.

The idea is simple: not every website deserves your real email. Many sign-up forms ask for an address just to send you a single confirmation link, yet that address then ends up on marketing lists, gets shared with partners, or leaks in a data breach years later. A temporary inbox lets you complete the step you need without handing over a permanent way to reach you.

How a temporary inbox works

On Mailiffy, an address is created the moment you open the page. It looks like any other email address, for example sunny.panda88@mailiffy.online. When someone sends mail to it, our mail server receives the message and stores it in a private inbox that only your browser holds the key to. The page checks for new messages every few seconds, so a confirmation email usually appears almost as soon as it is sent.

Each inbox starts with a 10 minute countdown. If you need a little longer, you can add time in 10 minute steps, up to an hour in total. When the countdown ends, the address and all of its messages are permanently removed from our database. There is nothing to cancel and no account to close.

Good times to use a temporary email

Downloading a free resource. Ebooks, checklists, and whitepapers are often gated behind an email form. A disposable address gets you the download link without signing you up for a weekly newsletter you never asked for.

Trying a new app or service. If you only want to see what a product looks like before committing, a temporary address lets you explore without tying the trial to your identity.

Public Wi-Fi and one-time forms. Cafés, airports, and event registrations frequently ask for an email address just to let you in. That is exactly the kind of address that tends to attract spam.

Testing your own website. Developers and marketers use temporary inboxes to check sign-up flows, password reset emails, and welcome messages without filling their own inbox with test mail.

When you should use your real email instead

A temporary email is the wrong tool for anything you need to keep. Do not use one for banking, shopping accounts with saved payment details, government services, work tools, or any account you might need to recover later. Password resets are sent to the address on file, and once a disposable inbox is deleted, nobody can receive that reset email, including you.

You should also avoid sending sensitive information to a temporary address. Anyone who knows or guesses an address can send mail to it, so think of it as a short-lived public mailbox rather than a secure vault. Mailiffy is also receive-only: you cannot send or reply from it.

Is it allowed?

Using a temporary email address to protect your privacy is legal in most places and is a normal part of good digital hygiene. What matters is how you use it. Creating fake accounts to abuse a service, evade bans, or commit fraud is against our terms and against the rules of most websites. Some sites also block disposable domains entirely, in which case you will need a different address.

The bottom line

Think of a temporary email as a privacy shield for low-stakes moments. It is quick, free, and keeps your real inbox clean. For everything important, use an address you control for the long term. When you need a throwaway inbox, you can get one on the Mailiffy home page in a couple of seconds.
