POSTBOX — GENERAL DELIVERY
Est. for the age of the sign-up form

An address that exists just long enough to matter.

Postbox hands you a working inbox for ten minutes — long enough to catch a verification code or a one-time download link, and not one minute longer. No account, no real name, nothing left behind.

How the delivery works

01 / ISSUE

An address is issued

The moment you land here, Postbox assigns a random address on our domain. It's yours the instant it appears — no form, no email of your own required to get one.

02 / RECEIVE

Mail arrives in view

Give the address to whatever site or form asked for one. Anything sent to it shows up right here in the inbox below, usually within a few seconds.

03 / EXPIRE

It lets go on its own

Ten minutes after it's issued, the address and everything sent to it are gone for good. Need more time mid-task? One tap adds another ten.

Notes from the sorting office

Why a disposable address, at all

Most forms on the internet ask for an email address before they'll let you past the front door — a newsletter you'll never read, a download that wants "just your email first," a forum you're joining to ask one question. Handing over a real inbox for a one-time interaction means trading a little bit of your attention, indefinitely, for something you needed for thirty seconds.

A disposable address flips that trade. You get the verification code or the confirmation link you actually came for, and the address itself never becomes a place anyone can reach you again. There's no password to lose, no account to close later, and nothing tied to who you are.

What it's built for

Testing what a signup flow looks like before committing a real account. Reading a single confirmation email. Trying a service you're not sure you'll keep. Keeping a forum thread's replies out of your main inbox. Anywhere a site demands an email just to let you look around.

What it isn't built for

Anything you'll need to get back into later — password resets, banking, work accounts, or any service where losing access to the inbox means losing access to the account. Ten minutes is the whole point; plan around it rather than against it.

Questions that come back to us

Do I need to sign up to use this?

No. An address is generated the moment the page loads. There's no account, no password, and nothing to remember for next time — because there won't be a next time with the same address.

What happens after ten minutes?

The address stops receiving mail and everything that was sent to it is deleted. If you're still mid-task, press "+10 min" before the clock runs out to keep the same address alive.

Can I send mail from this address?

No — Postbox only receives. That's a deliberate limit: an address that can send mail can also be used to spam or impersonate, and that's not what this is for.

Can I get a permanent address instead?

Not through Postbox. If you want a lasting address on your own domain, that's a separate, ordinary email setup — this tool exists specifically for the throwaway case.

Is anything about the mail stored after it expires?

No. Once an address expires, its messages are removed from storage — they aren't archived, backed up, or kept for any purpose afterward.
