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