10 minute mail vs this inbox
10 minute mail is a well-known product name for a disposable mailbox with a ten-minute life. Temporary Email is an alternative: same use (signups, verification, one-off forms), a real receiving address, and an on-page inbox. The difference is the clock. After five minutes the address and messages are deleted.
If a site is slow and the five minutes run out, start a new inbox from this page and paste the new address. There is no extend button. That is intentional — this is not a private account and not a place to store mail.
Why not ten minutes
A longer public inbox collects more stray mail and stays readable by anyone who knows the address. Five minutes covers one-time codes for most forms. If you specifically need a ten-minute window, another service may fit better; if you need a code now, use the widget above.
Guerrilla Mail and YOPmail keep mail longer. This site does not compete on lifetime. It competes on being free, instant, and gone.
How to use it
When the address shows, copy it into the form that asked for email. Watch this tab. If you are in the queue, leave the tab open until the mailbox is created.
Do not use 10 minute mail (or this 5 minute stand-in) for accounts you must keep, password resets next week, or anything confidential. Anyone who knows the live address can read mail until it expires.
