Temporary mailbox
A temporary mailbox is your short-term PO box on the web: a place mail can land for a while, then close up entirely. MailboxTemp opens one for you instantly, no key, no lease, no paperwork.
What is temporary mailbox?
A temporary mailbox is a self-expiring inbox. Mail arrives, you read it, and when the timer runs out the whole mailbox — messages and all — is permanently removed.
A real example
Receiving a one-off attachment or a confirmation you only need to glance at? A temporary mailbox holds it just long enough, then cleans itself out so nothing accumulates.
How temporary mailbox works on MailboxTemp
- Open MailboxTemp — a temporary mailbox address is waiting the moment the page loads.
- Copy it and paste it into whatever form is asking for an email.
- Messages arrive live; any one-time code is pulled out and shown at the top.
- When the timer runs out, the inbox and its contents are permanently erased.
Good to know
Everything in a temporary mailbox is deleted at expiry, so save anything you actually want to keep before the timer ends.
