A private guest inbox for quick verification
Guest mode is designed for fast receive-only work: open an inbox, copy the address, read incoming mail, then let expiry or deletion clean up the mailbox.
Short-lived by design
Guest inboxes use 10 minute, 1 hour, or 24 hour windows. Expiry or manual deletion removes the mailbox and its messages.

Disposable email FAQ
How this temp-mail flow works
Is this inbox public like classic public disposable mail sites?
No. A guest inbox is private to the browser and session that created it, using a session token instead of a public inbox listing.
Do I need to sign up first?
No signup is required. The default path is random-first, so you can open the page and start using a temporary inbox immediately.
How long do temp inboxes stay alive?
Guest inboxes use short expiration windows such as 10 minutes, 1 hour, or 24 hours. After expiry, cleanup removes the mailbox and its messages.
When should I switch to a full account?
Use a full account when you need longer-lived mailboxes, outgoing email, APIs, webhooks, or share links for teammates.
