What it is

tenmin.app is a free temporary email service for receiving messages without creating an account. It gives you an address that lasts ten minutes; the address and its messages then expire. The Extend button resets the inbox timer for another ten minutes, and the service states no hard cap on extensions. It is intended for one-time signup codes, confirmation links, download links, and testing email-sending systems. The inbox is receive-only: you cannot send or reply, and forwarding is not configured by default. A read-only API retrieves inbox messages. Messages have a 600-second time-to-live for automatic deletion. Incoming HTML is sanitized and shown in a sandboxed iframe, although remote images may load. Attachments can be received, but previews are unavailable and downloading is limited. The privacy policy says IP addresses are not logged against inbox IDs, browser fingerprints are not stored, and message contents are not sold or shared. Inbox IDs are public to anyone who knows or guesses them.

Strong points

  • Read-only API for retrieving messages
  • Automatic deletion after 600 seconds
  • Privacy policy limits logging and sharing

Limits

Who it suits

It suits people needing disposable inboxes for one-time signups, links, or email-system testing. It is not intended for high-stakes use because inbox IDs are public.

Verdict

tenmin.app provides short-lived, receive-only inboxes through the web and API at no cost. Its public inbox IDs and limited attachment handling make it a poor fit for sensitive or ongoing correspondence.
