In their own words
EmptyInbox
EmptyInbox provides disposable email inboxes for AI agents and developers through a REST API, an MCP server and a web inbox. A new address can be created for each task or agent run. Messages can be polled, or received through the MCP wait_for_message flow, which can extract verification codes. The web inbox uses passkey sign-in and displays extracted codes and links alongside messages. Each inbox creation uses one credit; receiving, listing and reading messages are free. Messages are deleted automatically after seven days. EmptyInbox receives email only and has no sending endpoint or SMTP credentials. Listed integrations include MCP-compatible agents, OpenAI GPT Actions, LangChain, CrewAI and OpenAPI-compatible frameworks; workflow guides cover Playwright, Cypress, n8n and LangChain. The free plan includes five inbox credits and REST API and MCP access. One-time top-ups start at 1.00 USD for 10 credits, payable by Bitcoin or USDT. The project is open source under the MIT license, and questions go through GitHub issues.
tenmin.app
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.
