In their own words
Mail.cx
Mail.cx provides short-lived inboxes for developers, QA teams, and product teams checking account verification, transactional messages, notification pipelines, or application integrations. It only receives email; it does not send it. A web inbox can be opened without signup by choosing a username or generating one, and server-sent events can push arriving mail to the browser. Its REST API supports long-polling, retrieval of parsed or raw email, attachment downloads, and event delivery. API use is limited to 10 requests per second per token; long-polling allows one concurrent wait per token and 10 per address. Free messages are automatically deleted after one hour, while Pro messages are retained for 72 hours. The Free plan is free, and Pro is $9.90 a year. A separate pricing note lists paid plans from $4/mo. Mail.cx says connections use TLS and that passwords and API tokens are stored as hashes. Its terms caution that message retention and recovery are not guaranteed, and advise against relying on the service for critical, sensitive, or business-essential communications.
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.
