In their own words
EmailOnDeck
EmailOnDeck provides temporary email addresses for sign-ups, confirmations, and privacy protection. A free address typically remains available for hours, often most of the day, but closing the browser or clearing cookies can end access sooner. Free users can send messages only to other EmailOnDeck addresses; Pro users can send anonymous email to anyone. Messages support viewing or downloading attachments. Chrome and Firefox extensions create disposable addresses, and free iPhone and Android apps are available. The browser-based Spy Pixel Scanner says pasted email source stays on the device rather than being uploaded or stored. Pro API access covers address creation and deletion, domain lists, message counts, headers, and raw messages, with a documented limit of 25,000 calls per day; sending through the API is unavailable. API use requires an active Pro account and a 40-character private key. Plans include an ad-supported free option and Pro payments listed at 0.00 BTC or 0.03 ETH, each extending access for 30 days.
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.
