10 Minute Mail vs Mail.cx

10 Minute Mail provides disposable email addresses for website sign-ups, letting you receive messages without sharing your regular address. Incoming mail appears automatically on the webpage, where you can read it and open links; replies and forwarding to a personal account are also supported. An address expires after 10 minutes, and its countdown can be reset for another 10 minutes. You do not need to register or provide information to get an address. The free plan costs nothing and includes a temporary address with the resettable timer. The service lists Android, iOS, and web platforms, along with custom domains and attachments; inbox protection is listed as none. Its security information says session data and email stay in RAM, are erased when the session ends, and are protected in transit with HTTPS/TLS. The privacy policy also says it may collect usage details such as IP address, browser information, visit times, and pages visited, and describes third-party tracking and advertising cookies. The FAQ advises against using it for important accounts that may need password resets because the address expires.

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.
