Mail.cx vs Tempr.email

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.

Tempr.email provides disposable email addresses for receiving messages without giving out a personal inbox address. Users choose an alias and domain, then read incoming mail without registering. The service lists 61 domains, with more added regularly, and accepts text and HTML email, including file attachments. Messages are automatically deleted after 30 days, though users can delete them sooner. A free account adds password protection for selected mailboxes, custom domains, saving or printing messages, header viewing and bookmark access. Premium access enables sending, forwarding and replying, as well as RSS and ATOM notifications for new mail. Tempr.email is a web service that also works in a responsive mobile browser. Listed use cases include registrations, downloads, surveys, short-term test accounts and newsletter testing. The service advises using a regular address for banking and important long-term accounts. It cautions that complete anonymity cannot be guaranteed, and that mailbox security partly depends on alias guessability; password protection also has limits. The free plan costs nothing and retains messages for 30 days.
