EmailOnDeck vs Tempr.email

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.

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.
