Mailinator vs Tempr.email

Mailinator provides temporary inboxes and tools for testing email and SMS workflows. Developers, QA teams, and businesses can use it to check delivery for OTP, MFA, onboarding, password recovery, and other email processes at scale. Paid subscriptions include private testing domains, where messages can arrive at any address without creating an inbox first. The REST API retrieves inboxes, messages, and SMS, injects messages, and connects with CI/CD pipelines. Inbound webhooks can accept HTTP POST messages from sources such as alert systems, Zapier, or Twilio, then apply configured rules. SMS can be routed to an inbox or API for automated OTP and 2FA testing. The free public inboxes are readable by anyone, and messages typically auto-delete after several hours. Mailinator is receive-only: it cannot send email or fill out forms. The Public - Free plan is free to use without sign-up. Business costs $79 a month billed yearly; a two-week Business trial is listed. Other plans include Verified Pro at free, Business Plus at $159 a month billed yearly, and Enterprise at a price agreed with the maker with custom pricing.

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.
