Summary

Mailinator provides temporary inboxes and email and SMS workflow testing for developers, QA teams, and businesses. Teams can use it to check delivery for OTP, MFA, onboarding, password recovery, and other email workflows at scale. Subscriptions include private testing domains, where messages can be received at any address without setting up an inbox first. Its REST API retrieves inboxes, messages, and SMS; it can also inject messages and connect with CI/CD pipelines. Inbound webhooks accept HTTP POST messages from sources such as alert systems, Zapier, or Twilio, with configurable rules. SMS can be routed to an inbox or API for automated OTP and 2FA checks. Public inboxes are readable by anyone, and their messages typically auto-delete after several hours; Mailinator is receive-only and cannot send email or fill out forms. The public plan is free, and Business pricing starts at $79/mo (annual). A two-week Business trial is listed. Paid plans include private domains, storage, and usage limits that vary by tier.

Who it is for

It suits developers, QA teams, and businesses testing email or SMS workflows, especially where API or CI/CD integration is useful. Public inboxes are for messages that do not require privacy.

Free public inbox plan

What to know first

Verdict

Mailinator is built around receiving and testing email and SMS rather than sending messages. Its public inboxes are free, but private testing domains and higher usage allowances are covered by subscription plans.
