About mail.cx
mail.cx is a temporary email service that keeps spam away from your real inbox — and an email testing platform built for developers. We provide short-lived inboxes, API access, and real-time mailbox events for modern application workflows.
What We Do
We help developers, QA teams, and product teams test account verification flows, transactional emails, notification pipelines, and application integrations in a simple and reliable way.
mail.cx combines instant inbox creation, web-based email receiving, custom domains, API tokens, and real-time event delivery to support both individual developers and production-grade team workflows.
Our Goal
To make email testing for software products and developer tools easier, faster, and more secure.
Privacy & Security
We take privacy seriously. The inbox, email view, dashboard and sign-in screens show no ads and load no tracking, analytics or advertising scripts; some marketing and content pages may show Google AdSense ads. All connections are encrypted via TLS, and passwords and API tokens are stored only as hashes. For full details, see our Privacy Policy.
