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
