RapidInbox was built to solve a simple problem: developers need a reliable, fast, and programmable way to test email workflows.
We believe that testing email shouldn't be a hassle. Whether you're verifying sign-up flows, testing newsletter rendering, or automating QA processes, you need a tool that just works.
That's why we built RapidInbox with a focus on speed, API-first design, and privacy. No login required for basic use, and powerful features for power users.
