FreeCustom.Email

FreeCustom.Email is an API-first email testing platform built for developers and QA teams to automate signup, OTP, and authentication workflows.

It enables teams to create inboxes programmatically, receive emails in real time, and extract verification codes or magic links without manual parsing. This makes it easy to test email-based flows such as account verification, password resets, and multi-factor authentication in a reliable and CI-friendly way.

Unlike traditional temporary email services, FreeCustom.Email is designed specifically for automated testing and developer workflows. With support for REST APIs, WebSockets, SDKs, and CLI tools, it integrates seamlessly into modern testing environments including Playwright, Cypress, and CI/CD pipelines.

The platform focuses on reliability, speed, and scalability—helping teams eliminate flaky email-based tests and build deterministic authentication testing workflows.
