Best Temp Mail API

Best-TempMail Developer API is a disposable email API built for developers who need temporary inboxes for testing, automation, QA, and privacy-focused workflows. It provides a simple REST API for programmatically creating temporary email addresses, receiving incoming messages, reading message contents, managing inboxes, and working with available email domains.

The API makes automated email testing straightforward without requiring developers to build and maintain their own disposable mailbox infrastructure. Developers can create inboxes, retrieve incoming messages, access text and HTML content, manage inboxes, and delete them when they are no longer needed.

Best-TempMail offers a free, keyless tier with 150 requests per hour, allowing developers to start without an account, API key, or payment card. All API endpoints and real-time WebSocket delivery are included in the free tier, along with commercial use.

For developers who need higher limits, the Founders plan offers launch pricing of just $19.99/year for the first 100 developers, compared with $19.99/month on the standard Developer plan. Founders subscribers get 2,000 requests per hour, an API key, unlimited inbox creation, all API endpoints, real-time WebSocket delivery, and commercial use. Most importantly, the Founders rate is locked while subscribed, giving early users long-term pricing protection.

The API is useful for QA engineers, developers, automation specialists, and teams testing signup flows, email verification, OTP delivery, password resets, notifications, CI/CD workflows, and other email-dependent applications.

All endpoints return JSON and include documented rate limits, request IDs, error responses, and health-check functionality.
