Disposable Email API for Testing & Automation

Best-TempMail API is a disposable email API built for developers, QA teams, CI/CD pipelines, automated testing, and applications that need temporary email infrastructure without maintaining their own mail servers.

Create temporary inboxes, receive real emails, and read messages programmatically through a simple REST API. Getting started takes seconds: the free tier requires no signup and no API key, so you can create an inbox and start testing immediately.

### Key Features

* **Temporary inboxes:** Create random or customized email addresses through the API and control their lifetime based on your plan.
* **Real-time email reception:** Receive incoming messages and access their text and HTML content programmatically.
* **Message waiting:** Use the wait endpoint to hold a connection until new mail arrives, reducing the need for repeated polling.
* **OTP extraction:** Paid plans can automatically identify verification codes from incoming emails, eliminating the need to build custom parsers for different email formats.
* **Webhooks:** Have new-message events pushed directly to your server instead of repeatedly checking for new mail.
* **Developer SDKs:** Official Node.js and Python packages make integration straightforward.
* **MCP server:** Connect the API to AI assistants and MCP-compatible tools such as Claude Desktop, Cursor, and VS Code.
* **OpenAPI support:** Import the API into Postman or Insomnia or use the specification to generate clients for other programming languages.
* **API-first management:** Create, inspect, read, wait for, and delete inboxes entirely through API endpoints.
* **Rate-limit visibility:** Every response includes rate-limit information so applications can monitor their remaining quota and reset time.
* **Webhook security:** Webhook deliveries include HMAC signatures so your application can verify that requests genuinely came from the API.

The API is particularly useful for automated signup testing, email verification flows, QA automation, integration tests, staging environments, CI/CD pipelines, temporary accounts, and applications that need isolated disposable inboxes.

Best-TempMail offers multiple plans so developers can start without committing to a subscription and scale when their automation requires more capacity. The free tier provides 150 requests per hour and up to three inbox creations per day per IP. Paid plans increase limits and add capabilities such as webhooks, OTP extraction, longer-lived inboxes, and attachment downloads.

For developers who simply want to experiment, the keyless free API provides a quick way to test the complete inbox workflow. For production automation, API-key authentication provides private inbox ownership and access to additional capabilities.

Whether you need a lightweight email inbox for a single integration test or disposable email infrastructure for continuous automated testing, Best-TempMail API provides the endpoints, SDKs, and automation tools needed to integrate temporary email directly into your workflow.
