About mail.tm

Mail.tm is a REST API for creating temporary, disposable email accounts and receiving messages sent to them. It supports the full lifecycle through API calls: retrieving available domains, creating an account with an address and password, obtaining an authentication token, and fetching received messages. Messages can be retrieved through polling or in real time via SSE.

The API requires no API key and no signup to begin using it, and has no paid tiers. It is rate-limited to 8 queries per second per IP address. It follows the OpenAPI v3 specification, with both a downloadable spec and interactive documentation available.

Usage terms prohibit illegal activity, reselling the API as a paid product, and running proxy or mirror services under a different domain. Attribution linking back to mail.tm is required for API usage. The service is suited for developers who need disposable email addresses for tasks such as testing sign-up flows that require email confirmation.
