About mail.gw

Mail.gw provides a REST API for creating and managing temporary, disposable email accounts, intended for automating email confirmation steps during testing and site registrations. Accounts are created against a set of API-provided domains, then authenticated with a bearer token obtained via a token endpoint; the API also exposes endpoints for listing and retrieving domains, managing the account resource (get, delete), and fetching received messages. No API key is required, and the general rate limit is 8 queries per second per IP address.

The service is aimed at developers who need to automate account signups that require email verification, and is documented using the OpenAPI Specification v3, with a downloadable spec and an interactive testing interface. It is API-compatible with the Mail.tm API, differing only in base URL, and lists a Dart client library as an available integration.

Usage is restricted to sites the user has permission to register on, and the terms prohibit illegal activity as well as building competing paid temp-mail products that rely exclusively on the API.
