Trashmail-Blacklist.org is a temporary email domain detection service aimed at developers. Its core goal is to block disposable email addresses before they enter your database. The site claims to offer a free REST API covering 80,000+ known trashmail providers, suitable for registration forms, contact forms, and account creation flows. After a user enters an email address, the system can typically extract the domain and call the API to determine whether it is blacklisted.
Its biggest strength is simplicity: no registration, no API Key, and a single GET request is enough to query a domain. Available endpoints include /check/json/{domain}, /check/xml/{domain}, /check/yaml/{domain}, and /check/img/{domain}, with response formats covering JSON, XML, YAML, and image-based status. The site provides examples for curl, Python, JavaScript, PHP, and Go, showing that any language or framework capable of making HTTP requests can integrate with it. Domain detail pages also display status, date added, last checked time, reason for listing, MX records, and related domains, with support for false-positive feedback.
The currently crawled content clearly states Free REST API, No Signup Required, and No API key required. No paid plans, request limits, payment methods, or SLA were found. In terms of documentation, the endpoints, response examples, and Playground are clear enough for basic integration. However, information on error codes, rate limits, uptime commitments, data update policies, privacy, and enterprise support is limited.
The advantages are very low integration cost, flexible response formats, and no authentication requirement, making it suitable for quickly adding disposable email blocking to a product. The drawbacks are that it does not state whether it is open source or supports self-hosting, and there is no official SDK. The statistics section shows No data available, so data transparency is limited. While free unauthenticated access is convenient, it carries higher risk for businesses with high concurrency, compliance auditing, or strict stability requirements.
It is best suited to small and medium-sized web apps, independent developers, internal tools, and registration systems that need low-cost anti-abuse protection. It is less suitable for enterprise-critical workflows that require a clear SLA, private deployment, or contract-based support. The crawled text does not provide information about access from mainland China, so availability should be treated as unknown. If network or payment restrictions are a concern, alternatives include Kickbox, MailboxValidator, Abstract, ZeroBounce, or maintaining your own disposable email domains blacklist.
