freemail

freemail is a Node.js module that provides a programmatic interface to identify whether an email domain is considered 'free' (e.g., gmail.com) or 'disposable' (e.g., mailinater.com). It ships with a database of domains categorized into `free.txt`, `disposable.txt`, and `blacklist.txt`. The package is currently at version 1.7.0. Its primary differentiator is the included, updateable domain database, which can be synchronized from various online sources. However, the project appears to be unmaintained, with its last update several years ago, meaning the included data may be significantly out of date unless manually refreshed by the user. There is no clear release cadence, and new development has ceased.
