freemail

A database of free and disposable
email domains and a handy Node.js module for querying it.

Use the Node.js module or access the files in the ./data directory and parse
with your language of choice.

In an effort to create the most up-to-date list of domains, the database can be
synchronized with various lists from around the web. You can also add new
domains directly by opening a pull request.

Database

There are three key data files in this project:

• free.txt contains a list of domains that are known to provide free email service
• disposable.txt contains a list of domains that are known to provide disposable email service
• blacklist.txt contains a list of domains that this project will refuse to add to either list

Domains may only be a member of one list.

Updating the database

Run ./update to pull in the latest domains from the sources listed in
sources.txt. All new domains will be placed in free.txt by default.
If any domains provide disposable email service, they may be moved to
disposable.txt.
