Disposable Email Checker is a library that allows applications to check for users signup with disposable email addresses. This is very important for services that provide some trial period based on the email address. Hence, if users use disposable addresses, then they can potentially bypass the time limit. Other applications may use it to make sure that they have valid emails that they can use for future correspondence.
The library currently contains > 1,900 domains and growing.
This project started with offering a php library, but in v2, it has been refactored to separate the domain lists from the code. This enables the following scenarios:
- Providing implementations in multiple languages that consumes such data files.
- Enable apps to easily embed these data files and consume them directly.
- Simplify the process of updating the list to add more domains.
This library has a list of rules that are used to determine whether an address is disposable or not. The library does not connect to the Internet to determine the kind or the validity of the address. The library may be enhanced in the future to provide applications with ways of explicitly requiring online checks.
This library is available as open source with MIT license, so you can use it in both open source and commercial applications. The best ways to contribute back to this library are:
- Report service providers that the library should detect but it doesn't. See section below for validating disposeable domains.
- Report bugs and feature request in the bug tracker.
- Provide ports for the library in languages other than PHP.
To report bugs and feature requests use the associated github bug tracker.
Before submitting a PR with new disposable email domains, please validate that such domain are really disposable via the Kickbox service.
In the following URL replace {domain} with your domain (e.g. example.com) and make sure
it returns disposable: true.
https://open.kickbox.com/v1/disposable/{domain}
Here is how to run the unit tests:
composer install
vendor/phpunit/phpunit/phpunit php/tests/disposable_email_checker_tests.php
The versioning for this library is formatted as follows "1.2.3".
(1) This is the major version which will change when there are major changes or re-implementation.
(2) This is the minor version which will change when the APIs changes. Most of the time these won't be breaking changes, but sometimes they may be.
(3) This is the data version which is the only one changed in releases that just update the rules that are used to determine that an email address is disposable.
