🗑 Disposable email detection

PHP package that detects disposable (temporary/throwaway/fake) email addresses. It is framework-agnostic and has no dependencies, but includes support for Laravel. It validates email addresses to ensure they are genuine, which is useful for managing account sign-ups and assessing the number of legitimate email addresses in your system.
This tool also helps to avoid communication errors and blocks spam addresses.

🚀 The lookup is superfast O(1) because disposable email domains are stored locally using a native PHP hash set..

🚡 The list of disposable email domains is regularly updated automatically from trusted external sources.

📦 Installation and Usage examples

Note

Read below for Laravel specific instructions.

Require this package with composer using the following command:

composer require beeyev/disposable-email-filter-php

Basic usage

Simple check if the email address is disposable:

<?php
require __DIR__ . '/vendor/autoload.php';

use Beeyev\DisposableEmailFilter\DisposableEmailFilter;

$disposableEmailFilter = new DisposableEmailFilter();

// Check if email address is disposable
$disposableEmailFilter->isDisposableEmailAddress('ostap@gmail.com');     // false
$disposableEmailFilter->isDisposableEmailAddress('john@tempmailer.com'); // true

Adding custom disposable(blacklisted) and whitelisted domains:

Note: Whitelisted domains have higher priority than blacklisted domains.

<?php
require __DIR__ . '/vendor/autoload.php';

use Beeyev\DisposableEmailFilter\DisposableEmailFilter;

$disposableEmailFilter = new DisposableEmailFilter();

// Add multiple custom domains to blacklist
$disposableEmailFilter->blacklistedDomains()->addMultiple(['mailinator.com', '10minute-mail.org']);

// Add one domain to whitelist
$disposableEmailFilter->whitelistedDomains()->add('tempmailer.com');

$disposableEmailFilter->isDisposableEmailAddress('john@tempmailer.com');    // false (because it's whitelisted now)
$disposableEmailFilter->isDisposableEmailAddress('john@mailinator.com');    // true
$disposableEmailFilter->isDisposableEmailAddress('john@10minute-mail.org'); // true
$disposableEmailFilter->isDisposableEmailAddress('john@gmail.com');         // false

It is also possible to add blacklisted and whitelisted domains using constructor dependency:

use Beeyev\DisposableEmailFilter\CustomEmailDomainFilter\CustomEmailDomainFilter;
use Beeyev\DisposableEmailFilter\DisposableEmailFilter;

$blacklistedDomains = new CustomEmailDomainFilter(['blacklisted1.com', 'blacklisted2.com', 'blacklisted3.com']);
$whitelistedDomains = new CustomEmailDomainFilter(['abc2.com', 'whitelisted1.com']);
$disposableEmailFilter = new DisposableEmailFilter($blacklistedDomains, $whitelistedDomains);

$disposableEmailFilter->isDisposableEmailAddress('test@whitelisted1.com'); // false - whitelisted

Note: You can develop your own filtration logic by creating a custom class that implements the CustomEmailDomainFilterInterface

Handling exceptions:

If you try to pass empty string or string with invalid email format, an exception will be thrown.

use Beeyev\DisposableEmailFilter\DisposableEmailFilter;
use Beeyev\DisposableEmailFilter\Exceptions\InvalidEmailAddressException;

$disposableEmailFilter = new DisposableEmailFilter();

try {
    $disposableEmailFilter->isDisposableEmailAddress('john:gmail.com'); // Exception will be thrown because of invalid email format
} catch (InvalidEmailAddressException $e) {
    echo $e->getMessage();
}

If you expect that email address might be invalid and don't want to wrap the code into try/catch,
you can use isDisposableEmailAddressSafe method to check if email address is correctly formatted before checking if it's disposable:

$disposableEmailFilter = new DisposableEmailFilter();

$emailAddress = 'john:gmail.com';

if ($disposableEmailFilter->isEmailAddressValid($emailAddress)) {
    $disposableEmailFilter->isDisposableEmailAddress($emailAddress);
}

Laravel specific usage

This package includes a service provider and form validation rule for Laravel.

Install the package (Laravel)

composer require beeyev/disposable-email-filter-php

The package will be automatically registered using Laravel auto-discovery mechanism.
But if you need to do it manually, you can add the following line to the providers array in the config/app.php file:

Beeyev\DisposableEmailFilter\Adapters\Laravel\DisposableEmailFilterServiceProvider::class,

Form validation (Laravel)

Use validation rule not_disposable_email or object new NotDisposableEmail(), to check that specific field does not contain a disposable email address.

Note

❗ Place it after the email validator to ensure that only valid emails are processed.

Example:

// Using validation rule name:
'email_field' => 'required|email|not_disposable_email',

// Or using a validation rule object:
'email_field' => ['email', new NotDisposableEmail()],

Using facades (Laravel)

You can use the DisposableEmail facade to access the DisposableEmailFilter instance:

use Beeyev\DisposableEmailFilter\Adapters\Laravel\Facades\DisposableEmail;

DisposableEmail::isEmailAddressValid('foo@fakemail.com');

Config file and translations (Laravel)

Optionally, you can publish the config file and translations to customize the package behavior:

php artisan vendor:publish --tag=disposable-email-filter

This command will create a disposable-email-filter.php config file in the config directory and translation files in the lang/vendor/disposable-email-filter directory.

Updating

Since the list of disposable email domains is regularly updated, it is important to keep the package up to date.
A new PATCH version of the package is released whenever the list is updated.
These updates are safe and non-breaking, allowing you to update the package via this composer command:

composer update beeyev/disposable-email-filter-php

You can run this command every time in CI/CD pipelines before the project is deployed.
