Disposable / Temporary Email Address Filter

This package provides a method for determining whether an email address is a disposable / temporary email address.

All credit to the maintaining of the list of disposable / temporary email addresses goes to github.com/disposable-email-domains/disposable-email-domains.

This project and it's maintainer(s) do not discourage the use of such disposable / temporary email addresses, but simply allows for the detection of such.

Installation

PHP 8.2 or above is required. If PHP 8.1 is required please use version 4. If PHP 7.4 to 8.0 is required please use version 3.

To install via Composer:

composer require elliotjreed/disposable-emails-filter

Usage

Check if the email address is in the temporary domain list

The checker / filter can either be used via a static or non-static means:

<?php

require 'vendor/autoload.php';

use ElliotJReed\DisposableEmail\Email;

if ((new Email())->isDisposable('[email protected]')) {
    echo 'This is a disposable / temporary email address';
}

or

<?php

require 'vendor/autoload.php';

use ElliotJReed\DisposableEmail\DisposableEmail;

if (DisposableEmail::isDisposable('[email protected]')) {
    echo 'This is a disposable / temporary email address';
}

List all domains in the temporary email domain list

The lister can either be used via a static or non-static means:

<?php

require 'vendor/autoload.php';

use ElliotJReed\DisposableEmail\Email;

foreach ((new Email())->getDomainList() as $domain) {
    echo $domain . PHP_EOL;
}

or

<?php

require 'vendor/autoload.php';

use ElliotJReed\DisposableEmail\DisposableEmail;

foreach (DisposableEmail::getDomainList() as $domain) {
    echo $domain . PHP_EOL;
}

If an invalid email address is provided then an InvalidEmailException is thrown, so it is advisable to check that the email address is valid first. For example:

<?php

require 'vendor/autoload.php';

use ElliotJReed\DisposableEmail\Email;

$email = 'not-a-real-email-address#example.net';

if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
    if ((new Email())->isDisposable($email)) {
        echo 'This is a disposable / temporary email address';
    }
} else {
    echo 'This is not a valid email address';
}

Would output:

This is not a valid email address

You can also provide your own custom domain list in a new line separated plain-text file, for example:

example.com
example.net

Then passing the file location into the constructor:

<?php

require 'vendor/autoload.php';

use ElliotJReed\DisposableEmail\Email;

new Email('/path/to/custom/list.txt');

If an invalid list is provided then an InvalidDomainListException is thrown.
