#Installation

Install the package via Composer:

composer require erag/laravel-disposable-email

#Laravel 11 and 12

Manually register the service provider in /bootstrap/providers.php:

return [
    // Other providers...
    EragLaravelDisposableEmail\LaravelDisposableEmailServiceProvider::class,
];

#Laravel 8, 9, and 10

No configuration needed — the package uses Laravel’s auto-discovery.

#Publish Configuration

php artisan erag:install-disposable-email

This creates a config/disposable-email.php file where you can customize the blacklist path, auto-sync settings, and remote source URLs.

#Features and Usage

#1. Form Validation

Block disposable emails directly in your form validation.

Option 1: String-based rule

public function rules()
{
    return [
        'email' => ['required', 'email', 'disposable_email'],
    ];
}

Option 2: Class-based rule

use EragLaravelDisposableEmail\Rules\DisposableEmailRule;
 
public function rules()
{
    return [
        'email' => ['required', 'email', new DisposableEmailRule],
    ];
}

If someone submits an email like user@temp-mail.org, validation will fail with an error like: "Please use a real email address."

#2. Runtime Email Checking

Use the DisposableEmail facade anywhere in your application:

use EragLaravelDisposableEmail\Facades\DisposableEmail;
 
$email = 'user@mailinator.com';
 
if (DisposableEmail::isDisposable($email)) {
    return redirect()->back()->with('error', 'Disposable emails are not allowed.');
}

This is useful for checking emails after registration or during user updates.

#3. Blade Directive

Display different UI content based on whether an email is disposable:

@disposableEmail($user->email)
    <p class="text-red-500">This email is disposable.</p>
@else
    <p class="text-green-500">This email is valid.</p>
@enddisposableEmail

Great for admin dashboards or user profile pages.

#4. Auto-Sync Disposable Domains

Keep your domain list up-to-date using the sync command:

php artisan erag:sync-disposable-email-list

Automate it with Laravel Scheduler in app/Console/Kernel.php:

protected function schedule(Schedule $schedule)
{
    $schedule->command('erag:sync-disposable-email-list')->weekly();
}

By default, it syncs from trusted sources like disposable-email-domains and fakefilter. You can add more URLs in the config file.

#5. Custom Blacklist

Need to block additional domains? Add them to the blacklist file:

storage/app/blacklist_file/disposable_domains.txt

One domain per line:

fakeemail.com
spamdomain.org

The package will merge these with its internal list during validation.

#6. Zero Configuration Required

Don’t want to change any settings? No problem.

Just install the package, and it works out of the box. Customization is fully optional.

#Why Block Disposable Emails?

• Cleaner Database: Store only real users, improving data integrity.
• Less Spam: Prevent fake or abusive accounts.
• Improved Deliverability: Avoid sending to addresses that bounce.
• Enhanced Security: Stop malicious actors from abusing sign-ups or free trials.

For example, in a SaaS app offering a free trial, users could abuse the trial repeatedly using disposable emails. Or on a forum, spam bots could create hundreds of fake accounts. This package shuts that down — fast.

#Conclusion

The laravel-disposable-email package is a simple yet powerful way to block disposable emails in your Laravel app. With features like:

• Validation rules
• Runtime checks
• Blade directives
• Auto-syncing
• Custom blacklists

it gives you everything you need to protect your application from spam and fake sign-ups.

It's open-source, actively maintained, and highly recommended for any Laravel developer serious about maintaining a secure and clean user base.

Give it a try — and keep your database junk-free.
