README

A lightweight, database-driven newsletter system for Laravel. It handles subscriptions, unsubscriptions via secure signed URLs, and sends RFC-compliant emails to ensure high deliverability (Gmail/Outlook friendly).

Features

• 📦 Database Storage: Saves subscribers to a local newsletter_subscribers table.
• 🔒 Signed Unsubscribe Links: Prevents users from unsubscribing others by protecting the route with a cryptographic signature.
• 📧 RFC Compliance: Automatically adds List-Unsubscribe headers to email responses.
• 🎨 Ready-to-use Views: Includes a standard email layout and unsubscribe success page.
• ⚡ Laravel 10, 11 & 12 Support.

Installation

Installing via Composer

    composer require kadirgulec/newsletter

Post-Installation

After installing, run the migrations to create the subscribers table:

    php artisan migrate

Usage

1. The Subscription Form

You can place this HTML form anywhere in your application (footer, sidebar, popup, etc.).

    <!-- Display Success/Error Messages -->
    @if(session('success'))
        <div class="alert alert-success">{{ session('success') }}</div>
    @endif

    @error('email')
        <div class="text-danger">{{ $message }}</div>
    @enderror

    <!-- Subscription Form -->
    <form action="{{ route('newsletter.subscribe') }}" method="POST">
        @csrf
        <input type="email" name="email" placeholder="Enter your email address" required>
        <button type="submit">Subscribe</button>
    </form>

2. Sending a Newsletter

You can send a newsletter from any Controller, Artisan Command, or Job.

    use Illuminate\Support\Facades\Mail;
    use KadirGulec\Newsletter\Models\Subscriber;
    use KadirGulec\Newsletter\Mail\NewsletterMail;

    // 1. Fetch only active subscribers
    $subscribers = Subscriber::active()->get();

    // 2. Iterate and send
    foreach ($subscribers as $subscriber) {
        Mail::to($subscriber->email)->send(
            new NewsletterMail(
                $subscriber,                                // 1. Subscriber Model
                "Weekly Digest: New Updates",               // 2. Email Subject
                "<h1>Hello!</h1><p>Here is the news...</p>" // 3. Email Content (HTML)
            )
        );
    }
    

Tip: For large lists, it is highly recommended to queue these emails using Laravel Jobs to prevent your page from timing out.

3. Unsubscribing

This process is automated.

1. Every email sent via NewsletterMail includes a Footer Link and a Hidden Header (List-Unsubscribe).
2. The link points to a Signed Route (/newsletter/unsubscribe/{id}?signature=...).
3. If the user clicks it, their status in the database is updated to is_subscribed = false and they are shown a success message.

Database Structure

The package creates a table named newsletter_subscribers.

Customization

Publishing Views

You can publish the email layout and the "Unsubscribe Success" page to your main resources/views folder to customize them.

    php artisan vendor:publish --tag=newsletter-views

This will generate:

1. resources/views/vendor/newsletter/email/standard.blade.php (The Email Layout)
2. resources/views/vendor/newsletter/unsubscribe-success.blade.php (The "You have unsubscribed" page)

Extending the Model

If you need to add relationships (e.g., linking a subscriber to a User), you can extend the model or use the provided one:

    use KadirGulec\Newsletter\Models\Subscriber;

    // Check if a specific email is subscribed
    $isSubscribed = Subscriber::where('email', 'john@doe.com')->first()?->is_subscribed;

Troubleshooting

Error: Route [newsletter.subscribe] not defined.

• Ensure the service provider is loaded. Run php artisan route:list | grep newsletter to check if routes are registered.
• Try running php artisan optimize:clear.

Error: 403 Invalid Signature on Unsubscribe.

• This happens if the URL is modified. Ensure your APP_URL in .env is set correctly (e.g., http://localhost:8000 or https://yourdomain.com). Signed routes use the APP_URL to generate the signature.
