Building a Bulk Email Sender with Laravel

Why I built it

At Adventure Dhaka Ltd, we needed a way to send thousands of personalized emails without relying on expensive third-party services. So I built one.

Architecture

The system uses Laravel queues with database driver for job processing. Each email batch is split into chunks of 100, processed by separate workers, with real-time progress tracking via WebSockets.

// Queue job example
class SendEmailBatch implements ShouldQueue
{
    public function handle(): void
    {
        // Process 100 emails
    }
}

Features

• Template engine with Blade variables
• List management with import/export
• Open & click tracking via pixel tracking
• Bounce handling with automatic unsubscribe
• Rate limiting per provider

Results

Processing 50,000+ emails daily with 98% delivery rate. Replaced Mailchimp entirely.
