Laravel Transactional Email API & SMTP Transport

Drop-In Symfony & Laravel Mail Support

Because Laravel uses Symfony Mailer under the hood, SendPorter functions as an immediate drop-in replacement for Mailgun, Postmark, and SendGrid without requiring any Composer vendor packages.

    public function envelope(): Envelope
    {
        return new Envelope(
            subject: "Order Confirmation #{$this->order->id}",
            tags: ['order-confirmation', "tier-{$this->order->tier}"],
            metadata: ['order_id' => (string) $this->order->id],
        );
    }

    public function content(): Content
    {
        return new Content(
            markdown: 'emails.orders.confirmation',
        );
    }
}

use App\Mail\OrderConfirmation;
use Illuminate\Support\Facades\Mail;

// Dispatch asynchronously to Redis/database queue
Mail::to($user->email)->queue(new OrderConfirmation($order));

Customizing Headers & Parcel Metadata

SendPorter parses standard custom email headers to enrich your parcel receipts in the dashboard. You can attach campaign categories, tenant IDs, and customer references directly in Laravel:

• X-SendPorter-Tag: onboarding — Groups messages in the analytics reporting dashboard.
• X-SendPorter-Metadata-Tenant: 1049 — Associates messages with specific tenant accounts for billing.
• X-SendPorter-Track-Clicks: true — Enables granular link engagement tracking with zero DNS delay.
