Laravel API Mail

A modern, extensible multi-provider HTTP Email API driver and notification package for Laravel 10, 11, 12, and 13.

Designed to replace legacy SMTP with provider-native HTTP APIs, featuring out-of-the-box integration with the Hostinger Mail API (with automated mailbox resourceId lookup), fluent method-chained message composition, inline Markdown rendering, and a clean grayscale HTML email theme.

Features

• ⚡ Hostinger Mail API Integration: Automatic fetching and caching of mailbox resourceId from Hostinger's GET /api/v1/me endpoint matched by sender (from) email address.
• 🔀 Multi-Provider Architecture: Pluggable driver manager (EmailProviderManager) allowing developers to easily switch providers via config or specify distinct providers per notification message.
• 🎨 Fluent Message Builder (ApiMailMessage): Chainable syntax inspired by Laravel's SimpleMessage (->subject(), ->greeting(), ->line(), ->action(), ->from(), ->to(), ->provider()).
• 📝 Inline Markdown Support: Automatically compiles Markdown inline formatting (**bold**, *italic*, links) inside notification lines into clean HTML.
• 🖼️ Custom Blade & Markdown Views: Pass custom templates using ->view('emails.custom', $data) or ->markdown('emails.custom', $data) when needed.
• 🖤 Grayscale HTML Theme: Included out-of-the-box with a clean, minimal black-and-white responsive HTML template matching standard Laravel notification aesthetics.
• 🔔 Notification Channel & Mailer Transport: Works via dedicated ApiMailChannel (toApiMail()) or as a registered Symfony Mailer transport driver (hostinger).

Requirements

• PHP: ^8.2 | ^8.3 | ^8.4
• Laravel: ^10.0 | ^11.0 | ^12.0 | ^13.0

Usage Guide

1. Sending via Laravel Notifications

Use ApiMailChannel and return an ApiMailMessage in your notification's toApiMail() method:

namespace App\Notifications;

use AnjanTalukdar\ApiMail\Channels\ApiMailChannel;
use AnjanTalukdar\ApiMail\Messages\ApiMailMessage;
use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;

class AccessRequestStatusNotification extends Notification
{
    use Queueable;

    public function __construct(public $accessRequest) {}

    public function via(object $notifiable): array
    {
        return ['database', ApiMailChannel::class];
    }

    public function toApiMail(object $notifiable): ApiMailMessage
    {
        $statusText = ucfirst($this->accessRequest->status);
        $isApproved = $this->accessRequest->status === 'approved';

        return (new ApiMailMessage)
            ->provider('hostinger') // Optional: defaults to config('api-mail.default')
            ->from('info@yourdomain.com', 'Your App')
            ->to($notifiable->email)
            ->subject('Your Request to Join ' . $this->accessRequest->space->name . ' was ' . $statusText)
            ->greeting('Hello ' . ($notifiable->name ?? 'User') . ',')
            ->line("Your request to join the **{$this->accessRequest->space->name}** space has been **{$this->accessRequest->status}**.")
            ->action('Go to Dashboard', url('/app'))
            ->level($isApproved ? 'success' : 'error');
    }
}

2. Direct Dispatching via Facade

Send emails dynamically using the ApiMail facade:

use AnjanTalukdar\ApiMail\Facades\ApiMail;
use AnjanTalukdar\ApiMail\Messages\ApiMailMessage;

$message = (new ApiMailMessage)
    ->from('info@yourdomain.com', 'Support Team')
    ->to('user@example.com')
    ->subject('Welcome to Our Platform')
    ->greeting('Hello John!')
    ->line('Thank you for joining our platform.')
    ->action('Get Started', 'https://yourdomain.com/app');

ApiMail::send($message);

3. Dynamic Multi-Provider Routing

You can route different notifications or messages to distinct email providers:

// Send transactional email via Hostinger
$transactionalMsg = (new ApiMailMessage)
    ->provider('hostinger')
    ->to('user@example.com')
    ->subject('Invoice #1004');

// Send marketing broadcast via Resend (or other driver)
$marketingMsg = (new ApiMailMessage)
    ->provider('resend')
    ->to('user@example.com')
    ->subject('New Features Released!');

4. Custom Blade Views

Render custom Blade templates instead of the built-in HTML theme when required:

return (new ApiMailMessage)
    ->to($notifiable->email)
    ->subject('Custom Card Notification')
    ->view('emails.custom-welcome', [
        'user' => $notifiable,
    ]);

Hostinger Mailbox Auto-Resolution Architecture

Hostinger's Mail API requires sending emails via a specific mailbox resourceId endpoint: POST /api/v1/mailboxes/{resourceId}/send

This package automates resource ID lookup seamlessly:

1. HostingerMailboxResolver issues a GET /api/v1/me request to retrieve account mailboxes.
2. It maps mailbox email addresses (e.g., info@yourdomain.com $\to$ ACd58567a68c96e2b8c6624e02cbbd).
3. Results are cached locally (default: 1 hour) so subsequent email sends incur zero extra API overhead.
4. If a sender address is newly created, it automatically invalidates cache and retries lookup seamlessly.

Extending with Custom Drivers

Register custom API email drivers at runtime via the facade:

use AnjanTalukdar\ApiMail\Facades\ApiMail;

ApiMail::extend('custom_driver', function ($app, $config) {
    return new CustomEmailProvider($config);
});

Testing

Run tests using PHPUnit / Pest:

composer test

Or within a host Laravel application:

php artisan test --filter=ApiMailPackageTest
