The Lettermint Laravel driver integrates seamlessly with Laravel’s native mail system, allowing you to send emails using Laravel’s familiar Mail facade and Mailable classes.

​
Basic email sending

Once you’ve configured the Lettermint transport, you can send emails using Laravel’s standard Mail methods: 
use Illuminate\Support\Facades\Mail;
use App\Mail\WelcomeEmail;

Mail::to('[email protected]')->send(new WelcomeEmail($user));

​
Sending to multiple recipients

You can send emails to multiple recipients using Laravel’s to(), cc(), and bcc() methods: 
use Symfony\Component\Mime\Address;
use Illuminate\Support\Facades\Mail;

Mail::to([
    new Address('[email protected]', 'John Doe'),
    new Address('[email protected]', 'Sales Team')
])
->cc('[email protected]')
->bcc('[email protected]')
->send(new WelcomeEmail());

​
Email content

The driver supports both HTML and plain text email content: 
use Symfony\Component\Mime\Email;

$email = (new Email)
    ->from('[email protected]')
    ->to('[email protected]')
    ->subject('Hello world!')
    ->html('<p>This is the HTML version</p>')
    ->text('This is the plain text version');

​
Using Laravel Mailables

Create a Mailable class to organize your email logic: 
namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;

class WelcomeEmail extends Mailable
{
    use Queueable, SerializesModels;

    public function __construct(
        public User $user
    ) {}

    public function content(): Content
    {
        return new Content(
            view: 'emails.welcome',
        );
    }

    public function envelope(): Envelope
    {
        return new Envelope(
            subject: 'Welcome to our platform!',
        );
    }
}
Then send it: 
Mail::to($user->email)->send(new WelcomeEmail($user));

​
Custom headers

You can add custom headers to your emails: 
$email->getHeaders()->addHeader('X-Custom-Header', 'test-value');
The Lettermint driver automatically handles all standard email headers including From, To, CC, BCC, Subject, Reply-To, and Content-Type.

​
Reply-To addresses

Specify a reply-to address for your emails: 
use Symfony\Component\Mime\Email;

$email = (new Email)
    ->from('[email protected]')
    ->to('[email protected]')
    ->replyTo('[email protected]')
    ->subject('Need help?')
    ->text('Contact us at [email protected]');

​
Queued emails

Send emails asynchronously using Laravel’s queue system: 
use Illuminate\Support\Facades\Mail;

Mail::to($user->email)->queue(new WelcomeEmail($user));
When using queued emails, consider enabling idempotency to prevent duplicate sends if jobs are retried.

​
Error handling

The driver throws a TransportException if the API request fails: 
use Symfony\Component\Mailer\Exception\TransportException;
use Illuminate\Support\Facades\Mail;

try {
    Mail::to($user->email)->send(new WelcomeEmail($user));
} catch (TransportException $e) {
    Log::error('Failed to send email: ' . $e->getMessage());
}

​
Message ID tracking

After sending an email, Lettermint returns a message ID that’s automatically set on the email. This ID can be used to track the email’s delivery status: 
$sentMessage = Mail::to('[email protected]')->send(new WelcomeEmail());
$messageId = $sentMessage->getMessageId();

// Example: [email protected]
The message ID is formatted to comply with RFC 5322 standards. If Lettermint’s ID doesn’t contain an @ symbol, the driver automatically appends @lmta.net.
