Laravel - Mail - Pushing To Specific Queues

Since all mailable classes generated using the make:mail command make use of the Illuminate\Bus\Queueable trait, you may call the onQueue and onConnection methods on any mailable class instance, allowing you to specify the connection and queue name for the message:

    
    $message = (new OrderShipped($order))
                    ->onConnection('sqs')
                    ->onQueue('emails');
    
    Mail::to($request->user())
        ->cc($moreUsers)
        ->bcc($evenMoreUsers)
        ->queue($message);
