Performance issue in sending email in Laravel 5.1

I am using below code to send email in Laravel 5.1

Mail::send('Project.Emails.Award', $data, function($message) 
{
    $message
            ->to('EmailAddress', 'EmailAddress')
            ->subject('hi');
});

Here the problem is the above function takes min 5 seconds to complete the processing.

Question : Is there deliver async method s that I don't need to wait for the response ?
