title: Sending mails with no data on Laravel
body: <p>I got this: </p>
  
  <pre><code>Mail::send('emails.orders.attach', null, function($message) use($mail, $subject) {
          $message-&gt;from(Config::get('mail.from["address"]'), Config::get('mail.from["name"]'))
              -&gt;to($mail, 'Sender name here')
              -&gt;subject($subject);
      });
  </code></pre>
  
  <p>And laravel is telling me:</p>
  
  <pre><code> Argument 2 passed to Illuminate\Mail\Mailer::send() must be of the type array, null given
  </code></pre>
  
  <p>I don't need send data, my email template is not sending data except an attached which has all data for the customer.</p>
