Laravel-5 SMTP mail

There isnt any error but dont send email this code. Why ?

public function sendEmailReminder() {

    `enter code here`Mail::send([],[],function($message){
    $message->from('destek@crm.gen.tr', 'Your Application');

    $message->to('birgul@laysos.com.tr')->subject('Your Reminder!');
   });

    return back()->with('success','email gönderildi');
}
