如何将View :: make转换为电子邮件

In my controller I return this view which I am trying to convert to an email shown below. The view works fine but my email is not sending. I'm not sure why.

 public function emailRegistrationConfirmation()
 {

    $user = Auth::user();
    $errors = Session::get('error');
    $warning = Session::get('warning');
    $info = Session::get('info');
    $success = Session::get('success');

    $return_mail = Config::get('mail.from.address');

    $attendeesIds = $user->attendees()->get()->lists('id');

    $programs = ScheduledProgram::whereHas('registeredAttendees', function($q) use ($attendeesIds){
                $q->whereIn('attendees.id', $attendeesIds);
              })->where('registration_start_date', '<=', $today)
                ->where('end_date',                '>=',  $today)
                ->get();


    $sent =  Mail::send('user/registration/show', compact( 'user','programs', 'programsProcessing', 'cart','errors', 'successes', 'info', 'warning'), function($message) use ($return_mail, $user)
    {

      $message->to($return_mail, 'Confirmations')
              ->subject('RECEIPT: ' . $user->first_name . ' ' . $user->last_name);
    });

    return $sent?'sent':'not sent';

    /*OLD return View worked fine*/
    return View::make('user/registration/show', compact('user','programs', 'programsProcessing', 'cart'))
          ->withError($errors)
          ->withSuccess($success)
          ->withInfo($info)
          ->withWarning($warning);
    }

My page returns not sent. I guess this means the Mail::send failed. PhpDebugBar shows in the email tab

Message-ID: <f6d6143403eda66af66ada902039c149@dev.registration.innisfillibrary.ca>

Send HTML email like this in Laravel and emails.register means path will be emails/register.blade.php

Mail::send(['html' => 'emails.register'], [
      'url' => url("set-password/some-verify-token"),
      'email' => $request->input('email')
   ], function ($mail) use($email) {
      $mail->from(env('SUPPORT_EMAIL'), env('APP_NAME'));
      $mail->to($email);
      $mail->subject('welcome');
});

Return file path is wrong so change it user/registration/show to user.registration.show and file path will be user/registration/show.blade.php

return View::make('user.registration.show', compact('user','programs', 'programsProcessing', 'cart'))
          ->withError($errors)
          ->withSuccess($success)
          ->withInfo($info)
          ->withWarning($warning);
    }
