sending one composed text to emails saved in database using laravel

I have created a form, upon its submission it goes to email id which is stored in Laravels mail function. But I want to send same email to multiple people whose email-id are stored in database. Here is my code:

Routes:

Route::get('contactform', 'ClientsController@display1');
Route::post('contactform', 'ClientsController@contact');

My controller:

public function display(){
    $data = Input::get('agree');
    $count = count ($data);
    if($count){
        return $this->contact( $data,$count);
    }
    else{
        echo "Select At least one email-id.";
        return view('clientinfo.backtoprev');
    }

}

    public function display1(){

        return view('contactform');
    }

    public function contact($data,$count){
        $input = Input::only('name', 'email', 'msg');

        $validator = Validator::make($input,
            array(
                'name' => 'required',
                'email' => 'required|email',
                'msg' => 'required',
            )
        );

        if ($validator->fails())
        {
            return Redirect::to('contact')->with('errors', $validator->messages());
        } else { 


            Mail::send('contactemail', $input, function($message) use($data)
            {
                $message->from('your@email.address', 'Your Name');

                $message->to( $data);
            });

            return view('clientinfo.display', compact('data','count'));
        }

    }

here is my view "Contactform"

{!! Form::open(array('action' => 'ClientsController@contact','method' => 'post','name'=>'f1' , 'id'=>'form_id'))!!}  
    @if(Session::has('errors'))
        <div class="alert alert-warning">
            @foreach(Session::get('errors')->all() as $error_message)
                <p>{{ $error_message }}</p>
            @endforeach
        </div>
    @endif
       //My fields, name & message
{!! Form::close() !!}

From the "display" method i'm passing two variables $data and $count to contact method, but after filling form and hitting submit error comes as

Missing argument 1 for App\Http\Controllers\ClientsController::contact()
