Passing variable data using sessions in Laravel 5.8

class PaymentGatewayController1 extends Controller
{
public function getPaymentGatewayResponse(Request $request)
{
    $input = request()->input();

    Session::put(['email' => $input['email']]);
    Session::save();
return view('elements.blocks.iframe2',  ['response' => $input]);
}
}

Now I need this session value to another controller

class CheckoutController extends Controller
{
public function store(Request $request)
{

    $input = request()->all();
    $data = $request->session()->get('email');
    dd($data);
}
}

it returns null value

Laravel Version 5.8
