You have to pass along $data to the callback in your send method. Refer the line where Mail façade is used.
public function sendmail(Request $request)
{
$data = [
'subject' => $request->input('subject'),
'name' => $request->input('name'),
'phone' => $request->input('phone'),
'email' => $request->input('email')
];
Mail::send('mail.sendmail' , function($msg) use($data){
$msg->from('mygmail#gmail.com', 'Hung Nguyen');
$msg->to('mygmail#gmail.com', 'Hung Manh')->subject($data['subject']);
});
return redirect()->route('contact.index');
}
