        if($validationarray->fails())

            foreach ($validationarray ->messages()->getMessages() as $field_name =>$message):
                $response['message']=$message;
                $response['message1']=$request->email;
            endforeach;
            $response['status']="failed";
            return response()->json($response);
        }
        // start pass data to model
        $data=array(
            'email'     =>$request->email,

        // start add data
        $add=Subscribe::create($data)->id;
        if(false !=$add)
        {
            return response(['status'=>'success',"message"=>"Your Email Added Successfully"]);

        }else{
            return response(['status'=>'failed',"message"=>"Error Adding data please try again !!"]);

        }

    }

}
