   "email":"ashizhamal@gmail.com",
   "message":"How are you yankee\r\n",
   "created_at":"2017-05-24 03:16:53",
   "updated_at":"2017-05-24 03:16:53"
}

When you are not using [] the you need to parse it with $.parseJSON like below.

jQuery.parseJSON({  
   "id":1,
   "name":"Ashiz",
   "email":"ashizhamal@gmail.com",
   "message":"How are you yankee\r\n",
   "created_at":"2017-05-24 03:16:53",
   "updated_at":"2017-05-24 03:16:53"
});
