Me too, have no problem using pushbullet TEXT messages. There is a misunderstanding regard to Amazon: The problem arises when you want to insert an IMAGE inside these text messages. This is a feature of pushbullet as described in their API. So, I'm not interested in using Amazon server: it's Pushbullet that uses Amazon server to store the image and then attach it in their text message! They describe their procedure API here: https://docs.pushbullet.com/v9/#pushes
