I just started playing with it to get my exim server to send my outgoing mail through. It seemed like AWS had a bit of trouble understanding that I was only looking for something low volume and transactional. They kept wanting to know how I handled unsubscribe requests. But I finally got them to ok the account (with a 40,000 email/month email limit, after I told them 100/month would be fine). After I sent a few test emails and looked at their spam scores, they were ok enough to probably get through most of the time but not great. I then tried SendGrid and they were both much easier to set up and the test messages got much better spam scores.
