I work for JangoSMTP, a transactional email service provider. Amazon SES certainly has the lowest price out there, but as you mentioned, there are a lot of reasons to choose a service provider for transactional emails, and only one is price. If you are looking for a minimalist service for the lowest price, then the Amazon SES may make sense for you. JangoSMTP is more robust, in that it has both API and SMTP relay options, along with bounce and unsubscribe management, open and click tracking and advanced reporting (Google Analytics, logging, etc.).
From what we have learned, Amazon SES does little more than send out emails. If you have the resources to implement your own list management, campaign management, DKIM signing, reporting, etc., then it's a great choice. If you need a company to do this for you though, you'll still want to go with a service like JangoSMTP.
