Thanks. Very useful to know. As I mentioned, I never used SES. I'm sure SES provides great building blocks for something similar to Mandrill. But the value-add of ESP is tying those things together, so one can easily, e.g. search for an email address and find all previous emails sent, the delivery status etc, not to mention a nice web interface... Open/Click tracking is also quite useful in some cases, and probably isn't supported by SES either(?)
