This reminds me of when Urban Airship shut down their free transactional push notification service a while back. It turns out theres so much more money in the marketing side than the transactional side (profit center vs cost center), and if you're going to run a marketing company it doesn't make sense to give away a service to people who will never become the type of customer you want. We've been referring clients to mandrill for a long time on many different project and although a few have had enough success to hit the level where they start paying, for the most part it's been just a giveaway. It doesn't make it any less painful for those clients that we now need to switch (especially the few that are using the inbound features - ugh) but I can see where they're coming from in this change.
