So you are defending them (at least in the first sentence)from your speculation based on what you heard around town, that customers were simply not sustainable fits... Wouldn't it make sense they not offer a service package that is unsustainable in the first place? The clients myself and many others put on Mandrill were certainly not free tier anything, and they still offer the service, just under he Mailchimp name. (point being it can't be too unsustainable if they still offer it)

Customers I know who were ultimately stuck by being heavily integrated in the Mandrill API still suffered issues and downtime with the flawed account migration process. Just about every paying (and non paying) Mandrill customer got screwed in one way or another.
