As a non-user of Mandrill or MailChimp I look on this whole episode as a classic example of how not to make product changes. I suspect YC17 will be studying this as how not to go.<p>One thing I don&#x27;t understand if this is all about the Benjamins while not just increase the price and leave the functionality unchanged. This way you would only lose the customers who are price sensitive and not those that now have to change their back ends.
