Actually, it's terrible and nothing like the Buffer email. This one is impersonal and it's all me, me, me... all about the project and the company, not the customer. And "I think you signed up a couple weeks ago now..." sounds bizarrely vague. I mean, do they know I'm a customer or not? Have they paid any attention to me? Apparently not. And then they expect feedback about their product. This could've been phrased much better so the focus was on improving the customer's experience or resolving their problems.
@neebz: I understand why you didn't like that email, although I wouldn't equate it with the Buffer one
