It sounds like you don't like that the email is part of the company's marketing. But wouldn't it be crazy if they sent such an email without making it part of their marketing?

Also, there is differentiation, and explanation of why that's valuable. "We're designed to help improve your'e company's performance in the critical area of XYZ. The ROI on doing that is enormous."

Yes, any competitor could have sent such an email outlining their USP / positioning. But most of them won't, and that's what makes this an excellent example.
