If he'd posted the email headers and they turned out to be legit I might have gotten excited.
However, the 'compilation of ideas' is merely a row of icons. Plus the text "Tell me what you think and I'll send you a followup in a few minutes" sounds like something someone pretending to sound official might write. And it doesn't even make sense. Did the sender expect to receive feedback so fast that he was confident he'd send a followup within just a few minutes? So fake. Although it's interesting no blue has responded yet.
