And it's not like "email" is some esoteric thing he's only now come into contact with.
For example, don't say "GMail". This is about email. To misquote Babbage: "I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a conclusion".
This conclusion screams of not being able to understand the logical effect of a known fact. I wouldn't want this person troubleshooting anything, for example.
And I didn't see many comments about the rest of his statements. It's a mess. He seems somewhat angry at GMail's suggestions (this would be on the sender side) because sometimes he doesn't want to say what GMail suggests. Again… confusion of ideas.
Actually, now that I think about it I'm seriously suspecting this was written by a bot. More articles than you'd expect are written by bots, and this is close enough to making sense (on multiple points), but without an actual logical point, that it's a possibility.
