It is poor taste to point out someone's bad grammar or weaker English skills, not to mention unproductive to a conversation.
I'm certain others understood what Tom meant by "above email", just as I did. People often have a hiccup in their minds thinking "phone call" or "voice mail" and then typing email, or as in this case I think Tom may have meant "post." Either way, we got the gist.
People are chiming in their frustration with this and don't have to ask a question as a reply. Give the guy a break and practice kindness.
