Did you get my email?
How would I know if I got your email? How would I know if I got the specific email to which you refer? What if you sent me two emails -- let's say the first was "I love you" and the second was "but I stole your wallet and your ATM card and your dog and I'm sleeping with your brother. Is that OK with you?" -- and I only saw only the first one? You'd ask "Did you get my email?" and I'd say, "Yes," and we'd both be screwed (pun intended.)
Don't ask me if I got your email. Ask me if I got your amail about (whatever the hell it was about.)
OK, I feel better now.
