The other way to think of emails is as datagrams. Sometimes you'll get a reply, sometimes you won't. Or, from the other side: sometimes you'll be able to answer, sometime you won't. Don't feel bad about the latter case. If you don't hear back after a while and you really really need an answer, simply resend. People go through email bankruptcies a few times a year. It's safer to assume it is an unreliable channel.
