It's also good to keep in mind when email is your first contact, it should be warm, friendly, but honest, clear and direct. Typos or unclear logical flow really detract from an email first impression. For me personally it's the difference between deleting a message halfway through, and reading it to finish. I think it's interesting that personal email addresses got a better response. That's something I will have to look into to. Basically, I think people are adapting to all of the calls that they normally receive, and getting something new in an inbox is relatively safer.
