This brings about another important point in making an application: Email vs Snailmail.

Different HR Managers have difference preferences. Some like the ability to "flick" through a hard copy, others like the convenience of email. (ie they don't clutter the desk, and take 10% as much time to respond to, especially the declined ones). I used to share an office with the HR Manager, and she spent god knows how long copying, stamping and returning applications by post.
