In all fairness, after being involved in the hiring process with a few companies, the mass volume of emails that came through was just amazing. Most of the emails were either guys trying their luck, or just junk emails.
At one company were we receiving over 30 a day. Small operations don't always have the same level of staff that say, 747 operations, have available to them.
A follow up email or even better, a phone call, would have done wonders for the candidate.
Other things to get CV noticed was to have substantial relevant experience in the emails subject title so the CV could be noticed without even opening it.
