Earlier quoted context omitted.
Automated emails are pretty shit, and easy to spot. They also tend to turn off most people, making recruiting more difficult.
Yep. Any time I see a recruiter try to automate initial contact using a tool like Jobdiva or some such, it's an instant disqualification. Most of the time it's just plain shotgunned out and I never hear anything beyond the initial email. I had one recruiter, after doing that, call me and inquire -- I told him no, and explained to him that I don't do business with those who willingly use spamming tools.
Knowing that of 20 people the recruiter knows that are a good fit, only 2 might be available, what would your preferred method be of them going about their job?
