I'm a little confused about what to do with these recruiters that send emails to me out of the blue. If I respond to them and politely mention that I'm happily employed and have no intention of leaving, they continue to send email. (eg. do you have any friends? the company is pre ipo. keep me in the loop. etc. etc. on and on.) But it feels rude to not respond to someone that sends me a personal email. So I've started sending emails that say: "I am happily employed with no intention of leaving. I have no friends. Money does not motivate me. I'll keep you in the loop. -pb"
