I've only recently started networking and I've had a pretty good hit rate with cold e-mails. I'm always super humble and diplomatic with my emails afraid to have someone fulminate me for asking to have a chat over the phone or emailing questions. Always putting the Dear XXXX, and the whole formal letter shebang.
I always explain my connection and how I have their contact, but the connection could be like a friend of a friend of a friend. I don't have strong connections to this particular industry I'm interested in so I'm cold networking. I was wondering if professionals get pissed off when you cold e-mail asking for advice? Or is it flattering/not a big deal to them.
