Cold messages to people in my field, do they work? - 25 weeks in

I want to talk to people in a new field but I hate cold messages. I do not usually post, so bear with me. I worry about bothering people. What did you ask?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

I wrote three short lines: who I am, why them and a small ask for fifteen minutes. About one in four said yes.
