Jobs at small Louisville companies nobody posts about - any advice?

I asked around at a community meeting and got three leads. I do not usually post, so bear with me. One is a print shop, one is an accounting firm and one is a clinic. What do you write in a cold email?

Keep a list of who you contacted and when. It makes follow-ups easy.

Small employers often hire on recommendation. Ask neighbours, former co-workers and your library.
