Jobs at small Memphis companies nobody posts about after 18 years as a dental hygienist

A friend who works at a local manufacturer says there are openings not advertised online. They like a brief email with a résumé. What do you write in a cold email?

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

Thanks for writing this out. I went through something close to it 3 months ago, and it settled down once I kept a simple log of every call and form.
