Word-of-mouth leads in Fresno

Two small Fresno employers told me they are hiring but have not posted yet. 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.

A short email with two sentences about what you can do and your résumé attached worked for me. I followed up after a week.
