Word-of-mouth leads in Portland - 3 weeks in

I asked around at a community meeting and got three leads. It has been weighing on me all week. They like a brief email with a résumé. What do you write in a cold email?

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

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