How do I write a cold email that people actually reply to?

A starting point

Keep it short, personal, and about them, not you. Nail a subject line that sparks curiosity, open with a specific reason you're reaching out to *this* person, state the value in one or two lines, and end with a single, low-friction call to action. If your email takes more than 15 seconds to read, it's too long.
