Core Email Copywriting Rules

1. Subject line = 80% of the result — if it doesn't get opened, nothing else matters
2. One email = one goal — don't ask for multiple things in one email
3. Write like a human, not a brand — "Hey John" beats "Dear Valued Customer"
4. Short wins — under 150 words gets more replies than 500 words
5. Specific beats vague — "saved 3 hours/week" beats "saves time"
6. Plain text converts better for cold/personal emails — no fancy HTML
7. One CTA only — one link, one ask, one action
8. The PS line gets read — always use it for your most important point
