## Best Practices

1. **Subject Lines**
   - Keep under 60 characters
   - Use curiosity or value proposition
   - Avoid spam triggers (FREE, URGENT, etc.)

2. **Content**
   - Lead with value, not asks
   - One main CTA per email
   - Personal, conversational tone
   - Include specific examples

3. **Frequency**
   - Weekly is optimal for engagement
   - Consistent day/time builds habit
   - Quality over quantity

4. **Voice**
   - First person, conversational
   - Share genuine experiences
   - Admit when learning
   - No corporate speak
