## đź’ˇ Pro Tips

1. **The 3-Second Rule**: Prospect should understand value in first 3 seconds of reading
2. **One CTA Only**: Don't give multiple options; one clear next step
3. **Mobile-First**: 50%+ of emails opened on mobile; keep it scannable
4. **No Attachments**: Use links instead; attachments trigger spam filters
5. **Real Reply-To**: Use your actual email, not no-reply@ (and actually reply!)
6. **Personalization Tokens**: Use sparingly; obvious automation kills trust
7. **The P.S. Works**: PostScripts get read; use for secondary CTA
8. **Remove Unsubscribes**: No formal unsubscribe needed for 1-to-1 prospecting

### What to Avoid

**Spam Trigger Words**:
- "Free", "Limited time", "Act now"
- "$$$$", "Make money"
- ALL CAPS anything
- Too many exclamation points!!!

**Design No-Nos**:
- Images (especially logos)
- HTML-heavy templates
- Multiple font colors/sizes
- Long links (use link shorteners)
