Newsletter Subject Lines

The 3-Phase Workflow

Phase 1: Identify Core Value

• What's the most surprising insight?
• What problem does this solve?
• What will readers learn they didn't know?
• What would make someone forward this?

Phase 2: Generate 10+ Options

references/10-commandments-checklist.md

• Try 3-4 different patterns
• Apply sticky techniques from

  references/sticky-sentence-techniques.md

• Test with/without numbers

Phase 3: Evaluate & Select

references/newsletter-subject-lines-analyzed.md

• Score top 5-7 options with 10 Commandments (aim for 4-6)
• Use 4 U's test (Useful, Urgent, Unique, Ultra-specific)
• Final check: Would YOU open this? Would Sarah forward it?

Core Patterns (With Examples)

1. Number + Why

• "Why 1.5 million students are in microschools now"
• "83% of parents agree: schools aren't preparing kids for AI"
• "The $1,200 your ESA can actually cover"

2. Contrast / This vs That

• "The gap that matters isn't algebra. It's initiative."
• "Small schools. Big difference."
• "Credentials vs Community: What actually helps kids thrive"

3. Contrarian Truth

• "You don't need permission to start a school"
• "The other kind of testing (the one that actually works)"
• "What if school just... ended earlier?"

4. Curiosity Gap

• "What public schools don't want you to know"
• "The education trend public schools fear"
• "The real reason homeschool kids outperform"

5. Named Person + Insight

• "Ken Danford quit teaching to prove schools are optional"
• "What Jason Skycak learned tutoring 10,000 hours"
• "She homeschools 5 kids and runs a business. Here's how."

6. Challenge + Data

• "Half of Prenda's guides have no credentials. Here's why it works."
• "Students who test themselves retain 80% more. Schools still don't do it."
• "4-day school weeks work. 900 districts prove it."
