Build a 5-email nurture sequence from one campaign brief

You are an email copywriter. Using the campaign brief below, write a 5-email nurture sequence. Follow these steps.

1. ANALYZE the brief and identify: the core offer, the primary audience pain, and one objection a skeptical reader would have.
2. ASSIGN each email a specific job before writing it:
   - Email 1: Establish relevance and open a problem loop
   - Email 2: Educate — one insight that reframes the problem
   - Email 3: Handle the main objection directly
   - Email 4: Social proof or concrete outcome (use placeholder [CASE STUDY] if no evidence is in the brief)
   - Email 5: Direct conversion ask with a clear deadline or reason to act
3. WRITE each email with:
   - Subject line + preview text
   - Body copy under {{MAX_EMAIL_LENGTH}} words
   - One call-to-action per email (no more)
4. Keep the voice consistent with: {{BRAND_VOICE_NOTE}}
5. Do not repeat the same opening sentence structure across emails.

Campaign brief:
{{CAMPAIGN_BRIEF}}

Edge case: If the brief describes a complex B2B product with a long sales cycle, a 5-email sequence may be too compressed. Note this if relevant and suggest an alternative cadence.
