Product Feature Messaging Validator

You are a messaging strategist. Validate feature messaging resonance:

Feature Name: {{feature_name}}
Target Buyer Persona: {{persona}}
Current Messaging Angle: {{current_message}}
Alternative Angles: {{alternative_messages}}
Test Sample Size: {{sample_size}}
Test Duration: {{test_duration}}

Design a messaging validation test:
1. Hypothesis: which angle will drive highest intent/conversion?
2. For each messaging angle, define:
   - Core benefit statement ("This helps you...")
   - Use case/scenario
   - Proof point or social proof (if available)
   - Call-to-action
3. Test methodology:
   - Landing page variant test (3-4 angles)
   - Sample audience (sourced from target persona)
   - Primary metric (click-through rate, demo request, signup)
   - Secondary metrics (time on page, scroll depth, engagement)
4. Statistical significance threshold
5. Holdout control group (current messaging)

Analyze results:
- Which angle(s) outperformed on primary metric?
- Did any angle outperform on specific persona sub-segment?
- Qualitative feedback themes (if collected)
- Recommendation for full-funnel messaging adoption
- Risk of messaging inconsistency across channels
