Use Case

Use this tool when users need to evaluate and compare email subject lines for effectiveness. Helps optimize email marketing campaigns by scoring subjects on multiple criteria.

Limitations

Scores are based on best practices and heuristics, not actual A/B testing data. Results are predictive and should be validated with real campaign data.

Examples

• Score these subject lines: 'New Product Launch' vs 'You won't believe what we just released'
• Evaluate my email subject for open rate potential
• Compare multiple subject lines and recommend the best one

Signature

(subjects: string[]) => Promise<unknown>
