Generates and ranks email subject lines with psychological reasoning. Boosted my open rates by 34%.
I need email subject lines that actually get opened. Here's my situation: Email content: [WHAT THE EMAIL IS ABOUT] Audience: [WHO WILL RECEIVE IT] Goal of the email: [CLICK / REPLY / PURCHASE / READ] Current average open rate: [X%] Write 15 subject line variations across these categories: - **Curiosity gap** (3 lines) - **Benefit-driven** (3 lines) - **Urgency/scarcity** (2 lines) - **Personalization hooks** (2 lines) - **Contrarian/surprising** (3 lines) - **Ultra-short** (under 4 words) (2 lines) For each, predict the open rate relative to my baseline (e.g., "+15%") and explain the psychology behind it. Then rank your top 3 for an A/B test.
