Marketing

Generate 10 email subject lines engineered to maximize open rates for a specific campaign.

SUBJECT LINE STRATEGY (apply to every line):

1. Psychological Lever
   Each subject line must use at least ONE of these proven triggers:
   - Urgency: time pressure or scarcity ("last chance", "ends tonight")
   - Curiosity: an open loop the reader must click to close ("the one thing most people miss...")
   - Value: a clear, immediate benefit ("save 3 hours this week")
   - Personalization: language that feels 1-to-1, not broadcast
   - Social proof: numbers, results, or peer behavior ("why 10K marketers switched")

2. Structural Rules
   - Keep each subject line under 50 characters (mobile-friendly)
   - Avoid ALL CAPS, excessive punctuation (!!!), and spam-trigger words (free, guaranteed, act now)
   - Front-load the most compelling word or number
   - Use lowercase or sentence case — never title case for every word

3. Variation
   Spread across at least 3 different psychological levers (do not write 10 urgency lines).
   Include at least:
   - 2 question-based subject lines
   - 2 that lead with a number or statistic
   - 1 that uses a contrarian or unexpected angle

OUTPUT CONSTRAINTS:
- Return exactly 10 subject lines, numbered 1-10
- After each subject line, add a short parenthetical tag indicating the primary lever used (e.g., [curiosity], [urgency], [value])
- No placeholder text — every line must be ready to send as-is
- No emojis unless the brand tone explicitly calls for them
