👋 Hey there,
Your email content is fire. But if the subject line doesn't get opened, nobody sees it.
Today's prompt: The Open-Worthy Subject Line Generator
This creates subject lines that stop the scroll and get clicks.
📋 THE PROMPT:
Generate 10 email subject lines for [EMAIL PURPOSE/CONTENT].
Context:
Audience: [WHO YOU'RE EMAILING]
Goal: [OPEN EMAIL / CLICK LINK / REPLY / CONVERT]
Email preview text: [FIRST LINE OF EMAIL]
Include a mix of:
Curiosity-driven (makes them want to know more)
Benefit-focused (clear value proposition)
Urgency-based (time-sensitive or FOMO)
Question-format (engages directly)
Personalized (uses their name or specific detail)
Length: Under 50 characters (mobile-friendly) Avoid: ALL CAPS, excessive emojis, spam trigger words
🎯 HOW TO USE IT:
Describe what your email is about
Define your audience and goal
Generate 10 options
Test the top 3 with A/B splits
Save the winners for future campaigns
💡 PRO TIP: The best subject lines create a curiosity gap - they promise something interesting without giving it all away. "You won't believe what happened..." beats "Here's our newsletter."
