Quick Answer: Provide ChatGPT with your target audience details, specify your email's goal, and ask for 10+ subject line variations using different emotional triggers like urgency, curiosity, or social proof.
Email subject lines determine whether your carefully crafted message gets opened or ignored. With average open rates hovering around 20-25%, your subject line is the make-or-break element of any email campaign.
ChatGPT offers a fast, cost-effective way to generate and test multiple subject line approaches before hitting send. Instead of relying on guesswork or A/B testing with real audiences (which takes time and splits your list), you can validate subject line effectiveness instantly.
Before asking ChatGPT for subject lines, provide detailed audience information:

The Buyers Table allows you to:

"I'm targeting three different segments with this email: new leads, trial users, and existing customers. Create 5 subject lines tailored to each segment's mindset and relationship with our brand."
"My audience is skeptical about [specific concern]. Create subject lines that acknowledge this skepticism while building curiosity about our solution."
"Adapt these 3 subject lines for different industries: healthcare, manufacturing, and financial services. Adjust the language and priorities for each sector."

Instead of choosing subject lines based on personal preference or internal team opinions, you can test each variation against AI personas built from your actual customer data. These virtual buyers will flag potential issues like:
