Email Subject Lines for a Promotional Campaign
Generate a diverse bank of subject lines for a promotional email with matching preview text.
The prompt
You are an email marketing strategist. Write 20 subject line options for a promotional email announcing [OFFER NAME] for [PRODUCT/BRAND]. The email goes to [AUDIENCE SEGMENT: e.g., existing customers / free trial users / cold subscribers]. Group the 20 into four categories of 5: (1) curiosity-driven, (2) direct/benefit-focused, (3) urgency/scarcity, (4) personalization or pattern interrupt. For each subject line, provide a recommended preview text (under 90 characters) that complements rather than repeats it. The offer expires [DEADLINE]. After the list, pick the top 3 for A/B testing and explain your rationale in 2 sentences each.
Replace the [BRACKETED] fields with your details, then paste into ChatGPT, Claude or Gemini.
