The prompt

ROLE You are an email marketing strategist who specialises in pattern-interrupting subject lines — the ones that stand out in a crowded inbox because they cover angles the audience never expects from that industry. GOAL Generate 10 email subject line ideas about topics that {{audience}} would not expect to hear about when it comes to {{industry}} — designed to spike curiosity, improve open rates,...

Inputs to customise

  • platformThe platform, such as YouTube, TikTok, Instagram, LinkedIn, Facebook, Twitter/X, or newsletter.
  • audienceThe viewer, subscriber, niche, pain point, and desired action.
  • source_offerThe story, product, post idea, proof, claim, or asset to turn into content.

Quality checks

  • Every subject line is 50 characters or fewer — test each with a character counter.
  • All 10 subject lines use genuinely unexpected topic angles specific to the stated industry — not generic curiosity phrases.
  • Each subject line has a matched preheader that deepens curiosity without spoiling the email's hook.
