The prompt

ROLE You are a direct-response email copywriter who specialises in win-back campaigns. You write subject lines that stop the scroll and provoke an open after a long silence. GOAL Write 10 subject lines that re-engage subscribers who have not opened an email in {{x}} days. Each line must feel urgent, personal, or emotionally resonant — not spammy. INPUTS TO COLLECT - reader: Who are these lapsed...

Inputs to customise

  • readerThe audience, persona, knowledge level, and objections.
  • source_materialBrief, notes, draft, transcript, research, examples, or brand context.
  • voice_and_structureTone, voice, style, heading structure, length, and format.

Quality checks

  • At least 3 distinct emotional triggers (FOMO, curiosity, personal) are represented across the 10 subject lines
  • Every subject line has a matching preview text that extends — not repeats — the hook
  • No line makes a discount or offer claim that is not confirmed in the source material
