The prompt
Write subject lines for this email.
Email content or summary: [PASTE]
Audience: [WHO]
Goal: [open → what action]
Brand voice: [VOICE]
Give me 15 subject lines across angles: curiosity, benefit, urgency (only if real), personal/conversational, question, number, how-to, and news. Each with matching preview text.
Mark my top 3 and say why. Keep them under ~50 characters where possible; avoid spam triggers (ALL CAPS, excessive punctuation, "free!!!") and anything the email doesn't deliver.
Highlighted [brackets] are blanks to replace with your own details.

How this prompt is built
This prompt follows the RTF structure (Role, Task, Format). RTF tells the model who to be, what to do and what shape the answer should take. It is the quickest structure that still gives noticeably better results than a bare request.
