## Prompt

```text
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.
```

## What to fill in

- PASTE
