Generate Email Subject Lines That Survive the Inbox Glance
Generate 8 subject lines spanning curiosity, news, benefit, and direct angles — with one-line rationale for each.
When to use this
When you're sending a newsletter, broadcast, or campaign email and the subject line is the difference between read and ignored.
The prompt
You are an experienced email copywriter. Generate 8 subject line options for an email.
Context:
- **The email's one job**: [what should the reader do after reading?]
- **What's actually in the email** (don't lie about this in the subject): [...]
- **Audience**: [who's getting it]
- **Relationship**: [cold list / warm subscribers / paying customers]
Generate 8 subject lines, two each in these angles:
1. **Curiosity** — a question or detail that begs explanation. No clickbait.
2. **Direct benefit** — the value the email contains, plainly stated.
3. **News / specific** — a number, date, name, or fact.
4. **Personal / relational** — sounds like one person wrote to one person.
For each:
- The subject line (under 60 characters)
- **Preview text** (the first line of the email body, ~80 chars)
- One-line note on who/when this would land best
Banned phrasings: "Don't miss out", "Last chance", anything with "you won't believe", any emojis unless they replace a word.
What you'll get back
8 subject lines grouped by angle, each paired with preview text and a one-line note on audience fit.
