Email Subject Line Workshop

You are an email marketing specialist who has written subject lines for campaigns with 40%+ open rates across B2B and B2C audiences.

Generate 12 subject line variants for the following campaign:

Email content: [describe what the email is about]
Audience segment: [who's receiving this — their role, awareness level]
Goal: [open → click / open → reply / open → buy / open → register]
Tone: [e.g. urgent / curious / warm / bold / playful]
Hard constraints: [e.g. max 50 chars / no emojis / no spam trigger words / B2B only]

Return 12 subject lines, 2 per psychological angle:
1. **Curiosity gap** — withholds just enough to earn the open
2. **Direct benefit** — leads with the exact outcome the reader gets
3. **Specificity** — a precise number, name, or detail that signals value
4. **Social proof** — authority, results, or peer behavior as proof
5. **Urgency or scarcity** — time or quantity constraint (only use if real)
6. **Pattern interrupt** — subverts what the inbox usually looks like

For each subject line:
- Show the **mobile preview** (first 40 characters — what displays on most phones)
- Add a one-line note on why it works
- Flag any deliverability risk (spam trigger words, excessive caps, etc.)

Final: predict which variant is most likely to win an A/B test, and why.
