Ran our June campaign through this and got 10 subject line pairs where the preview text continues the thought instead of repeating it
Generates subject line and preview text pairs engineered as one unit — the preview continues or twists the subject instead of repeating it.
Subject Line + Preview Text Pairs That Work Together
You are an email marketer writing subject lines and preview text as a single unit. The inbox shows them side by side — treat them as setup and payoff, never as two versions of the same sentence.
Email content (full body or summary):
{{email_body}}
Audience segment and what they've received recently: {{segment}}
Brand voice: {{voice}}
The one action this email exists to drive: {{goal}}
Generate 10 subject + preview pairs. Constraints:
1. **Subject ≤ 45 characters** (mobile truncation), **preview ≤ 80 characters**. Show counts.
2. **The pair test:** cover the subject and read only the preview — it must still add information. Cover the preview and read the subject — it must create a specific curiosity, not vague mystery. Reject and rewrite any pair failing either direction.
3. **Spread across 5 mechanisms, 2 pairs each:**
- Specific number or fact from the email body
- Question the body genuinely answers
- Contrast/tension (before–after, expectation–reality)
- Direct value statement (what they get, plainly)
- Pattern interrupt (unusual angle — but never misleading about content)
4. **Honesty check:** every pair must be fully redeemed by the email body. A subject the body can't cash is marked SPAM-ADJACENT and replaced.
5. No emojis, no ALL CAPS words, no "quick question", no fake RE:/FW:.
Output as a table: # | subject (chars) | preview (chars) | mechanism | why this pair works — one line.
Then recommend the 2 pairs to A/B test first and what each test would actually teach us.

## Subject + preview pairs — June feature announcement
| # | Subject (chars) | Preview (chars) | Mechanism | Why it works |
|---|---|---|---|---|
| 1 | Your reports now build themselves (33) | Set the schedule once. Every Monday, it's just there. (53) | value | Preview answers the how the subject implies |
| 2 | 4 hours back, every single month (32) | That's what auto-reports save our average customer. (51) | number | Subject makes the claim, preview sources it |
| 3 | The Monday task nobody will miss (32) | Manual reporting retires this week. Here's what replaces it. (60) | contrast | Subject teases, preview names the retiree |
| 4 | Still building reports by hand? (31) | As of today, that's officially optional. (41) | question | Preview is the punchline, not a repeat |
| 5 | We watched you export CSVs. Sorry. (34) | The feature that ends the Tuesday spreadsheet ritual is live. (61) | interrupt | Slightly cheeky, fully redeemed by body |
| 6 | What 312 beta users asked us to keep (36) | Not the dashboard. Not the charts. This one setting. (52) | number | Specific count + preview narrows the mystery |
| 7 | Reports on autopilot, starting now (34) | Pick a schedule, pick recipients, done. Live in your account. (61) | value | Plain and complete; preview confirms availability |
| 8 | Before: 40 clicks. After: zero. (31) | Auto-reports just went live for your plan. (42) | contrast | Numbers carry it; preview grounds it |
| 9 | Why did Tuesday get quieter? (28) | Because your first automated report went out this morning. (58) | question | Works especially for the segment already opted into beta |
| 10 | Your calendar won't notice. Your team will. (43) | Automated reports: invisible effort, visible Mondays. (53) | interrupt | Twist on the time-saving frame without repeating it |
All pairs pass the cover test in both directions. One rejection during drafting: "You'll never report again" — SPAM-ADJACENT, the body only automates scheduled reports, ad-hoc reporting remains manual. Replaced by #7.
## Test first
- **#2 vs #7** — same value proposition, number-led vs plain-statement. Teaches whether this segment responds to quantified claims or direct clarity; that answer transfers to every future send.
- **#5 vs #3** — cheeky vs safe on the same contrast frame. June is the right month to learn your tolerance for personality while list fatigue is low; if #5 wins on opens but loses on clicks, you've learned the personality attracts but doesn't convert — cap it at subject-line use.
Skip testing #9 broadly — it only fully lands for the beta cohort; send it to them as a segment-exclusive instead.

The cover-both-directions test is going straight into my checklist. So simple and nobody does it.
