Email Subject Line Examples by Scenario (All Scored)
Example libraries are usually unmetered — a hundred lines, no way to tell the good from the loud. Every line below carries its score from this site's ten-check engine, and the scenario rows name the check doing the work. Copy the shape, swap your nouns, and run your version through the tester before sending.
Quick answer: Scored examples by scenario: announcement 'Say hello to the new dashboard' (72/100), promo '30% off — this week only' (65), re-engagement 'Still thinking it over?' (66), cold outreach 'A 2-minute idea (no deck)' (68), habit 'Your Q4 plan: 2 spots left this month' (81). Scenario first, mechanism second, words last.
Announcements & launches
The job: novelty without hype. Lead with the new thing, keep punctuation calm.
| Subject line | Score | Check doing the work |
|---|---|---|
| Say hello to the new dashboard | 72 | Warm verb + concrete product; no exclamation needed |
| New: the new dashboard is live | 72 | 'New:' prefix format — instant novelty signal |
| Introducing the new dashboard | 72 | Launch framing in one word |
| You asked, we built it | 68 | Story frame — credits the reader with the idea |
| Small change, big difference | 65 | Antithesis rhythm; honest for feature updates |
Promo & e-commerce
The job: specify the offer fully and honestly — discount, window, and what — without tripping the spam list.
| Subject line | Score | Check doing the work |
|---|---|---|
| 30% off — this week only | 65 | Number + deadline; the offer completely specified |
| Back in stock (finally) | 67 | Pattern interrupt; spoken-voice aside |
| You left something behind | 68 | Second person + curiosity; the cart-abandonment classic |
| 48 hours of beta access | 68 | Concrete window; scarcity with a real clock |
| Because you asked: 30% off | 78 | Justification word + number |
Cold outreach & services
The job: relevance plus a tiny ask, from a sender the reader doesn't know yet.
| Subject line | Score | Check doing the work |
|---|---|---|
| Quick question about deep work | 72 | Question frame + their topic |
| A 2-minute idea (no deck) | 68 | Prices the read; removes the pitch fear |
| Noticed something about deep work | 65 | Observation framing — homework implied |
| Should I send the checklist? | 71 | Permission-based yes/no ask |
| Worth a look, team-to-team | 65 | Peer framing lowers the vendor guard |
Re-engagement & win-back
The job: a soft, human line for someone who's gone quiet — no guilt, no ALL-CAPS desperation.
| Subject line | Score | Check doing the work |
|---|---|---|
| Still thinking it over? | 66 | Empathy question; zero pressure in four words |
| A little thank-you for you | 73 | Warmth play — gratitude instead of a demand |
| The wait is over | 50 | Loop closure for something they signed up for |
How to use this library honestly
The scores above were run against the engine exactly as shown — the moment you swap in your nouns, the score moves (usually up, when you add specificity). Three rules make the library work: copy the shape, not the words (your 'new dashboard' is someone else's 'spring menu'); re-score after editing (the tester takes ten seconds and catches the spam word you imported with your noun); and when two finalists tie within a couple of points, pick the one that sounds like you — the checklist is deliberately indifferent about voice.
What SubjectLines doesn't do
- No '537 subject lines your competitors stole' — every line here is scored and explainable.
- No open-rate promises; scores are checklist grades, not oracle readings.
