Market Emails

Market Emails — Sequence Writer

Produce full, send-ready email sequences. Every email has a purpose, every sequence has a goal, every send has a metric target.

Sequence Types

| Type | Goal | Length | Cadence | |---|---|---|---| | Welcome | Activate new signups | 5–7 emails | Day 0, 1, 3, 5, 7, (10, 14) | | Nurture | Convert warm leads to buyers | 6–8 emails | Every 2–3 days | | Launch | Drive sales for a new product | 5–7 emails | 14 days: tease → reveal → proof → urgency → cart close | | Cold outreach | Start B2B conversations | 4–6 touches | Day 0, 3, 7, 14, 21, 30 | | Cart abandon | Recover lost revenue | 3 emails | 1h, 24h, 72h | | Re-engagement | Wake inactive subscribers | 3–4 emails | Every 3–4 days | | Onboarding | Drive product activation | 5–6 emails | Triggered on signup + milestones |

Benchmarks (2024+)

| Metric | B2B | B2C | E-com | |---|---|---|---| | Open rate | 25–35% | 20–30% | 18–25% | | Click rate | 2–5% | 2–4% | 2–5% | | Reply rate (cold) | 3–10% | — | — | | Unsubscribe | <0.5% | <0.5% | <0.5% | | Cart recovery | — | — | 10–25% |

Subject line failure = open rate < benchmark. CTA failure = click rate < benchmark. Offer failure = conversion below expected.

Subject Line Formulas

| Formula | Pattern | Example | |---|---|---| | Curiosity | Tease without revealing | "The reporting mistake we all made" | | Specificity | Number + outcome | "How Jamie cut reports from 8h to 20min" | | Personal | First name + context | "{{first_name}}, a quick question" | | Contrarian | Challenge common belief | "Stop A/B testing your headlines" | | Question | Prompt self-reflection | "Is your funnel actually a funnel?" | | Urgency | Real deadline | "Last day for the 2025 rate" | | Social proof | Show outcome | "5,000 teams use this now" | | Fear of missing out | What others know | "What growth teams are doing in Q2" | | Pattern interrupt | Unexpected framing | "Ignore this if you're already ranking" | | Plain text-style | No marketing gloss | "quick question about acme" |

Always ship 3 subject line variants per email so the client can A/B test.

Pre-flight

1. Load BRAND-VOICE.md if present; match tone.
2. Confirm the goal, audience, and product/offer.
3. Confirm cadence and sending platform (affects formatting — Mailchimp vs SendGrid vs HubSpot all render differently).
4. Ask for a "from" name and reply-to — it matters more than people think.

Email Anatomy

Every email includes:

• From name (real human preferred over "Acme Team")
• Subject line (3 variants)
• Preview text (40–90 chars, complements subject)
• Body (plain-text-friendly when possible)
• Primary CTA (1 per email; secondary only in nurture/launch)
• PS (often the second most-read line in the email)

Body structures

| Position | Function | |---|---| | Opening line | Hook — curiosity, relevance, story start. Never "Hi {{name}}, I hope this email finds you well." | | Setup | Context — why this matters to them, what they'll get | | Payoff | The actual value — insight, offer, story, proof | | CTA | Clear next step, value-driven, linked once or twice max | | Signature | Real name, human | | PS | Restate value, add urgency, or surface a secondary offer |

Compliance (do not skip)

• CAN-SPAM (US): physical address, unsubscribe link, truthful headers, honor unsubs in 10 days
• GDPR (EU): explicit consent, unsubscribe, data purpose disclosed
• CASL (Canada): express consent for cold outreach; implied consent only in narrow cases
• Cold outreach specifically: include why you're reaching out, who you are, and an easy opt-out

Every sequence output must include a compliance note stating which regions it's cleared for.

### Email 2: ...

Cold Outreach (special case)

Cold emails need extra care. Use this structure for every touch:

• Touch 1 (Day 0): Personal observation + specific problem + light CTA ("worth a quick chat?")
• Touch 2 (Day 3): Value drop — share an insight or resource, no ask
• Touch 3 (Day 7): Social proof — similar company outcome
• Touch 4 (Day 14): Direct ask with clear offer
• Touch 5 (Day 21): Breakup — "should I close the loop?"
• Touch 6 (Day 30, optional): New hook, different angle

Never send a 500-word first email. Cold outreach above 120 words dies.

Quality Bar

• Read every email aloud. If it sounds like a template, rewrite.
• Personalization tokens are not personalization. A real observation is.
• Never promise a discount you can't deliver. Never fake scarcity.
• If the user can't point to a real outcome or proof, the sequence will fail no matter how good the copy is — say so.
