Email Campaign Skill

This skill writes complete, sequenced email campaigns — from welcome flows to product launches to re-engagement sequences. Each email is written with subject line, preview text, full body copy, and CTA.

Required Inputs

Ask the user for these if not provided:

• Campaign goal (onboard new users / launch a product / nurture leads / re-engage churned users / announce a feature)
• Audience (who receives this? job title, lifecycle stage, what they know already)
• Product or offer being promoted or introduced
• Number of emails in sequence (if unsure, recommend based on goal)
• Tone (professional / conversational / bold / educational)
• Sender name (person or brand?)

Sequence Recommendations by Goal

If the user hasn't specified number of emails, use these defaults:

• Onboarding: 4 emails over 7 days (Day 0, Day 1, Day 3, Day 7)
• Product launch: 3 emails (Teaser → Launch Day → Follow-up/Last chance)
• Lead nurture: 5 emails over 2 weeks
• Re-engagement: 3 emails (Gentle nudge → Value reminder → Final offer)
• Feature announcement: 2 emails (Announcement → How-to/deep dive)

Output Structure Per Email

For every email in the sequence, produce:

---

Email [N] of [Total] — [Descriptive label e.g. "Welcome / Day 0"] Send timing: [When relative to trigger event or previous email]

Subject line: [Primary option] Subject line (A/B variant): [Alternative to test] Preview text: [40–90 characters — adds context to the subject, doesn't repeat it]

Body:

[Full email copy — formatted with clear opening line, 2–3 body paragraphs, one primary CTA]

CTA button text: [3–6 words] CTA destination: [What page/action this should link to]

Strategic note: [Why this email does what it does — the psychological or strategic intent. 1–2 sentences.]

---

Writing Rules

• Opening line must earn attention — no "Hi, welcome to [product]" openers
• Each email has ONE primary CTA — never two competing asks
• Keep paragraphs to 2–3 sentences maximum for mobile readability
• Use "you" more than "we" — centre the reader, not the brand
• Subject lines under 50 characters perform best on mobile — flag if going over
• Preview text should add information the subject doesn't — never just repeat it
• Every email should stand alone — assume some subscribers miss earlier emails

Quality Checks

• Each email has a single clear CTA
• Subject lines are under 50 characters (or flagged)
• Preview text doesn't repeat the subject line
• Opening line is specific and attention-earning
• Sequence has logical narrative arc (doesn't feel like disconnected blasts)
• Tone is consistent across all emails
• Strategic notes explain the intent of each email

Anti-Patterns

• Do not include more than one primary CTA per email — competing calls to action reduce click-through by splitting attention
• Do not open with "Hi, welcome to [product]" or any variation of a generic greeting — the opening line must earn attention immediately or recipients stop reading
• Do not write preview text that repeats the subject line — preview text is a second chance to earn the open, not a repeat of the first chance
• Do not write a sequence where each email restates the same value proposition — each email must advance the narrative or serve a distinct purpose in the buyer's journey
• Do not assume all subscribers receive all emails — each email must stand alone for subscribers who missed earlier messages in the sequence

Example Trigger Phrases

• "Write a 3-email launch sequence for [product]"
• "Build an onboarding email flow for [SaaS tool]"
• "Create a drip campaign to nurture leads for [offer]"
• "Write a re-engagement campaign for churned users"
