Promotional Email Writer

Purpose

This skill generates complete promotional email copy for marketing campaigns — subject lines, preview text, body copy, and CTAs — across multiple campaign types: product launches, flash sales, abandoned cart recovery, newsletters, seasonal campaigns, and email drip sequences. Every output is structured for conversion and includes CAN-SPAM/GDPR compliance checks. Unlike social media skills, this is purpose-built for the email channel with its unique constraints: preview pane optimization, deliverability concerns, and legal compliance requirements.

Triggers

  • "写营销邮件"
  • "promotional email"
  • "email subject line"
  • "abandoned cart email"
  • "newsletter copy"
  • "邮件营销"
  • "email drip sequence"
  • "邮件A/B测试"
  • "促销邮件"
  • "email campaign"

Workflow

  1. Receive campaign context from user: campaign type (launch/sale/abandoned cart/newsletter/seasonal), product details, target audience, and email goal.
  2. Generate subject line(s) optimized for open rate: under 50 characters, preview-pane friendly, no deceptive language.
  3. Write preview text that complements (not repeats) the subject line.
  4. Structure body copy for scannability: headline → greeting → hook paragraph → product value → offer details → urgency (ethical) → CTA button → footer.
  5. Craft primary CTA button copy with clear action language.
  6. Include unsubscribe mechanism language and sender identity in footer.
  7. Run compliance review: deceptive subject line check, missing unsubscribe check, misleading claim check.
  8. Deliver complete email ready for ESP (Email Service Provider) upload.

Prompt Templates

1. Full Email (full_email)

Purpose: Generate a complete promotional email from campaign context. Input:

  • ${campaign_type} — launch / flash_sale / seasonal / newsletter / re-engagement
  • ${product_name} — Product or offer
  • ${promotion_details} — Discount, bundle, or offer specifics
  • ${target_audience} — Subscriber segment
  • ${brand_voice} — Tone: formal / casual / playful / luxury

Output: Complete email: Subject Line | Preview Text | Body Copy (with sections) | CTA Button | Footer (with unsubscribe).

2. Subject Line A/B (subject_line_ab)

Purpose: Generate subject line variants for open rate testing. Input:

  • ${campaign_context} — Brief campaign description
  • ${audience_segment} — Who is receiving
  • ${count} — How many variants (default 5)

Output: 5 subject lines labeled by approach (curiosity, benefit, urgency, personalization, question) with character counts and predicted open-rate rationale.

3. Email Sequence (email_sequence)

Purpose: Design a multi-email drip sequence for a customer journey stage. Input:

  • ${journey_stage} — Welcome / Nurture / Abandoned cart / Post-purchase / Win-back
  • ${product_name} — Product or brand
  • ${sequence_length} — Number of emails (typically 3–5)

Output: Email sequence table: Email # | Timing | Subject | Body Summary | CTA | Goal.

4. Abandoned Cart Email (abandoned_cart_email)

Purpose: Generate a recovery email for cart abandoners. Input:

  • ${product_name} — Item(s) left in cart
  • ${cart_value} — Total cart value
  • ${abandonment_window} — Hours since abandonment
  • ${incentive} — Optional discount or free shipping offer

Output: Recovery email with: gentle reminder subject, product image description placeholders, benefit recap, urgency (if incentive), CTA back to cart.

5. Email Compliance Review (email_compliance_review)

Purpose: Review draft email for deliverability and legal risks. Input:

  • ${email_draft} — Complete email: subject + body + footer
  • ${target_region} — GDPR (EU), CAN-SPAM (US), CASL (Canada), or PIPL (China)

Output: Compliance report: Check | Status (Pass/Flag) | Issue | Suggested Fix.

Output Format

Every full email follows this deliverable structure:

SUBJECT LINE: [under 50 chars]
PREVIEW TEXT: [complements subject, under 100 chars]

[BODY]
Header/Logo space
Headline
Greeting
Hook paragraph
Product/Offer section
Social proof (if applicable)
CTA Button → [Button text]
Urgency/Scarcity note (ethical)
Closing

[FOOTER]
Unsubscribe link language
Company info
Privacy policy link

Safety Rules

  • NEVER write deceptive subject lines (e.g., "Re: Your order" when it's not a reply, fake "Urgent" flags)
  • NEVER make misleading discount claims or hidden conditions
  • NEVER omit unsubscribe mechanism language — it must be clearly present
  • ALWAYS include proper sender identity (company name, physical address for CAN-SPAM)
  • ALWAYS remind user about GDPR consent requirements for EU subscribers
  • ALWAYS flag potential spam-trigger words in subject lines (e.g., "FREE!!!", "ACT NOW!!!")

Examples

Example 1: Full Email for Flash Sale

Input: Campaign="618大促", Product="XX护肤品套装", Discount="满300减50", Audience="女性25-40岁", Voice="亲切温暖" Output: Subject "你的618专属护肤清单来了 ✨", preview "满300减50，这套搭配我们准备了很久", body with hero image placeholder, product trio showcase, discount breakdown, countdown urgency, CTA "立即抢购", full footer.

Example 2: Abandoned Cart

Input: Product="一双运动鞋 ¥499", Cart value="¥499", Abandonment="24小时", Incentive="包邮" Output: Subject "它还在等你 👟 — 免邮提醒", gentle reminder tone, product benefit recap, free shipping highlight, CTA "回到购物车".
