HOW TO USE THIS SKILL

When the user provides a request, follow this workflow:

Step 1 — Classify the Request

Determine which type of email work is needed:

• Write an email — draft copy for a specific email type
• Build a sequence/flow — design a multi-email automation
• Audit/review — analyse existing emails or setup
• Strategy — advise on approach, platform, or benchmarks
• Deliverability — diagnose or fix inbox placement issues
• Cold email — B2B outbound strategy and copy

Step 2 — Gather Context (if not provided)

Before writing, confirm:

1. Goal — what should the reader DO after reading?
2. Audience — who is this for? (segment, industry, lifecycle stage)
3. Voice/brand — formal, casual, bold, warm?
4. Type — which email type (welcome, cart, promo, cold, newsletter, etc.)?
5. Constraints — word count, CTA, offers, compliance needs?

If the user's request is clear enough, skip asking and proceed.

Step 3 — Write Using the Knowledge Base Below

Apply the frameworks, benchmarks, and expert principles from this skill file. Every email you write should demonstrate mastery of the principles below.

Step 4 — Output Format

Deliver:

1. Subject line (+ 2 alternatives for A/B testing)
2. Preview text
3. Email body (formatted, ready to paste)
4. Notes — why you made the choices you did, which frameworks you applied, and any recommendations

1. FUNDAMENTALS

Why Email Wins

• ROI: $36 per $1 spent (3,600%). Newsletter-as-business: 122%. Social: 28%. Paid search: 25%.
• 89% of marketers use email as primary lead gen channel. 51% of consumers prefer email from brands.
• Email is owned media — no algorithm throttling, no platform risk.
• Multi-channel subscribers drive 50% higher purchase rates and LTV vs single-channel.

The Email Stack (6 components)

1. ESP — sending platform (Klaviyo, Mailchimp, etc.)
2. Authentication — SPF, DKIM, DMARC. Non-negotiable since Feb 2024 Google/Yahoo rules.
3. List management — quality > size. 5K engaged beats 50K messy.
4. Content & design — 60%+ opens on mobile. Mobile-first is essential.
5. Automation — flows generate 30x more RPR than campaigns. Set up flows before campaigns.
6. Analytics — 21% of marketers don't measure ROI. Don't be one of them.

Key Metrics & Benchmarks

Post-Apple MPP: Open rates are directional only. Use click-based metrics as primary.

Tags vs Segments vs Lists

• Lists: Use ONE master list. Multiple lists = duplicate subscribers, inconsistent data.
• Tags: Labels on subscribers (facts). Applied manually or via automation.
• Segments: Dynamic groups based on rules. Auto-update as conditions change.
• Minimum segments: new (last 30 days), engaged (clicked last 60 days), customers vs non-customers, lapsed (90+ days).

2. LIST BUILDING

Organic Growth

• Lead magnets: Templates/swipe files convert highest. Free template increased signups by 384%.
• Content upgrades: 5-10x better opt-in vs generic sidebar forms.
• Signup forms: Form > link (20-50% more opt-ins). "Get my templates" > "Subscribe" (33% lift).

Popups

• Well-timed popups: 3-5% conversion. Top 10%: 9.28%.
• Exit-intent: 4-7%. Two-step popups: 30-50% better than
