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)
- ESP — sending platform (Klaviyo, Mailchimp, etc.). See Section 12.
- Authentication — SPF, DKIM, DMARC. Non-negotiable since Feb 2024 Google/Yahoo rules.
- List management — quality > size. 5K engaged beats 50K messy.
- Content & design — 60%+ opens on mobile. Mobile-first is essential.
- Automation — flows generate 30x more RPR than campaigns. Set up flows before campaigns.
- Analytics — 21% of marketers don't measure ROI. Don't be one of them.
Key Metrics & Benchmarks
| Metric | Good | Strong | Red Flag |
|---|---|---|---|
| Click-through rate | 2-3% | 4%+ | Below 1% |
| Click-to-open rate | 10-15% | 20%+ | Below 5% |
| Unsubscribe rate | Under 0.2% | Under 0.1% | Above 0.5% |
| Bounce rate | Under 2% | Under 1% | Above 3% |
| Spam complaint rate | Under 0.1% | Under 0.05% | Above 0.3% |
| List growth rate | 3-5%/month | 5%+/month | Negative |
| Delivery rate | 95%+ | 98%+ | Below 85% |
| Inbox placement | 85-94% | 94%+ | Below 70% |
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 single-step.
Double vs Single Opt-in
- Double opt-in recommended for most. Validates addresses, prevents bots/traps, GDPR-ready.
- Compromise: single opt-in for purchasers, double for lead magnets/popups.
List Hygiene & Spam Traps
- Lists decay 22-30% annually. Unengaged subscribers cost money AND hurt deliverability.
- Sunset flow: Reduce frequency → re-engagement series (2-3 emails) → suppress non-responders.
- Spam traps: Pristine (honeypots), recycled (abandoned addresses), typo (gnail.com), role-based (info@).
- Prevention: Double opt-in, real-time validation at signup, regular list cleaning, engagement-based sending.

3. SEGMENTATION & PERSONALISATION
Personalisation Hierarchy (most to least impactful)
- Behavioural: Product recs from browse/purchase history. Highest impact.
- Lifecycle: Different content for new, active, VIP, at-risk, lapsed.
- Dynamic content blocks: Different images/products per segment in one template.
- Send-time: Per-subscriber optimal timing.
- Location-based: Weather, events, timezone, nearby stores.
- Name/demographic: Fine as addition, not meaningful alone.
RFM Quick Start
Simple version: segment by recency of last purchase into 4 groups:
- Purchased last 30 days (active)
- 31-90 days ago (warm)
- 91-180 days ago (cooling)
- 180+ days ago (cold)
Engagement-Based Sending (highest-impact optimisation)
- Tier 1: Clicked last 30 days → every campaign
- Tier 2: Clicked last 60 days → 75% of sends
- Tier 3: Clicked last 90 days → best content only (50%)
- Tier 4: No engagement 90-180 days → re-engagement flow only
- Tier 5: 180+ days → sunset flow
- Results: 15-30% better open rates, 20-40% fewer complaints, revenue stays flat or increases.
Waterfall Segmentation (prevents "three emails in one day")
Priority: Abandoned cart → Post-purchase → Browse abandonment → Win-back → Promotional.

- Email 1 (1-4h): Simple reminder. NO discount.
- Email 2 (24h): Address objections. Reviews, shipping, guarantee.
- Email 3 (48h): Small incentive if margins allow. First-time abandoners only.
Post-Purchase Sequence
Immediately: Order confirmation → Day 2-3: Shipping → Day 7-10: Satisfaction check → Day 14: Review request → Day 21-30: Cross-sell → Day 25-30: Replenishment (consumables).
Win-Back (target 60-90 day inactive)
- "We miss you" → 2. Value offer → 3. Breakup email (highest reply rate) → 4. Confirmation + re-subscribe link.
BFCM Playbook (5 phases)
- Build List (Sep-Oct) → 2. Warm Up (Oct-early Nov, ramp send volume) → 3. Tease (2-3 weeks before) → 4. BFCM Window (BF-CM, daily sends, engaged first) → 5. Post-BFCM (Dec, thank you, cross-sell, shipping deadline email).
Consistency Beats Perfection
- Liz Wilcox: 20-minute newsletter framework. Email Staircase: Follower → Friend → Customer.
- Ian Brodie: email weekly minimum. 2-3 short emails/week > one monthly newsletter.

5. COPYWRITING

- Inverted pyramid: key message first. Short paragraphs. Write, then cut 30%.
- 3:1 ratio: three value emails per one promotional.
Copywriting Frameworks
- AIDA: Attention → Interest → Desire → Action. Best for promotional.
- PAS: Problem → Agitate → Solution. Best for cold email, B2B.
- BAB: Before → After → Bridge. Best for case studies.
- Soap Opera Sequence (Chaperon): Multi-email narrative. 70%+ open rates deep in sequence.
- 1-3-1 Newsletter: One big story + three shorter items + one CTA.
