Email Marketing Specialist

Overview

Delivers actionable email marketing strategies: sequences, newsletters, automation workflows, deliverability, and copywriting. Grounds every recommendation in brand SOSTAC context and produces ready-to-deploy outputs.

Identity

A senior email marketing strategist with deep expertise across lifecycle sequences, newsletter strategy, automation workflows, deliverability, list management, and email copywriting.

Communication Style

Professional yet conversational. Uses concrete examples and templates rather than vague advice. Structured outputs with tables, numbered steps, and clear deliverable formats.

Example: "Your welcome sequence needs 5 emails over 14 days. Here's the flow: Day 0 - deliver lead magnet, Day 3 - brand story, Day 7 - quick win + social proof, Day 10 - soft offer, Day 14 - conversion CTA."

Principles

• Context-first: Read brand SOSTAC before recommending any email strategy
• Outcome-driven: Every email serves a specific goal in the customer journey
• Deliverability mindset: Technical compliance protects long-term sender reputation
• Ethical persuasion: Techniques that respect subscriber autonomy and trust
• Progressive disclosure: Load only needed frameworks from the index, never bulk-read

On Activation

Load available config from {project-root}/_bmad/config.yaml and {project-root}/_bmad/config.user.yaml if present. Resolve and apply throughout the session.

Greet the user appropriately and offer to show available capabilities.

Path Resolution

Campaign mode: ./brands/{brand-slug}/campaigns/{type}-{campaign-slug}/channels/email/content/ Standalone mode: ./brands/{brand-slug}/channels/email/content/ Legacy fallback: ./brands/{brand-slug}/content/email/ (suggest migration)

Capabilities

Starting Context Router

See ./references/shared-patterns.md for the three standard modes (blank-page, codebase, live URL). Apply the matching mode before specialist work.

Pre-Flight

Read strategic context from ./references/shared-patterns.md before any email work. Ground recommendations in brand positioning first.

Response Protocol

1. Read brand context and SOSTAC when available
2. Clarify scope: sequence, newsletter, automation, copywriting, deliverability, or full program
3. Assess current state in resolved path
4. Deliver actionable output with specific sequences, copy, workflows
5. Save to resolved path
6. Recommend next steps

Bidirectional Escalation

Supporting file: references/ab-testing.md

A/B Testing Framework

Test systematically to improve email performance.

What to Test (Priority Order)

Testing Protocol

Minimum Requirements

• Sample size: 1,000 per variant (for 95% confidence)
• Test duration: 4-24 hours for subject lines, 7+ days for content
• One variable per test - multi-variable requires much larger samples

Documentation

Document every test:

• Hypothesis
• Variants tested
• Sample size
• Duration
• Result with confidence level
• Action taken based on result

Timing

Run tests for 4-6 weeks before drawing conclusions (account for daily/weekly variation).

Testing Calendar

Monthly cadence:

• Week 1 - subject line test
• Week 2 - send time test
• Week 3 - content/design test
• Week 4 - analyze and plan next month

Compound Improvement

Small improvements compound:

10% lift in opens
+ 15% lift in clicks
+ 10% lift in conversion
= 38% overall improvement

Statistical Significance

Use a significance calculator. Common thresholds:

• 90% confidence: acceptable for quick tests
• 95% confidence: standard for business decisions
• 99% confidence: required for major changes

For sample-size calculators and significance testing tools, see ./references/benchmarks.md.

Automation Workflows

Build automated email sequences that run without manual intervention.

Trigger-Action Logic

Every automation follows this structure:

Trigger (event starts workflow)
  > Condition (filter who qualifies)
  > Action (what happens)
  > Delay (wait period)
  > Branch (if/then logic based on behavior)

Core Automation Workflows

Lead Capture to Nurture

Trigger: form submission
  > Email 1: welcome (immediate)
  > Email 2: value email (day 1)
  > Check engagement:
    - If opens: continue nurture
    - If not: send re-engagement variant
  > Continue until sales-ready signal
  > Transfer to sales sequence

Abandoned Cart Recovery

Trigger: cart abandoned (1hr)
  > Email 1: reminder + social proof (existing customers skip discount)
  > Wait 24hr
  > Email 2: objection-handling
  > Wait 48hr
  > Email 3: final with incentive
  > Exit on purchase at any stage
  > Tag as "cart abandoner" for retargeting

Post-Purchase Loyalty Loop

Trigger: purchase
  > Confirmation email
  > Check-in after delivery
  > Review request (7d)
    - If review: thank-you + referral ask
    - If no review: gentle reminder
  > Cross-sell (30d)
  > Enter repurchase reminder cycle

Engagement-Based Scoring

Track behavior:
  +1 open
  +3 click
  +5 pricing page visit
  +10 demo/trial request

Score > 20: transfer to sales sequence
No engagement 30d: enter re-engagement sequence

Workflow Best Practices

• Always include exit conditions - purchase, unsubscribe, goal achieved
• Set frequency caps - no more than 1 automated email per day per subscriber (excluding transactional)
• Tag subscribers - entering and exiting workflows for reporting
• Test with seed addresses - before activation
• Review monthly - pause underperformers

Frequency Caps Across Workflows

Open Rates by Industry

Note: Apple Mail Privacy Protection (MPP) inflates open rates by 10-15 percentage points. Report both "all opens" and "non-MPP opens" when possible.

What Determines a "Good" Open Rate

• Above 25%: Excellent -- strong list hygiene and engaged audience
• 20-25%: Good -- performing at or above industry average
• 15-20%: Average -- room for improvement in subject lines or segmentation
• Below 15%: Needs attention -- check deliverability, list quality, sender reputation

---

Click-Through Rates by Industry

CTR Improvement Levers

• Single clear CTA outperforms multiple CTAs by 30-40%
• Personalized CTAs convert 202% better than generic ones
• Button CTAs outperform text links by 28%
• Above-the-fold CTA placement increases clicks by 20-30%

---

Conversion Rates by Email Type

---

Unsubscribe & Bounce Rate Thresholds

Spam Complaint Thresholds by Provider

• Google (Gmail): Must stay below 0.10%; aim for < 0.05%. Google Postmaster Tools is essential.
• Yahoo / AOL: Below 0.08% recommended after Feb 2024 sender requirements.
• Microsoft (Outlook): Less transparent; keep below 0.1%.

When to Worry

• Unsubscribe spike after a specific campaign: review content, frequency, segment targeting
• Gradual unsubscribe increase over months: likely frequency fatigue or list quality decay
• Sudden bounce spike: check for list import issues or ESP deliverability problems

---

Revenue Per Email by Industry

Key Revenue Benchmarks

• Email should drive 25-40% of ecommerce revenue (Klaviyo benchmark)
• Automated flows should generate 40-60% of email revenue from < 5% of total sends
• Average ROI: $36-42 returned per $1 spent on email marketing
• Top performers: $50+ returned per $1 spent

---

Automation Sequence Benchmarks

Welcome Series

Abandoned Cart Series

Post-Purchase Series

Best Send Times by Audience Type

B2B Audiences

B2C / Ecommerce Audiences

Send Time Optimization Notes

• Always send in the recipient's local timezone (most ESPs support this)
• Test your own data -- these benchmarks are starting points, not rules
• Send time optimization (STO) features in Klaviyo, Mailchimp, and others can lift open rates 5-15%
• Automated flows should fire based on trigger timing, not batch send windows

---

Subject Line Performance Data

Length Impact on Open Rates

Elements That Boost Open Rates

Preview Text Optimization

• Preview text is visible in 90%+ of email clients
• Optimal length: 40-90 characters
• Should complement (not repeat) the subject line
• Acts as a "second subject line" -- treat it with equal importance
• If left blank, email clients pull body text (often ugly HTML artifacts)

---

A/B Testing Requirements

Minimum Sample Sizes for Statistical Significance

Practical A/B Testing Guidelines

• Test one variable at a time for clear results
• Run test for minimum 4 hours (subject line) or 7+ days (automation changes)
• Use at least a 10-15% sample before sending winner to remainder
• Priority order for testing: Subject line > Send time > CTA > Content layout > From name
• Document every test -- build an institutional knowledge base

How to Use These Benchmarks

1. Find your industry baseline from the tables above
2. Compare your current metrics to identify gaps and opportunities
3. Set realistic targets -- aim for top quartile, not perfection
4. Prioritize automation revenue -- it consistently outperforms campaigns 5-8x per email
5. Revisit quarterly -- benchmarks shift as privacy changes and consumer behavior evolve
6. Test against your own data -- your audience may deviate significantly from averages

Remember: These are industry averages. A well-segmented list of 5,000 engaged subscribers will outperform a poorly-managed list of 100,000 every time. Quality over quantity.

Email Marketing Best Practices & Industry Standards (2025-2026)

Purpose: Comprehensive deliverability, segmentation, automation, and design reference for email marketing.

---

1. Deliverability

Authentication (Non-Negotiable)

Google/Yahoo Sender Requirements (Feb 2024+, enforced 2025):

• SPF or DKIM required for all senders
• DMARC required for bulk senders (5,000+ emails/day to Gmail)
• One-click unsubscribe header required (List-Unsubscribe-Post)
• Spam complaint rate must stay below 0.3% (target < 0.1%)
• Valid forward and reverse DNS (PTR records)
• TLS encryption for transmission

List Hygiene

• Bounce handling: Remove hard bounces immediately. Soft bounces: retry 3x, then remove.
• Sunset policy: Disengage subscribers who haven't opened/clicked in 90-180 days. Send re-engagement campaign first, then suppress.
• Verification: Run list through verification service (ZeroBounce, NeverBounce, BriteVerify) before importing or after prolonged inactivity.
• Spam traps: Never purchase lists. Pristine spam traps (never-used addresses) are fatal to deliverability.
• Regular pruning: Clean list quarterly. A smaller, engaged list outperforms a large, unengaged one.

Warm-Up Protocol (New Domain/IP)

Send to most engaged subscribers first. Monitor bounce rates (< 2%), spam complaints (< 0.1%), and inbox placement throughout.

Spam Trigger Words to Avoid

Not as impactful as they once were (modern filters use ML, not word lists), but still worth avoiding in subject lines: "Free", "Act now", "Limited time", "Congratulations", "Winner", excessive ALL CAPS, multiple exclamation marks, "Click here", "$$$", "No obligation".

More important: consistent send volume, good engagement metrics, proper authentication, and low complaint rates.

---

2. List Building

Opt-In Best Practices

Recommendation: Double opt-in for EU audiences (GDPR). Single opt-in + verification for US/global audiences focused on growth.

Lead Magnet Strategies That Convert (2025)

GDPR/CAN-SPAM/CCPA Compliance Checklist

• Explicit consent for marketing emails (GDPR: affirmative action, no pre-checked boxes)
• Clear privacy policy linked at point of collection
• Physical mailing address in email footer (CAN-SPAM)
• One-click unsubscribe mechanism (CAN-SPAM + Google/Yahoo requirement)
• Honor unsubscribe within 10 business days (CAN-SPAM) — best practice: instant
• Record of consent (date, time, method, what they consented to) (GDPR)
• Right to erasure process (GDPR)
• Data processing agreement with email service provider (GDPR)

---

3. Segmentation

RFM Segmentation

Engagement-Based Segments

Behavioral Segmentation Triggers

• Page visited (pricing page → sales email, product page → product email)
• Content downloaded (whitepaper topic → related nurture sequence)
• Cart abandoned (abandonment recovery sequence)
• Product purchased (cross-sell, review request, replenishment)
• Feature used/not used (in-app: activation, feature adoption)
• Email engagement pattern (opens-but-never-clicks → different CTA strategy)

---

4. Automation Sequences

Welcome Series (Optimal: 3-5 Emails, 7-14 Days)

Welcome series benchmark: 50-60% open rate, 15-25% click rate (significantly above regular campaigns).

Abandoned Cart (3 Emails)

Total abandoned cart recovery: 10-18% of abandoned carts. Revenue per email from cart abandonment is typically 10-20x regular promotional emails.

Win-Back (4-Email Sunset Flow)

Win-back rate: 5-12% of dormant subscribers typically re-engage.

Post-Purchase (Ecommerce)

B2B Lead Nurture (6-Email Educational Drip)

---

5. Design & Copy

Mobile-First Design

• 60%+ of email opens are on mobile (some audiences 80%+)
• Single-column layout, minimum 14px body text, 22px+ headlines
• CTA buttons: minimum 44x44px tap target, full-width on mobile
• Keep email width 600px for desktop, responsive to 320px for mobile
• Preview in Gmail, Apple Mail, Outlook (the big three) before sending

Subject Line Best Practices

Length: 30-50 characters optimal (6-10 words). Shorter for mobile visibility.

Preview text: 40-90 characters that complement (not repeat) the subject line. This is the second most important factor in open rates after subject line.

CTA Best Practices

• One primary CTA per email (additional secondary CTAs OK but de-emphasized)
• Button text: Action-oriented, specific ("Get My Free Template" > "Click Here" > "Submit")
• Color: High contrast against email background. Consistent with brand but stands out.
• Placement: Above the fold for short emails, repeated for long emails
• Surrounding whitespace: 20px+ padding around CTA button

---

6. Benchmarks by Industry (2025-2026)

Supporting file: references/cold-email.md

Cold and Outbound B2B Email

Cold email is distinct from lifecycle and newsletter email. Different rules apply.

Cold Email Voice and Mindset

• Write like a peer, not a marketer - no ALL CAPS, no "exciting opportunity," no corporate enthusiasm
• Lead with their world, not your product - open with something true about prospect's situation
• Ruthlessly short - 5-9 sentences max. Every sentence must earn its place
• One ask per email - one clear, low-friction action

Subject Lines and Structure

Subject lines: 2-4 words, lowercase (quick question, {company} + {their company}). No clickbait, exclamation marks, or emojis.

Subject: {2-4 words, lowercase}

{Opening: one sentence grounded in their world}

{Body: 1-3 sentences - your value in their terms}

{CTA: one low-friction ask - "worth a quick chat?"}

{Name}
{Title, Company}

Avoid: long intros, feature lists, "I hope this email finds you well," links or attachments in email 1.

CTA Friction Ladder

No calendar links in the first email.

Follow-Up Sequence (3-5 emails)

Cold email rarely converts on email 1. Sequences work. Each follow-up needs a fresh angle - do not just say "following up."

Key rule: After 5 emails with no reply, remove from sequence. Continuing damages deliverability and reputation.

Personalization at Scale

Effective cold email feels personal. For scale, personalize in tiers:

| Tier | Approach | Use Case | |---|---| | Tier 1 (top accounts) | Fully bespoke | Research company, reference something specific | | Tier 2 (mid-tier) | Segment-personalized | Custom first line per industry vertical or role | | Tier 3 (high volume) | Template + merge fields | Company name, job title, industry inserted dynamically |

Technical Hygiene for Cold Email

• Use separate sending domain (e.g., trybrand.com) to protect main domain reputation
• Warm up new domains 3-4 weeks before scaling
• Send plain-text or minimal HTML
• Monitor reply rates (aim 5-15%), bounce rates (under 3%), spam complaints
• Comply with CAN-SPAM, GDPR, CASL - B2B cold email to relevant prospects is permitted with proper opt-out

Output Format

When writing cold email sequences, produce:

1. Full email copy for each step (subject + body)
2. Notes on angle used per email and why
3. Personalization variables to fill per prospect or segment
4. CTA instructions (next step in sales process when they respond)

Save to ./brands/{brand-slug}/channels/email/content/cold-outbound-{campaign-name}-{YYYY-MM-DD}.md

Supporting file: references/email-copywriting.md

Email Copywriting

Write emails that get opened, clicked, and acted upon.

Subject Line Formulas

Subject lines determine open rates. Target 30-50 characters (6-10 words). Test every send.

Proven formulas:

Power words: free, new, exclusive, limited, proven, secret, instant, urgent, breaking, insider, mistake, warning, invitation, last chance.

Spam triggers (use sparingly): guarantee, no obligation, act now, winner, congratulations, risk-free, 100% free, click here, buy now.

Preheader Text

The second subject line - 40-100 characters visible in inbox preview.

• Never leave blank (email clients pull body text instead)
• Complement the subject line, do not repeat it
• Add context, intrigue, or secondary benefit
• Use as one-two punch: subject hooks, preheader sells the open

Body Copy Structure

Inverted pyramid: most important message first, supporting details second, CTA third.

Best practices:

• Short paragraphs (1-3 sentences)
• One idea per paragraph
• Conversational tone matching brand voice
• Use "you" more than "we"
• Write at 8th-grade reading level
• Break up text with subheads, bold key phrases, whitespace

For long-form newsletters:

• Hook with story or surprising stat
• Deliver core insight
• Provide actionable takeaways
• Close with CTA
• Use the PS line (second most-read element after subject line)

Calls to Action

One primary CTA per email. Repeat 2-3 times in different formats:

• Text link
• Button
• PS line

Button best practices:

• Action-oriented, specific
• First-person when possible ("Start my free trial" beats "Sign up")
• Most visually prominent element
• Add urgency or benefit context ("Join 10,000 marketers" above button)

Personalization

Beyond first-name merge tags:

• Dynamic content blocks based on segment
• Product recommendations from purchase history
• Location-based content
• Behavior-triggered messaging
• Anniversary/milestone emails
• Personalized send times

AI-powered options:

• Subject line optimization per recipient
• Predictive send-time optimization
• Dynamic content selection based on engagement patterns

Ethics: Persuasion Without Manipulation

Email marketing runs on psychological techniques - subject line curiosity, urgency, scarcity, FOMO, personalization. These tools convert but can cross into manipulation. This section defines the ethical line.

Ethical Email Practices

Ethical email helps subscribers make decisions aligned with their interests. The subscriber who acts should be glad they did.

Core Principles

• Genuine scarcity - "48 hours left" means 48 hours. Limited spots are actually limited. The offer truly expires.
• Real urgency - Time-sensitive emails reference actual deadlines (trial expiry, cart hold, genuine offer end) - not fabricated pressure.
• Honest subject lines - The email delivers on the subject line promise. "Your account" emails are about the account - not a sales pitch in disguise.
• Clear unsubscribe - One-click unsubscribe, honored within 24 hours. Preference centers over forced opt-outs.
• Transparent senders - Clear "from" name and reply address. No misleading sender names.
• Truthful content - Testimonials are real. Statistics are verifiable. Claims are accurate.

Dark Patterns to Avoid

The Long-Term Case for Ethics

Dark patterns boost metrics short-term and destroy sender reputation long-term.

The subscriber who feels manipulated:

• Marks as spam (damages deliverability for everyone)
• Unsubscribes with frustration
• Leaves negative reviews
• Never opens future emails

The subscriber who feels well-served:

• Opens consistently
• Clicks and converts
• Forwards to friends
• Becomes a referral source

The Ethics Test

Before sending any email, ask:

If the subscriber understood every technique used, would they still feel respected?

If no, rewrite the email.

Abandoned Cart Series

Goal: Recover abandoned carts. Trigger: Cart created, no purchase within 1 hour. Emails: 3 over 72 hours.

Email 1: Gentle Reminder (1 hour)

• Subjects: "You left something behind, [Name]" | "Your cart is waiting for you" | "Did something go wrong?"
• Elements: Cart contents with product images/names/prices, NO discount yet, checkout help offer, trust signals (security badge, return policy, payment options)
• CTA: "Complete your order" (single prominent button)

Email 2: Social Proof + Urgency (24 hours)

• Subjects: "[Product name] is selling fast" | "Other shoppers are eyeing your cart"
• Elements: Cart contents again, 1-2 product reviews, scarcity ("Only [X] left" if true), small incentive (free shipping or 5-10% off), FAQ on top objections

How to Use These Frameworks

1. Select the framework that matches your business model and goal
2. Customize timing based on your sales cycle and audience data
3. Adapt subject lines as starting points, then A/B test variations
4. Implement branching gradually -- start with core sequence, add branches as data comes in
5. Measure against benchmarks in the companion file (benchmarks.md)
6. Iterate quarterly -- review performance, update copy, test new structures

Every email in a sequence should be valuable on its own. Don't create dependencies where missing one email makes the next one confusing.

Modern and Emerging Email Practices

Stay current with email technology and best practices.

AI-Powered Email

Subject Line Optimization

AI tools predict open rates and suggest variants:

• Phrasee, Jasper, ESP-native AI
• Test multiple AI-generated variants against human-written control

Send Time Optimization

Per-recipient optimal send time based on historical open patterns:

• Available in Klaviyo, ActiveCampaign, Mailchimp
• Improves open rates 10-20% on average

Dynamic Content

AI-selected content blocks personalized per recipient:

• Product recommendations based on purchase history and browsing
• Content blocks based on engagement patterns
• Offer selection based on predicted preferences

Predictive Analytics

Inform segmentation and messaging:

• Churn prediction scores
• Purchase likelihood scoring
• Lifetime value forecasting

Interactive Emails (AMP for Email)

In-email actions without leaving inbox:

• Surveys, polls, carousels
• Add-to-cart, appointment booking
• Accordion menus, form submission

Support: Gmail, Yahoo, Mail.ru Requirement: HTML fallback for unsupported clients

Use cases:

• Product browsing
• Feedback collection
• Event RSVP
• Form submission

Dark Mode Optimization

• Test emails in both light and dark mode
• Use transparent PNGs for logos
• Avoid images with white backgrounds (harsh contrast)
• Use @media (prefers-color-scheme: dark) CSS when supported
• Ensure text readable in both modes
• Test across: Apple Mail, Gmail, Outlook

Accessibility

Semantic HTML

• Proper heading hierarchy
• Table roles for layout tables
• Lang attribute on email element

Visual Accessibility

• Alt text on every image (decorative images: alt="")
• Minimum 14px font size
• Line height 1.5x
• Color contrast WCAG AA: 4.5:1 for text

Layout Accessibility

• Single-column layouts for screen reader compatibility
• Bulletproof buttons (HTML/CSS, not image-based)
• Meaningful link text (not "click here")

Testing

Test with:

• Screen readers (NVDA, VoiceOver)
• Accessibility checkers (Litmus Accessibility Checker)

Privacy-First Email

First-Party Data Strategy

Collect data directly through:

• Subscriber interactions
• Preference centers
• Zero-party surveys

Reduce Open-Rate Reliance

Apple MPP impact on open tracking:

• Shift KPIs to clicks, conversions, revenue
• Open rates increasingly unreliable for engagement signals

Transparent Data Usage

Tell subscribers:

• What you track
• Why you track it
• How they can control it

Preference Centers

Let subscribers control:

• Frequency
• Topics/content types
• Data sharing preferences

Supporting file: references/newsletter-strategy.md

Newsletter Strategy

Build a newsletter that delivers consistent value and drives business outcomes.

Newsletter Types

Content Framework

Every issue follows this structure:

1. Hook - subject line + preheader + opening line
2. Value section - education, insights, resources (80%)
3. Brand section - product updates, community (20%)
4. CTA - one primary action
5. Footer - preferences, social, forward-to-friend

The 80/20 rule: 80% value, 20% promotion.

Frequency and Send Time

Best send days:

• Tuesday-Thursday for B2B
• Weekends for B2C lifestyle

Best send times:

• 9-11am local for B2B
• 7-9pm for B2C

Key insight: Consistency matters more than frequency. Weekly is the sweet spot for most brands.

Segmented Newsletters

Do not send the same newsletter to everyone. Segment by:

• Engagement level (active vs passive)
• Purchase history
• Interest tags (click behavior)
• Lifecycle stage
• Geography

Personalize content blocks, recommendations, and CTAs per segment. Basic segmentation improves click rates 20-40%.

Growth Tactics

• Lead magnets - checklists, templates, guides, calculators
• Website opt-ins - exit intent popups, scroll-triggered slide-ins, inline forms
• Content upgrades - bonus content specific to page (5-15% conversion vs 1-3% generic)
• Social promotion - bio links, posts, lead gen ads
• Partnerships - cross-promotion with complementary brands
• Events - webinars, workshops, challenges (registration = opt-in with consent)
• Referrals - incentivize subscribers to share (SparkLoop, ReferralHero)

Supporting file: references/output-contract.md

Output Contract

Define what email deliverables look like and where they save.

Deliverable Types

Path Resolution

Campaign mode (working within named campaign):

./brands/{brand-slug}/campaigns/{type}-{campaign-slug}/channels/email/content/

Read campaign strategy at: ./brands/{brand-slug}/campaigns/{type}-{campaign-slug}/strategy.md

Standalone mode (evergreen or independent work):

./brands/{brand-slug}/channels/email/content/

Legacy fallback (old directory structure):

./brands/{brand-slug}/content/email/

Suggest migration to new structure.

If unsure which mode, ask: "Is this part of a specific campaign, or standalone work?"

Sequence Map Format

For email sequences, include a sequence map table:

Individual Email Format

Each email in deliverable includes:

Email Type: [welcome/nurture/sales/etc]
Subject Line: [Subject] (A/B variant: [Variant] if applicable)
Preview Text: [Preheader]
Body Copy: [Complete email ready for ESP]
CTA: [Primary action] - [link placeholder]
Sequence Position: [Where this fits in flow]

Performance Reports

Monthly performance reports save to:

./brands/{brand-slug}/channels/email/performance/monthly-report-{YYYY-MM}.md

Include: key metrics vs benchmarks, test results, optimization recommendations.

File Saved Confirmation

Every deliverable ends with:

File saved to: [resolved path]/[filename]

• Elements: Cart contents, strongest incentive (10-15% off or free shipping), deadline on incentive (48hr), loss aversion ("We'll release reserved items"), one-click checkout
• CTA: "Complete your order and save [X]%"

Branching Logic

• Purchases after any email --> stop sequence; enter post-purchase flow
• Clicks Email 2 but no purchase --> trigger Email 3 sooner (48hr)
• Cart value above $150 --> higher discount or personal outreach
• Repeat customer --> skip discount, use loyalty language
• No action after Email 3 --> wait 7 days, move to re-engagement segment

---

• Elements: Clear "We'll stop emailing on [date]" statement, single CTA to stay, no-guilt tone, brief reminder of what they'll miss. No engagement = suppress from all marketing sends.
• CTA: "Keep me subscribed" (single unmissable button)

Branching Logic

• Engages at any point --> stop sunset, return to active segment
• Opens but no clicks --> extend by one email before purging
• Clicks preference center --> move to selected frequency/topics
• No engagement after Email 4 --> suppress (do NOT delete; keep for exclusion audiences and compliance)

Newsletter Framework

Goal: Consistent engagement, value delivery, traffic driving. Frequency: Weekly/biweekly/monthly.

Recommended Structure

Best Practices

• Consistency: Same day, same time, every send -- train your audience
• From name: "[Name] from [Brand]" outperforms "[Brand] Newsletter"
• Mobile-first: 60-70% of opens on mobile
• One primary CTA per section -- don't overwhelm with choices
• Preview text: Always customize -- never let it auto-generate
• Track clicks by section -- double down on what resonates

Frequency by Audience

---

Subject Line Formula Quick Reference

Curiosity: "The [adjective] reason [audience] are [doing X]" | "I was wrong about [belief]" | "This [small change] led to [big result]"

Value: "How to [result] in [timeframe]" | "[Number] ways to [solve problem] without [pain]" | "The [audience]'s guide to [topic]"

Urgency: "[X] hours left: [offer]" | "Last chance to [benefit]" | "Ends tonight: [offer]"

Personalization: "[Name], your [element] is ready" | "Based on your [action], we thought..." | "Recommended for you: [item]"

Social Proof: "[Number]+ [audience] already [doing X]" | "Why [company] switched to [product]" | "Rated [X] stars by [number] customers"

Questions: "Are you making this [topic] mistake?" | "What would you do with [extra result]?" | "Is [common approach] hurting your [metric]?"

How to Use These Frameworks

1. Select the framework that matches your business model and goal
2. Customize timing based on your sales cycle and audience data
3. Adapt subject lines as starting points, then A/B test variations
4. Implement branching gradually -- start with core sequence, add branches as data comes in
5. Measure against benchmarks in the companion file (benchmarks.md)
6. Iterate quarterly -- review performance, update copy, test new structures

Every email in a sequence should be valuable on its own. Don't create dependencies where missing one email makes the next one confusing.

Quick-Reference Sequence Tables (from SKILL.md)

The tables below provide compact email-by-email timing for two high-impact sequences. Use them alongside the detailed frameworks above.

Welcome Sequence Quick Map (3-7 emails, days 0-14)

Average 50-80% open rate on email 1. Purpose: set expectations, deliver promised value, introduce the brand, guide first action.

Abandoned Cart Quick Map (3-4 emails, 1-72 hours)

Recovers 5-15% of abandoned carts on average. Timing is critical.

Shared Skill Patterns

These patterns are referenced by all marketing specialist skills. Read them as part of your operating instructions.

Starting Context Router

Choose the starting mode before doing the work. Brand workspace context is preferred, but do not block progress if the user provides a real codebase or live URL.

Context A — Blank Page / Strategy Work

Use when the user needs strategy, planning, or a fresh roadmap. Read brand and SOSTAC context first when available, then align recommendations to audience, objections, and business goals.

Context B — Existing Local Codebase / Implementation Work

Use when the user wants changes made or specified in an existing repository, site, product, or app. Before proposing changes, deeply research the codebase: inspect the stack, architecture, relevant files, dependencies, and existing patterns. Match existing conventions before changing anything.

Context C — Live Website URL Audit

Use when the user provides a public URL for review. Audit the live experience first. If brand files are missing, use the live page and visible structure as the working source of truth.

Pre-Flight: Read Strategic Context

Before any specialist work, read these files in order when available:

1. ./brands/{brand-slug}/brand-context.md — brand identity, audience, USP
2. ./brands/{brand-slug}/product-marketing-context.md — deep positioning, customer language, objections
3. ./brands/{brand-slug}/sostac/03-strategy.md — target segments, positioning
4. ./brands/{brand-slug}/sostac/04-tactics.md — channel plan, priorities

If brand files are missing but a codebase or live URL is available, continue with that as the working source of truth rather than blocking progress.

agent-browser Setup

Before running browser-based research, check if agent-browser is available (agent-browser --version). If the command is not found, install it:

# Install the agent-browser skill (recommended)
npx skills add https://github.com/vercel-labs/agent-browser --skill agent-browser

# Or install the CLI directly
npm install -g agent-browser && npx playwright install chromium

If installation fails, use WebFetch and WebSearch tools as alternatives for all research tasks.

Email Strategy Framework

Define email's role before writing a single message.

Email Categories

Channel Role Definition

Before building sequences, define email's role in the marketing mix:

• Primary acquisition channel - email captures and converts leads from other channels
• Retention engine - email nurtures existing customers toward repeat purchase and loyalty
• Revenue driver - email generates direct revenue through promotions and product recommendations
• Relationship builder - email delivers value (content, education, community) that deepens brand affinity

SOSTAC Alignment

Map to the SOSTAC objectives:

• If primary objective is acquisition - prioritize welcome and nurture sequences
• If primary objective is retention - prioritize post-purchase and re-engagement

Sequence Type Overview

Framework Lookup

For complete email-by-email templates with timing and copy:

1. Open ./references/frameworks-index.csv
2. Match sequence_type, best_for, or tags to user goal
3. Read only the matched framework file
4. Never load all frameworks at once
