Process

Step 1: Define the Campaign

## Campaign Brief

- **Campaign name**: [Descriptive name]
- **Type**: [Newsletter / Promotion / Welcome / Onboarding / Re-engagement / Transactional]
- **Goal**: [What action should recipients take?]
- **Audience**: [Segment — who receives this?]
- **Send frequency**: [One-time / Daily / Weekly / Triggered]
- **Success metric**: [Open rate / Click rate / Conversion rate / Revenue]
- **Target numbers**: [Specific goal: e.g., 25% open rate, 3% click rate]
- **Sender name**: [Who is this from?]
- **Landing page**: [Where does the primary CTA link?]

Step 2: Subject Line Optimization

Generate and evaluate subject line variants:

## Subject Line Framework

### Variants by Approach

**Curiosity** (what happens next?)
- The one thing your [audience] is missing about [topic]
- I didn't expect this to work (but it did)
- [Number] [things] your competitors already know

**Urgency/Scarcity** (time-sensitive)
- 24 hours left: [offer/benefit]
- [Deadline] is almost here — here's what to do
- Last chance to [action]

**Benefit-Driven** (what's in it for them?)
- How to [achieve outcome] in [timeframe]
- The simple way to [solve problem]
- Get [benefit] without [common obstacle]

**Personal/Social Proof** (human connection)
- How [person/company] achieved [result]
- What I learned after [experience]
- [Number] people already [action] — here's why

**Direct** (for B2B / transactional)
- [Action required]: [what/why]
- Your [thing] is ready
- Update: [what changed]

### Subject Line Checklist
- [ ] Under 50 characters (mobile displays ~40-50)
- [ ] First 20 characters contain the hook (preview text matters)
- [ ] No misleading claims (trust > clicks)
- [ ] No ALL CAPS or excessive punctuation (!!!)
- [ ] Personalization where appropriate (first name, company)
- [ ] Aligned with email content (no bait-and-switch)
- [ ] Preview text complements the subject line (don't repeat)

Step 3: A/B Test Design

## A/B Test Plan

### Test: Subject Line Optimization
- **Variable**: Subject line wording
- **Variants**:
  - A (Control): [Original subject line]
  - B (Challenger): [Modified subject line]
- **Split**: 50/50 of test segment (minimum 1,000 per variant)
- **Duration**: 24 hours (most opens occur in first 4-8 hours)
- **Primary metric**: Open rate
- **Secondary metric**: Click rate (are we attracting the right opens?)

### Test: CTA Design
- **Variable**: Button text and placement
- **Variants**:
  - A: "Learn More" button below main content
  - B: "Get Started Now" button above fold + below content
- **Split**: 50/50
- **Primary metric**: Click-through rate
- **Secondary metric**: Conversion rate on landing page

### Test: Send Time
- **Variable**: Day and time of send
- **Variants**:
  - A: Tuesday 10:00 AM
  - B: Thursday 2:00 PM
- **Split**: 25/25 (hold 50% for the winner rollout)
- **Primary metric**: Open rate + click rate combined
- **Duration**: Test both sends, compare 48-hour results

### A/B Test Rules
1. **Test one variable at a time** — multiple changes = unclear results
  — don't call a test after 100 opens
  — ensure both variants see similar audience quality
  — results, hypotheses, and learnings for future tests
  — don't leave performance on the table


 Need at least 1,000 opens per variant for reliable results
 A 5-10% difference in open rates is typically meaningful
 Use a chi-squared test or online calculator for formal significance testing

Step 4: Email Template Creation

<!-- Newsletter Template -->
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>{{subject}}</title>
</head>
<body style="margin:0;padding:0;background-color:#f4f4f4;">
  <table role="presentation" width="100%" cellpadding="0" cellspacing="0" style="background-color:#f4f4f4;padding:20px 0;">
    <tr>
      <td align="center">
        <table role="presentation" width="600" cellpadding="0" cellspacing="0" style="background-color:#ffffff;border-radius:8px;overflow:hidden;">

          <!-- Header / Logo -->
          
            
              
                {{brand_name}}
              
            
          

          
          
            
              
                {{headline}}
              
              
                {{intro_paragraph}}
              
              
              
                
                  
                    
                      {{cta_text}}
                    
                  
                
              
            
          

          
          
            
              
                {{section_title}}
              
              
                {{section_content}}
              
            
          

          
          
            
              
                {{company_name}} · {{company_address}}
              
              
                Unsubscribe ·
                Email preferences
              
            
          

        
      
    
  

Template best practices:

• Use tables for layout (not div/CSS grid — email clients vary wildly)
• Inline all styles (most clients strip <style> blocks)
• Maximum width: 600px (mobile-friendly)
• Alt text on all images (many clients block images by default)
• Always include unsubscribe link (legal requirement: CAN-SPAM, GDPR)
• Test in multiple clients before sending (Gmail, Outlook, Apple Mail, mobile)

Step 5: Drip Sequence Design

## Welcome Sequence (5 emails)

**Trigger**: New subscriber / signup

**Email 1 - Welcome (Immediate)**
- Subject: Welcome to {{brand}} — here's what's next
- Content: Thank you + deliver lead magnet if promised + set expectations (what they'll receive, how often)
- CTA: Follow on social / join community

**Email 2 - Value (Day 2)**
- Subject: The [thing] most [audience] get wrong
- Content: Quick win or key insight (deliver value before asking)
- CTA: Read related content / try a feature

**Email 3 - Social Proof (Day 4)**
- Subject: How [person/company] [achieved result]
- Content: Case study or testimonial showing transformation
- CTA: See more results / start free trial

**Email 4 - Objection Handling (Day 7)**
- Subject: "I'm not sure if this works for [situation]"
- Content: Address top 2-3 objections directly with evidence
- CTA: Book a call / start trial

**Email 5 - Offer (Day 10)**
- Subject: Ready to [achieve outcome]? Let's do this.
- Content: Clear offer with value stack + deadline or urgency element
- CTA: Buy / upgrade / book

## Re-engagement Sequence (3 emails)

**Trigger**: No opens in 60 days

**Email 1 - Check In (Day 1)**
- Subject: We miss you / Are we still a fit?
- Content: Gentle check-in, ask for feedback, offer help
- CTA: Update preferences / reply with feedback

**Email 2 - Best Of (Day 7)**
- Subject: Here's what you missed
- Content: Top 3 best-performing content pieces from the period they missed
- CTA: Read the top post / re-engage

**Email 3 - Last Chance (Day 14)**
- Subject: Last call — should we update your preferences?
 Content: Honest — if this isn't useful, no hard feelings. Update or unsubscribe.
 CTA: Update preferences / unsubscribe

Step 6: Performance Tracking

## Campaign Performance Report

**Campaign**: [Name]
**Date**: [Send date]
**Segment**: [Who received it]

### Core Metrics
| Metric | Result | Benchmark | Status |
|--------|--------|-----------|--------|
| Delivery rate | [%] | >98% | ✅/⚠️ |
| Open rate | [%] | 20-30% (varies by industry) | ✅/⚠️ |
| Click-to-open rate | [%] | 10-20% | ✅/⚠️ |
| Click-through rate | [%] | 2-5% | ✅/⚠️ |
| Conversion rate | [%] | 1-3% | ✅/⚠️ |
| Unsubscribe rate | [%] | <0.5% | ✅/⚠️ |
| Bounce rate | [%] | <2% | ✅/⚠️ |

### What Worked
- [Insight 1 with data]
- [Insight 2 with data]

### What to Improve
- [Issue 1 with hypothesis]
- [Issue 2 with hypothesis]

### Next Actions
1. [Specific change to test next send]
2. [Segment to try or avoid]
3. [Subject line pattern to iterate on]

Error Handling

• Low open rates: Check sender reputation, subject line clarity, and send time; test subject lines with a small segment first
• High unsubscribe rates: Review frequency, content relevance, and expectations set at signup; segment more precisely
• Poor click-through rates: Improve CTA visibility, reduce email length, clarify the value of clicking
• High bounce rates: Clean the list — remove hard bounces, validate email addresses before adding
• Spam complaints: Check content for spam triggers (ALL CAPS, excessive links, misleading subject); review authentication (SPF, DKIM, DMARC)

Common Pitfalls

• ❌ Buying email lists — always grow organically; purchased lists damage sender reputation
• ❌ Image-only emails — many clients block images; always have text fallbacks
• ❌ One-size-fits-all messaging — segment by engagement, interest, and lifecycle stage
• ❌ Ignoring mobile — 60%+ of emails are opened on mobile; test mobile rendering
• ❌ No unsubscribe link — legally required and builds trust; make it easy, not hidden
• ❌ Testing in only one email client — Outlook rendersvery differently than Gmail

Cline Workflow Notes

1. Install location: Copy this skill directory to .cline/skills/email-campaigns/ (project-level) or ~/.cline/skills/email-campaigns/ (global)
2. Always include unsubscribe: Never create an email template without an unsubscribe mechanism
3. Test before sending: Send a test email to yourself and check rendering across clients
4. Subject lines are half the battle: Spend disproportionate time on subject lines — they determine if anything else matters
5. One CTA per email: Multiple competing CTAs dilute click-through rates; pick one primary action
6. Track everything: Every campaign should have measurable goals tracked from send to conversion
7. Respect the inbox: Email is a privilege, not a right — provide value or lose the subscriber
