- **Sequence design** — Planning multi-touch email campaigns
- **Email copywriting** — Writing individual emails within sequences
- **Branching logic** — Creating behavior-based email flows
- **Optimization** — Improving existing sequence performance
- **A/B testing** — Designing experiments to improve metrics

## Sequence Types and Frameworks

### Welcome Sequence (5-7 emails, 14-21 days)

| Email | Timing | Purpose | CTA |
|-------|--------|---------|-----|
| 1 | Immediate | Deliver promise, set expectations | Confirm subscription |
| 2 | Day 2 | Introduce brand story | Read content |
| 3 | Day 4 | Deliver value (best content) | Engage |
| 4 | Day 7 | Social proof + quick win | Try free resource |
| 5 | Day 10 | Address common objection | Soft product intro |
| 6 | Day 14 | Customer success story | Explore product |
| 7 | Day 21 | Direct offer + scarcity | Purchase/demo |

### Lead Nurture Sequence (8-12 emails, 30-60 days)

| Stage | Emails | Content Focus | Goal |
|-------|--------|---------------|------|
| **Awareness** | 1-3 | Educational, problem-focused | Build trust |
| **Consideration** | 4-7 | Solution-focused, comparisons | Establish fit |
| **Decision** | 8-12 | Social proof, offers, urgency | Drive action |

### Re-Engagement Sequence (3-5 emails, 7-14 days)

| Email | Subject Style | Content | CTA |
|-------|--------------|---------|-----|
| 1 | "We miss you" | Value reminder | Re-engage |
| 2 | "What happened?" | Survey/feedback | Tell us why |
| 3 | "Last chance" | Exclusive offer | Act now |
| 4 | "Goodbye" | Opt-out warning | Stay or go |

### Sales Follow-Up Sequence (5-7 emails, 10-14 days)

| Email | Timing | Purpose |
|-------|--------|---------|
| 1 | Same day | Thank you + recap |
| 2 | Day 2 | Value add resource |
| 3 | Day 5 | Social proof case study |
| 4 | Day 7 | Address objection |
| 5 | Day 10 | Create urgency |
| 6 | Day 14 | Breakup email |

### Abandoned Cart Sequence (3-4 emails, 72 hours)

| Email | Timing | Subject | Content |
|-------|--------|---------|---------|
| 1 | 1 hour | "Forgot something?" | Cart reminder + image |
| 2 | 24 hours | "Still thinking?" | Address objections |
| 3 | 48 hours | "X% off your cart" | Incentive |
| 4 | 72 hours | "Last chance" | Expiring offer |

## Branching Logic Framework

### Behavior-Based Triggers

| Trigger | Action |
|---------|--------|
| Opens but doesn't click | Send follow-up with different angle |
| Clicks link | Tag interest, send related content |
| Visits pricing page | Trigger sales sequence |
| No open after 3 emails | Change send time/day |

### Engagement Scoring

```
Email Opened       = +1 point
Link Clicked       = +3 points
Reply              = +5 points
Page Visit         = +2 points
Form Submission    = +10 points
```

**Routing:** 0-5 pts → nurture | 6-15 pts → accelerate | 16+ pts → sales alert

## Email Copywriting Framework

### Subject Line Formulas

| Formula | Example | Best For |
|---------|---------|----------|
| **Question** | "Struggling with [problem]?" | Awareness |
| **How-to** | "How to [outcome] in [time]" | Educational |
| **Number** | "5 ways to [benefit]" | Value-packed |
| **Curiosity** | "The [adjective] truth about [topic]" | Engagement |
| **Personal** | "[Name], quick question" | Reply-seeking |
| **Urgency** | "[X hours] left: [offer]" | Action |

### Email Body Structure (AIDA)

```
ATTENTION  → Hook with subject + first line
INTEREST   → Build relevance to their situation  
DESIRE     → Show the transformation/benefit
ACTION     → Clear, single CTA
```

### CTA Best Practices

| Strong CTAs | Weak CTAs |
|-------------|-----------|
| "Start your free trial" | "Click here" |
| "Download the guide" | "Learn more" |
| "Book your demo" | "Submit" |

## Timing and Cadence

### Send Time Optimization

| Audience | Best Days | Best Times |
|----------|-----------|------------|
| **B2B** | Tue, Wed, Thu | 9-11 AM, 1-3 PM |
| **B2C** | Tue, Thu, Sat | 10 AM, 8 PM |

### Frequency Guidelines

| Stage | Frequency |
|-------|-----------|
| New subscriber | Daily for 3, then every 2-3 days |
| Engaged lead | 2-3x per week |
| Nurturing | Weekly |
| Customer | Bi-weekly to monthly |

## A/B Testing Framework

### Test Priority (highest to lowest impact)

1. Subject lines
2. Send time/day
3. CTA text and button color
4. Email length
5. Personalization

### Test Protocol

- **Sample size:** Minimum 1,000 per variant
- **Duration:** Until statistical significance (3-7 days)
- **Rule:** One variable at a time

| **Open Rate** | <15% | 15-25% | 25-35% | >35% |
