# Email Sequence Design

**Category:** Marketing
**Tags:** email sequences, drip campaigns, nurture flows, onboarding emails, lifecycle marketing, automation

## Overview

Email Sequence Design creates complete, ready-to-implement email automation flows. Every output includes subject lines, preview text, full body copy, CTAs, send timing, and exit conditions. The goal is sequences that nurture relationships and drive specific conversion actions -- not just "stay top of mind" email noise.

This skill writes the sequences. For email HTML templates and rendering infrastructure, use email-template-builder. For tracking email performance, use analytics-tracking.

## Sequence Types

| Type | Trigger | Goal | Typical Length |
|------|---------|------|---------------|
| Welcome/Onboarding | New signup | Activate user, show core value | 5-7 emails over 14 days |
| Trial Expiration | Trial nearing end | Convert to paid | 4-5 emails over 7 days |
| Lead Nurture | Content download, webinar | Qualify and convert | 6-8 emails over 30 days |
| Re-engagement | Inactive 30+ days | Bring back or clean list | 3-4 emails over 14 days |
| Post-Purchase | Subscription start | Reduce churn, expand | 4-6 emails over 30 days |
| Event-Based | Specific user action | Drive next action | 2-3 emails over 7 days |
| Sales (Warm) | MQL or PQL signal | Book meeting or start trial | 4-5 emails over 14 days |

## Design Process

### Step 1: Define Sequence Architecture

Before writing any email, define the architecture:

```
Sequence Name:     [Name]
Trigger:           [What starts the sequence]
Primary Goal:      [Single conversion action]
Secondary Goals:   [Relationship building, data collection]
Length:            [Number of emails]
Duration:          [Total time span]
Exit Conditions:   [When they leave the sequence]
Suppression:       [Other sequences to suppress while active]
```

### Step 2: Map the Emotional Journey

Each email serves a purpose in a progression:

| Email | Emotional State | Purpose | Key Message |
|-------|----------------|---------|-------------|
| 1 | Curious, uncertain | Welcome, set expectations | "Here's what to expect" |
| 2 | Exploring, evaluating | Demonstrate core value | "Here's the one thing to try first" |
| 3 | Engaged or dropping off | Social proof | "Here's how others succeeded" |
| 4 | Considering commitment | Remove objections | "Common concerns addressed" |
| 5 | Ready to decide | Create urgency | "Your trial ends in X days" |

### Step 3: Write Each Email

For every email in the sequence, deliver:

```
Email [#]: [Name/Purpose]
Send:     [Timing from trigger or previous email]
Segment:  [Conditions -- who receives this variant]

Subject:  [Subject line - under 50 characters]
Preview:  [Preview text - 80-120 characters, complements subject]

Body:
[Complete copy -- not an outline, not bullets, the actual words]

CTA:      [Button text] → [Destination URL]
P.S.:     [Optional -- works for urgency or human touch]
```

### Step 4: Define Branching Logic

Not everyone follows the same path. Define branches:

```
After Email 2:
  IF user activated core feature → Skip to Email 4 (post-activation)
  IF user has not logged in → Send Email 2B (re-engagement variant)
  IF user unsubscribed → Exit sequence

After Email 4:
  IF user converted → Exit sequence, enter post-purchase sequence
  IF user visited pricing 2+ times → Send Email 4B (pricing objection handler)
  ELSE → Continue to Email 5
```

## Sequence Blueprints

### Blueprint: SaaS Welcome/Onboarding (7 emails, 14 days)

| Email | Day | Subject | Purpose |
|-------|-----|---------|---------|
| 1 | 0 (immediate) | Welcome to [Product] -- start here | Set expectations, one CTA to activate |
| 2 | 1 | The one feature that changes everything | Drive to core value action |
| 3 | 3 | How [Company] got [Result] in [Timeframe] | Social proof, case study |
| 4 | 5 | Quick question | Check engagement, offer help |
| 5 | 7 | 3 things you might have missed | Feature discovery, breadth |
| 6 | 10 | Your trial is halfway done | Progress report, urgency |
| 7 | 13 | Last day of your trial | Convert or lose access |

**Exit conditions:** User converts to paid at any point, user unsubscribes, user explicitly requests removal.

**Branching:**
- After Email 2: If user completed core action, skip Email 3, go to Email 4
- After Email 4: If user has not logged in for 5+ days, switch to re-engagement variant
- After Email 6: If user visited pricing page, send pricing-focused Email 7 variant

### Blueprint: Lead Nurture (6 emails, 30 days)

| Email | Day | Subject | Purpose |
|-------|-----|---------|---------|
| 1 | 0 | Your [resource name] is ready | Deliver promised content |
| 2 | 3 | The mistake most [role] make with [topic] | Educational, establish authority |
| 3 | 7 | [Company] went from [problem] to [result] | Case study, social proof |
| 4 | 14 | The [topic] framework we use internally | Exclusive value, reciprocity |
| 5 | 21 | Quick question about [their challenge] | Personal, segmentation |
| 6 | 28 | See if [Product] is right for you | Soft CTA, demo or trial |

**Exit conditions:** Books demo, starts trial, unsubscribes, or completes sequence.

### Blueprint: Re-engagement (4 emails, 14 days)

| Email | Day | Subject | Purpose |
|-------|-----|---------|---------|
| 1 | 0 | We noticed you've been away | Acknowledge absence, show value |
| 2 | 3 | Here's what you missed | Product updates, new features |
| 3 | 7 | [Exclusive offer or incentive] | Incentivize return |
| 4 | 14 | Should we stop emailing you? | Clean list, last chance |

**Critical rule:** If no engagement after Email 4, remove from active email list. Sending to unengaged contacts damages sender reputation.

### Blueprint: Trial Expiration (5 emails, 7 days)

| Email | Day Before Expiry | Subject | Purpose |
|-------|-------------------|---------|---------|
| 1 | 7 | Your trial ends in one week | Awareness, usage summary |
| 2 | 3 | Here's what you'll lose access to | Loss aversion, feature list |
| 3 | 1 | Tomorrow is your last day | Urgency, simple CTA |
| 4 | 0 | Your trial just ended | Conversion, offer extension option |
| 5 | +3 | We saved your data for 30 days | Last chance, data retention |

## Subject Line Framework

### Formulas That Work

| Formula | Example | Why It Works |
|---------|---------|-------------|
| How [company] [achieved result] | "How Stripe reduced churn 23%" | Specific, curiosity, social proof |
| The [number] [thing] [audience] [needs] | "The 3 metrics every PM tracks" | Specific, relevant, scannable |
| Quick question about [topic] | "Quick question about your trial" | Personal, non-threatening |
| [Name], [action-oriented statement] | "Sarah, your dashboard is ready" | Personal, action-oriented |
| Your [asset] is [status] | "Your free trial ends tomorrow" | Ownership, urgency |

### Subject Line Rules

1. Under 50 characters (mobile truncation happens at 35-45)
2. No ALL CAPS words
3. No excessive punctuation (!!!)
4. No spam trigger words in subject: free, guarantee, limited time, act now
5. Preview text must complement, not repeat, the subject
6. A/B test subject lines on every sequence (minimum 3 variants per email)

## Timing & Cadence

### Optimal Send Times (B2B SaaS)

| Day | Time Window | Notes |
|-----|-------------|-------|
| Tuesday | 9-11 AM recipient's timezone | Highest open rates |
| Wednesday | 9-11 AM | Second best |
| Thursday | 9-11 AM | Good for follow-ups |
| Monday | 10 AM-12 PM | After inbox clearing |
| Friday | Avoid for important emails | Low engagement |
| Weekend | Avoid for B2B | Exception: consumer products |

### Sequence Spacing Rules

- Welcome email: Immediate (within 5 minutes of trigger)
- Onboarding emails: Every 1-3 days (maintain momentum)
- Nurture emails: Every 3-7 days (avoid fatigue)
- Re-engagement: Every 3-5 days (test urgency vs respect)
- Trial expiration: Accelerating cadence (7 days, 3 days, 1 day, 0, +3)
