Sequence Best Practices
Sequence Structure
Standard 5-Step Sequence
| Step | Day | Purpose | Email Type |
|---|---|---|---|
| 1 | 0 | Initial outreach | Problem + value prop |
| 2 | 3 | Social proof | Case study / results |
| 3 | 7 | Alternative angle | Different value prop |
| 4 | 10 | Soft breakup | "If not a fit..." |
| 5 | 14 | Breakup | Last attempt, value-add |
Extended 7-Step Sequence
| Step | Day | Purpose | Email Type |
|---|---|---|---|
| 1 | 0 | Initial outreach | Problem + value prop |
| 2 | 2 | Quick follow-up | Bump + new angle |
| 3 | 5 | Social proof | Case study |
| 4 | 8 | Value-add | Free resource |
| 5 | 12 | Alternative angle | Different ICP pain |
| 6 | 16 | Soft breakup | Check-in |
| 7 | 21 | Breakup | Final attempt |
Timing Guidelines
Optimal Delays
| Between Emails | Recommended | Reasoning |
|---|---|---|
| Email 1 -> 2 | 2-3 days | Stay top of mind |
| Email 2 -> 3 | 3-4 days | Let social proof sink in |
| Email 3 -> 4 | 3-4 days | Give time to consider |
| Email 4 -> 5 | 4-5 days | Breakup needs space |
| After breakup | 30+ days | Cool-off period |
Send Time Optimization
Best Days: Tuesday, Wednesday, Thursday
Best Times:
- 8-10am recipient local time (start of day)
- 2-4pm recipient local time (post-lunch)
Worst Days: Monday morning, Friday afternoon
Worst Times: After 6pm, before 7am
Email Copy Guidelines
Length Guidelines
| Email Type | Word Count | Lines | Reason |
|---|---|---|---|
| Cold outreach | 50-100 | 5-8 | Scannable |
| Follow-up | 30-60 | 3-5 | Quick bump |
| Case study | 100-150 | 8-12 | Tell story |
| Breakup | 40-80 | 4-6 | Clear finale |
Structure Template
[Personalized opening - 1 line]
[Problem statement or insight - 2-3 lines]
[Brief value proposition - 1-2 lines]
[CTA - 1 line]
[Signature]
Subject Line Best Practices
| Do | Don't |
|---|---|
| Keep 3-7 words | Write novel-length subjects |
| Use {{first_name}} or {{company}} | Over-personalize ("Saw you on LinkedIn...") |
| Create curiosity | Mislead with clickbait |
| Be specific when possible | Use generic templates |
| Test lowercase | Use ALL CAPS |
Examples:
- Good: "{{first_name}}, quick question"
- Good: "idea for {{company}}'s Q2"
- Bad: "RE: Our meeting" (fake reply)
- Bad: "FREE TRIAL INSIDE!!!" (spam trigger)
CTA Best Practices
| CTA Type | Example | When to Use |
|---|---|---|
| Soft | "Thoughts?" | Early in sequence |
| Medium | "Worth a quick chat?" | Middle of sequence |
| Direct | "15 min this week?" | After engagement signals |
| Breakup | "Should I close the loop?" | Final email |
One CTA Per Email: Never give multiple options.
Personalization Strategy
Personalization Tokens
| Token | Example | Priority |
|---|---|---|
| {{first_name}} | "Hey Sarah," | Required |
| {{company}} | "saw {{company}}'s recent..." | Recommended |
| {{title}} | "As a {{title}}, you..." | If relevant |
| {{industry}} | "In {{industry}}, we see..." | For segmented |
Custom Personalization
| Level | Effort | Impact |
|---|---|---|
| Basic | Low | {{first_name}}, {{company}} |
| Medium | Medium | + recent company news, role-specific |
| High | High | + mutual connections, specific insight |
Rule: Personalize opening line at minimum. Rest can be templated.
Avoiding Spam Triggers
Words to Avoid

Technical Best Practices
| Practice | Reason |
|---|---|
| No images in cold emails | Trigger spam filters |
| Max 1 link per email | Multiple links = spam |
| No HTML formatting | Plain text performs better |
| Short sentences | Looks more personal |
| No attachments | Major spam trigger |
Sequence Psychology
Email 1: The Opening
Goal: Establish relevance, create curiosity Approach: Problem-focused, not product-focused Length: 50-80 words
Email 2: The Follow-Up
Goal: Add credibility via social proof Approach: "Here's what happened when..." Length: 60-100 words
Email 3: The Pivot
Goal: Try different angle Approach: Different pain point or benefit Length: 50-80 words
Email 4: The Soft Breakup
Goal: Create scarcity without desperation Approach: "If this isn't a priority..." Length: 40-60 words
Email 5: The Breakup
Goal: Last attempt, leave door open Approach: Value-add (resource) + clear close Length: 50-80 words
