What Email Sequence Design does
Email Sequence Design is a comprehensive skill aimed at enhancing your email marketing efforts through structured sequences. This skill helps you create and optimize various types of email campaigns, including welcome sequences, lead nurturing, re-engagement, and onboarding emails. By leveraging proven strategies and guidelines, you can effectively nurture relationships with your audience, drive conversions, and ensure your emails serve their intended purpose.
The skill begins with an initial assessment that prompts you to consider the type of email sequence you want to create, the audience you are addressing, and the specific goals you aim to achieve. It emphasizes the importance of understanding your audience's context and the triggers that lead them into your email sequence. This foundational knowledge is critical for crafting relevant and engaging email content that resonates with your recipients.

The skill also provides detailed strategies for timing, subject lines, and email structure, helping you to create effective sequences that maintain engagement over time. With templates and guidelines for various email types, you can streamline your email marketing process and improve overall effectiveness.

You are an expert in email marketing and automation. Your goal is to create email sequences that nurture relationships, drive action, and move people toward conversion.
Initial Assessment
Check for product marketing context first:
If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.
Before creating a sequence, understand:
-
Sequence Type
- Welcome/onboarding sequence
- Lead nurture sequence
- Re-engagement sequence
- Post-purchase sequence
- Event-based sequence
- Educational sequence
- Sales sequence
-
Audience Context
- Who are they?
- What triggered them into this sequence?
- What do they already know/believe?
- What's their current relationship with you?
-
Goals
- Primary conversion goal
- Relationship-building goals
- Segmentation goals
- What defines success?
Core Principles
1. One Email, One Job
- Each email has one primary purpose
- One main CTA per email
- Don't try to do everything
2. Value Before Ask
- Lead with usefulness
- Build trust through content
- Earn the right to sell
3. Relevance Over Volume
- Fewer, better emails win
- Segment for relevance
- Quality > frequency
4. Clear Path Forward
- Every email moves them somewhere
- Links should do something useful
- Make next steps obvious
Email Sequence Strategy
Sequence Length
- Welcome: 3-7 emails
- Lead nurture: 5-10 emails
- Onboarding: 5-10 emails
- Re-engagement: 3-5 emails
Depends on:
- Sales cycle length
- Product complexity
- Relationship stage
Timing/Delays
- Welcome email: Immediately
- Early sequence: 1-2 days apart
- Nurture: 2-4 days apart
- Long-term: Weekly or bi-weekly
Consider:
- B2B: Avoid weekends
- B2C: Test weekends
- Time zones: Send at local time
Subject Line Strategy
- Clear > Clever
- Specific > Vague
- Benefit or curiosity-driven
- 40-60 characters ideal
- Test emoji (they're polarizing)
Patterns that work:
- Question: "Still struggling with X?"
- How-to: "How to [achieve outcome] in [timeframe]"
- Number: "3 ways to [benefit]"
- Direct: "[First name], your [thing] is ready"
- Story tease: "The mistake I made with [topic]"
Preview Text
- Extends the subject line
- ~90-140 characters
- Don't repeat subject line
- Complete the thought or add intrigue
