Tools Required
This skill runs using CORE memory only. No integrations required.Trigger
Run on demand when the user needs to design an email sequence, onboarding flow, nurture campaign, or lifecycle automation.Setup
Search memory for:- “What type of email sequence does the user need (welcome, nurture, re-engagement, onboarding)?”
- “Who is the target audience for this sequence?”
- “What’s the primary conversion goal?”
“To design the right email sequence, I need to know: What’s the purpose of this sequence (welcome new users, nurture leads, re-engage inactive, post-purchase onboarding)? And what’s the primary goal (activation, conversion, retention)?”Store in memory. Do not ask again.
Step 1: Define Sequence Type and Goals
Identify which sequence type the user needs:- Welcome/onboarding — For new users/customers; goal is activation
- Lead nurture — For prospects; goal is conversion to customer
- Re-engagement — For inactive users; goal is reactivation
- Post-purchase — For customers; goal is adoption/upgrade
- Educational — For audiences; goal is authority/engagement
- Event-based — Triggered by user behavior; goal varies
- Primary conversion goal — What action defines success?
- Audience — Who receives this sequence? What do they know/expect?
- Trigger — What event enters someone into the sequence?
- Exit conditions — When do they leave the sequence?
Step 2: Map Email Sequence Structure
Design the sequence length and cadence:| Type | Length | Timing | Goal |
|---|---|---|---|
| Welcome | 5-7 emails | 1-2 days apart early, then spread out | Activate + convert |
| Lead nurture | 6-8 emails | 2-4 days apart | Build trust → convert |
| Re-engagement | 3-4 emails | 5-7 days apart | Reactivate or list clean |
| Post-purchase | 5-7 emails | Day 1, 3, 7, 14, 30 | Drive adoption + upgrade |
- Position — Which email in the sequence?
- Trigger — When does it send? (Delay after previous, behavior-triggered)
- Primary job — One purpose per email (not everything)
- Goal — What’s the main CTA / action?
Step 3: Design Each Email
For each email in the sequence: Subject line- 40-60 characters
- Clear benefit or curiosity (not clickbait)
- Test 2-3 options per email
- Captures attention (question, statement, pattern interrupt)
- Relevant to recipient
- Lead with value or relevance
- 50-300 words depending on email type
- Short paragraphs (1-3 sentences)
- Conversational tone
- One primary button/link per email
- Action-oriented language
- Clear outcome (what they get)
- Email 1 (immediate): Deliver promised value + quick win
- Email 2 (day 2): Success story or social proof
- Email 3 (day 4): Address common objection
- Email 4 (day 7): Feature deep-dive or use case
- Email 5 (day 11): Limited-time offer or upgrade pitch
- Email 6 (day 14): Final CTA with risk reversal
Step 4: Add Personalization and Segmentation
Determine what personalization is possible:- Merge fields — , ,
- Behavior segmentation — Different emails based on user actions
- Preference segmentation — Different content by use case or industry
- Skip logic — Skip emails if certain conditions are met
Step 5: Create Implementation Plan
Specify how the sequence will be set up:- Email platform — Where will it live? (Customer.io, Mailchimp, SendGrid, etc.)
- Trigger/entry point — How do people enter? (Signup form, event, manual, segment)
- Timing — Delays between emails
- Personalization/merge fields — What’s available?
- Unsubscribe/exit — When can they leave?
- Metrics to track — Open rate, click rate, conversion, unsubscribe
Step 6: Document and Deliver
Provide complete sequence documentation.Output Format
Email Sequence: [Sequence Name]
Type: [Welcome / Lead Nurture / Re-engagement / Post-purchase] Trigger: [Event that enters someone into this sequence] Goal: [Primary conversion action] Length: [# emails] Timing: [Delay between emails] Exit conditions: [When they leave]Email 1: [Name/Purpose]
Send: [Timing] Subject: [Subject line option A] — [Why it works] Alt subjects: [Option B], [Option C] Content: [Hook/opening line] [Body copy] CTA Button: [Text] → [Destination]Email 2: [Name/Purpose]
[Same structure]Metrics & Success
| Metric | Target | Notes |
|---|---|---|
| Open rate | [expected %] | Benchmark by type |
| Click rate | [expected %] | Engagement signal |
| Conversion | [#] | Primary success metric |
| Unsubscribe rate | <0.5% | Monitor for relevance |
Edge Cases
- No segmentation capability — Keep subject lines and copy generic but personal (use name at minimum). Layer segmentation once platform supports it.
- Audience is mixed (different personas) — Create separate sequences per persona rather than one generic sequence. Different audiences need different messaging.
- Too many emails planned — Test with fewer emails first. More emails = higher unsubscribe risk. Start with 4-5, expand after proving value.
- Users not entering the sequence — Verify trigger is set up correctly. Test with manual entry first to confirm email content works.
- High unsubscribe rate early — First email isn’t delivering on the promise. Revisit the value prop and subject line; users may have wrong expectations.
Initial Assessment
Check for product marketing context first: If.agents/product-marketing-context.md exists (or .claude/product-marketing-context.md 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
- 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
- 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)
- 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
