email-sequence（电子邮件序列）

Email Sequence Designer

Designs complete email automation sequences with strategic timing, persuasive copy, and conditional logic.

Quick Reference

Execution Protocol

Step 1: Load Context

Read the business profile for context:

• email-profile.md (project root)

Load reference files for frameworks and benchmarks:

• references/copy-frameworks.md
• references/benchmarks.md

Step 2: Gather Sequence Requirements

Ask the user:

1. Sequence type: welcome, nurture, re-engagement, abandoned-cart, post-purchase, review-request, or custom
2. If custom: goal, trigger event, desired email count, preferred cadence, tone

Confirm business context from profile:

• Industry
• Target audience
• Brand voice
• Primary offer/product

Step 3: Design Sequence Architecture

Based on sequence type, define:

• Total number of emails
• Timing between emails
• Framework assignment per email
• Conditional logic rules
• KPI targets

Step 4: Generate Each Email

For each email in sequence, create:

1. Position and timing: Email X, Day Y or Hours after trigger
2. Subject lines: 3 variants with scores (60-100)
3. Preheader text: 30-80 characters
4. Email body: Full copy following assigned framework
5. CTA: Button text and link placeholder
6. Conditional logic: What happens based on engagement

Step 5: Add Implementation Guidance

Include:

• Platform setup notes
• A/B test recommendations
• KPI benchmarks for this sequence type
• Segment considerations

7. Custom Sequence

For custom sequences, ask user:

1. Goal: What should this sequence accomplish?
2. Trigger event: What starts this sequence?
3. Email count: How many emails?
4. Cadence: How often should emails send?
5. Tone: Formal, casual, urgent, educational?

Design sequence architecture based on responses.

Conditional Logic Rules

Apply these rules to every sequence:

Engagement-Based Branching

If opened previous email but didn't click:

• Emphasize CTA more strongly
• Add social proof elements
• Simplify the ask

If clicked previous email:

• Move faster in sequence
• Skip reminder emails
• Advance to stronger offer

If no engagement on 2+ consecutive emails:

• Slow down cadence
• Change subject line approach
• Test different framework

If unsubscribed:

• Stop sequence immediately
• Remove from all active lists

Time-Based Branching

If cart value is high (e.g., over $200):

• Extend abandoned cart sequence
• Add personal outreach email

If first purchase:

• Trigger post-purchase sequence
• Add to VIP nurture track

If repeat customer:

• Skip welcome emails
• Go straight to loyalty sequence

Quality Checklist

Before delivering sequence, verify:

• Each email has 3 subject line variants
• Preheaders are 30-80 characters

• Conditional logic is defined for each email
• Timing makes sense for business type
• KPI targets are realistic
• A/B test recommendations are specific
• Implementation notes include platform setup

Framework Quick Reference

Load ../../references/copy-frameworks.md for detailed structures:

• PAS: Problem -> Agitate -> Solution
• AIDA: Attention -> Interest -> Desire -> Action
• BAB: Before -> After -> Bridge
• FAB: Features -> Advantages -> Benefits
• 4Ps: Picture -> Promise -> Prove -> Push
• Direct: Straightforward, no persuasion layer (transactional emails)

Notes

• Always adapt sequence length and cadence to business context
• B2B sequences should be longer (nurture over 8-12 weeks)
• E-commerce can be more aggressive (faster cadence)
• Service businesses benefit from educational content
• Always include easy unsubscribe option
• Test sequences with small segment before full deployment
• Monitor sender reputation metrics (bounce rate, complaint rate)
• Apple Mail Privacy Protection makes open tracking unreliable - focus on clicks
• Use sunset policies: remove non-engaged subscribers after 6-12 months

Integration with Other Skills

• Use /email audit to verify domain deliverability before launching sequences
• Use /email write for individual email drafts or rewrites
• Use /email review to score and optimize each email in the sequence
• Use /email plan to align sequences with overall marketing strategy
