emails

Use it when:
You need a welcome, lead nurture, onboarding, re-engagement or other automated email flow, or want to find gaps in your lifecycle emails.
It does:
Asks what triggers the sequence, who's in it and its goal, then sets the length, spacing and one job for each email.
You get:
A sequence overview with trigger, goal and exit conditions, then each email's send time, subject, preview text, body and button, plus a metrics plan.
Bans:
AI tells such as "it's not X, it's Y", "no X, no Y" lists, fake "Re:" subject lines and "I hope this email finds you well".
Unlike cold-email:
That one, from the same repo, handles cold outreach; this one designs flows triggered by signups, purchases, events or inactivity.

TL;DR

Email sequence design for lifecycle marketing. It first reads your product marketing context if you have it (a shared file on your product, audience and positioning that the repo's product-marketing skill writes), including its Learnings section, so angles and offers already tested aren't proposed again as new. Four principles run through every sequence: one email, one job; value before the ask; fewer, more relevant emails; and an obvious next step. It gives default lengths and spacing, such as 5 to 7 welcome emails over about two weeks, or 3 to 4 re-engagement emails after 30 to 60 days of inactivity, with an email-by-email outline for welcome, lead nurture, re-engagement and onboarding sequences. Copy rules cover structure (hook, context, value, call to action, sign-off), short mobile-friendly paragraphs, word counts by email type, and subject lines of 40 to 60 characters. It lists lifecycle emails by category, from failed-payment recovery to win-back, and loads references for detailed templates, the lifecycle audit, and personalization and testing. For sending, it points to guides for tools such as Customer.io, Mailchimp, Resend and Kit.

Email Sequence Design

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.

Reference Routing

Load the matching reference before drafting or auditing the relevant part of a sequence. Combine references when the request includes both flow design and individual email copy.

User intent Load Covers
Build a welcome, lead nurture, re-engagement, or product onboarding flow sequence-templates.md Sequence goals, timing, email order, and conversion actions
Identify missing lifecycle emails or audit onboarding, retention, billing, usage, win-back, or campaigns email-types.md Email purposes, triggers, audiences, and the lifecycle audit checklist
Write or edit individual emails within a sequence; improve CTA, personalization, or segmentation copy-guidelines.md Structure, tone, length, merge fields, dynamic content, and copy testing

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.

Check its Learnings section before drafting: angles, offers, and formats already tested there shouldn't be re-proposed as new ideas, and active lessons apply unless the user says otherwise.

Before creating a sequence, understand:

  1. Sequence Type

    • Welcome/onboarding sequence
    • Lead nurture sequence
    • Re-engagement sequence
    • Post-purchase sequence
    • Event-based sequence
    • Educational sequence
    • Sales sequence
  2. Audience Context

    • Who are they?
    • What triggered them into this sequence?
    • What do they already know/believe?
    • What's their current relationship with you?
  3. 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

Email Copy Guidelines

Structure
  1. Hook: First line grabs attention
  2. Context: Why this matters to them
  3. Value: The useful content
  4. CTA: What to do next
  5. Sign-off: Human, warm close
Formatting
  • Short paragraphs (1-3 sentences)
  • White space between sections
  • Bullet points for scanability
  • Bold for emphasis (sparingly)
  • Mobile-first (most read on phone)
Tone
  • Conversational, not formal
  • First-person (I/we) and second-person (you)
  • Active voice
  • Read it out loud. Does it sound like a person?
No AI Tells

Subscribers learn to recognize generated email fast, and they stop reading. Write from the specific thing you want them to know or do.

Never write these:

  • Contrast reveals: "It's not X, it's Y." "Not because X. Because Y." State Y directly, with the reason.
  • Negation lists: "No X, no Y, no Z." Say what does happen. One plain absence ("No card required") is fine.
  • Trailing pile-ons: a full claim, then a comma and more restating clauses. End the sentence at the claim.
  • Self-answered questions and colon reveals: "The result? 3x faster." "The best part: it learns." FAQ questions and a question in the reader's own voice are fine.
  • Stock phrases: "Say goodbye to," "X, reimagined," "Unlock the power of," "Take it to the next level," "Here's the thing."
  • Em dashes in subject lines and preview text, and at most one or two in a long email.

Email-specific tells:

  • Subject-line bait: fake "Re:" or "Fwd:", "You won't believe...", "🔥 Big news." The subject should hold up if it's the only line they read.
  • Stock openers: "I hope this email finds you well," "Just checking in," "Great news!" Open with the reason you're writing.
  • Sign-off filler: "Feel free to reach out if you have any questions." Ask for one specific action, or end.

For the full blacklist, use the copywriting skill's AI-tells reference.

Length
  • 50-125 words for transactional
  • 150-300 words for educational
  • 300-500 words for story-driven
CTA Guidelines
  • Buttons for primary actions
  • Links for secondary actions
  • One clear primary CTA per email
  • Button text: Action + outcome
