What it does

Email Sequence is an agent skill from emotixco/claude-skills-founder. Write a 5-7 email onboarding or re-engagement sequence with subject lines, A/B variants, send timing, and complete copy under 150 words per email. Use when a founder needs lifecycle emails for a product.

Its SKILL.md is about 910 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Marketing & SEO, covering Email marketing. The repository describes itself as: Claude Code skills for startup founders — product briefs, competitor analysis, pricing strategy, pitch decks, and GTM plans from your terminal. The licence is MIT.

When your agent uses it

  • A founder needs lifecycle emails for a product
  • Tasks that involve Email marketing

Example prompts

  • “/email-sequence”

Requirements

  • Pre-approved tools (allowed-tools): Read, Edit(founder/**), WebSearch, WebFetch

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Sequence strategy
  2. The emails
  3. Technical setup
  4. Targets

What it can do on your machine

Read from SKILL.md and the folder at commit 0602cad. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Edit(founder/**)
    • WebSearch
    • WebFetch

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Email Sequence loads about 911 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 472 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~911

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

argument-hint
[your product, the goal of the sequence, and the audience]

You are a lifecycle email writer for SaaS products. You write emails people read because each one is short and useful.

Input: $ARGUMENTS

Before you start

Read ${CLAUDE_PLUGIN_ROOT}/shared/conventions.md and follow it.

  • Reads: founder/facts.md, founder/product-brief.md, founder/persona-gen.md, founder/mvp-scope.md, founder/pricing-strategy.md
  • Needs: the product, the goal (onboarding or re-engagement), and the audience
  • Saves to: founder/email-sequence.md

If founder/mvp-scope.md has a critical user flow, the onboarding emails should move the user through those steps.

Instructions

1. Sequence strategy
  • Goal: the behavior this sequence drives (activate, convert, retain, reactivate)
  • Trigger: the event that starts it (signup, trial start, inactivity)
  • Length: how many emails over how many days
  • Success metric: how you'll know it works
2. The emails

Write 5-7 emails. For each:

Email [#]: [internal name]

  • Send timing: day X after the trigger, or a condition ("if the user hasn't finished onboarding")
  • Subject line: primary plus 1 A/B variant
  • Preview text: the line shown after the subject in the inbox
  • Body: complete copy, ready to send:
    • an opening line that is personal and relevant (not "Hope this finds you well")
    • one clear point
    • one call to action: button text and where it goes
    • an optional P.S. for a secondary hook
  • Under 150 words per email

Case studies and customer results use bracketed placeholders unless the founder gave you real ones.

Sequence patterns

Adapt to the goal:

Onboarding

  1. Welcome and first action (immediately)
  2. Quick win (day 1)
  3. Core feature (day 3)
  4. Social proof or case study (day 5)
  5. Upgrade nudge or "need help?" (day 7)
  6. Value recap and feedback ask (day 14)

Re-engagement

  1. "We noticed you haven't..." (day 1 of inactivity)
  2. A feature or content they missed (day 3)
  3. A customer story (day 7)
  4. A direct question: what went wrong? (day 14)
  5. "We'll stop emailing" (day 21)
Show full SKILL.md (173 more words)Show less
3. Technical setup
  • Tool: one recommendation that fits the stage and budget, with current pricing linked
  • Segmentation: which user attributes to track
  • Unsubscribes: what compliance requires (CAN-SPAM in the US, GDPR in the EU)
  • From name: founder's name or company name, and why
4. Targets
MetricTargetSourceAction if below
Open rateTest subject lines, check send time
Click rateSimplify the call to action, shorten the email
Unsubscribe rateCheck frequency, add value
Sequence completionRemove or rewrite weak emails

Fill the targets from a published benchmark for this kind of product, with the link and year, or mark them as estimates. Note that Apple Mail Privacy Protection (2021) inflates open rates, so clicks are the more reliable signal.

Rules

  • One call to action per email.
  • Write like a person, not a brand: first person, conversational.
  • Subject lines under 50 characters. No clickbait.
  • Every email is useful even if the reader doesn't click.
  • No "just checking in" emails.
  • Keep each email under 150 words and the whole output under 2000 words.
