How to use the Email Sequence Design agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The Email Sequence Design skill (skill name: emails) gives an AI agent the working method of an email marketing specialist for multi-email flows such as welcome series, lead nurture, re-engagement and onboarding. This guide is for marketers, founders and small teams who want a clear sequence plan and draft copy without starting from a blank page. By the end you will know how to install the skill, trigger it with a plain request and check the output.
Email Sequence Designcoreyhaines31/marketingskills · MIT Download the skill Quick start
- 1Download and unzip the skill. Download the ZIP from the directory page and unzip it into ~/.claude/skills/ or a project's .claude/skills/ folder.
- 2Or upload it in the Claude apps. Open Settings, go to Capabilities, then Skills, and upload the skill.
- 3Describe your flow. State the audience, the trigger that starts the sequence and the goal, such as a conversion or activation.
- 4Answer the agent's questions. The agent asks about sequence type, audience context and success measures before drafting.
- 5Review the proposed plan. Check the email count, timing, order and the single call to action in each email.
- 6Refine individual emails. Ask for edits to a specific email's hook, CTA or length, and check the draft against the no-AI-tells rules.
- 7Build it in your email tool. Set up the triggers, delays and emails in your own platform, since the skill does not send anything.
What is an agent skill and what does this one make the agent do?
An agent skill is a folder of instructions and reference files that an AI agent loads when a request matches the skill's description. This one lives in a SKILL.md file with supporting guides in a references folder.
When it is active, the agent acts like an email marketing expert for any automated multi-email flow. It asks about the audience, the trigger and the goal, then proposes a sequence with the number of emails, timing, order and one clear call to action per email. It also loads reference guides on sequence templates, lifecycle email types and copy style, and avoids certain AI-sounding writing patterns and fake 'Re:' subject lines.
- Sequence types it covers: welcome or onboarding, lead nurture, re-engagement, post-purchase, event-based, educational and sales.
- Typical lengths in the source: welcome 3-7 emails, lead nurture 5-10, onboarding 5-10, re-engagement 3-5.
- Lifecycle email types it can audit: onboarding, retention, billing, usage, win-back and campaign emails.
Install the emails skill
Download the ZIP for the skill from the directory page and unzip it. For a personal setup, place the unzipped folder in ~/.claude/skills/. For a single project, place it in that project's .claude/skills/ folder.
If you use the Claude apps instead, open Settings, go to Capabilities, then Skills, and upload the skill there.
- Personal install: ~/.claude/skills/ (available across your projects).
- Project install: .claude/skills/ inside the project folder.
- Claude apps: Settings → Capabilities → Skills, then upload.
How to trigger the skill with a natural request
You do not need a special command. The skill loads when your request matches its description. Plain requests that mention an email sequence, drip campaign, welcome series, onboarding emails, re-engagement emails or 'what emails should I send' are the intended triggers.
The more context you give, the better the plan. Name the audience, what started their journey and the goal. The agent will ask for anything missing, and it will check for a product marketing context file if one exists in your project.
- Good: 'Build a 6-email welcome series for people who sign up for a free trial of our project tool. The goal is to get them to invite a teammate.'
- Good: 'What lifecycle emails am I missing? We have onboarding and billing emails but nothing for win-back.'
- Weaker: 'Write some emails.' Add the trigger, audience and goal first.
Examples of what you can ask for
The skill is built for multi-email flows. Use it when more than one email is planned, not for a single one-off newsletter.
For a re-engagement flow, ask for a sequence triggered by inactivity. The source suggests a trigger of 30-60 days of inactivity and a structure of check-in, value reminder, incentive and last chance. For a product onboarding flow, the source suggests 5-7 emails over 14 days and notes that email should support in-app onboarding rather than duplicate it.
- Welcome series after signup with the first email delivering the promised value.
- Lead nurture for prospects who downloaded a resource, moving toward an offer.
- Re-engagement for dormant subscribers, ending with a stay-or-unsubscribe email.
- Audit of which billing, retention or win-back emails are missing from your lifecycle program.
- Copy review of an existing email to tighten the hook, CTA and sign-off.
What the skill needs and how it stays safe
The skill lists no required dependencies. It does not run scripts and does not use the network. It writes plans and copy only.
It does not connect to an email platform, so it cannot send, schedule or import anything for you. You will build the automation in your own email tool and paste or adapt the copy there.
- Requires: nothing listed.
- Runs scripts: no.
- Uses network: no.
- Does not send or schedule emails. Use it for plans and draft copy only.
- Not for cold outreach (the source points to a separate cold-email skill) or in-app onboarding screens (a separate onboarding skill).
Tips for better sequences
The skill's core rule is one email, one job, with one main call to action. Ask the agent to check each draft against that rule. Its copy guidance also favours short paragraphs, mobile-first layout and a conversational tone.
The skill asks you to avoid several AI-sounding patterns: contrast reveals such as 'it's not X, it's Y', lists of 'no X, no Y, no Z', trailing pile-ons, self-answered questions and fake 'Re:' subject lines. Check drafts for these before you use them.
- Give the agent your existing subject lines and results so it does not repeat tested ideas, if you keep them in a product marketing context file.
- Keep subject lines clear and specific, about 40-60 characters, as the source suggests.
- Test emoji in subject lines, since the source notes they are polarising.
- Follow the source's timing guidance: welcome email immediately, early emails 1-2 days apart, nurture 2-4 days apart.
- Ask for merge field and segmentation suggestions when you write individual emails.
What people use it for
- A SaaS team builds a 7-email welcome series that moves new trial users from signup to a first key action.
- A founder creates a lead nurture flow for people who downloaded a guide, ending with a direct offer.
- A marketing lead audits the lifecycle program and finds no win-back emails for cancelled customers.
- An ecommerce or subscription team drafts a re-engagement flow for subscribers inactive for 30-60 days.
- A product team plans an onboarding email series that supports, rather than repeats, its in-app guidance.
Frequently asked questions
How do I install the emails agent skill?
Download the ZIP from the directory page and unzip it into ~/.claude/skills/ for a personal setup, or into a project's .claude/skills/ folder for one project. In the Claude apps, you can instead upload it under Settings → Capabilities → Skills.
Does the emails skill require anything else to run?
The skill lists no required dependencies. It does not run scripts and does not use the network, so it works by giving the agent instructions and reference files.
Is the emails skill free and what is its licence?
The skill is published under the MIT licence. The source does not state pricing, so check the directory page for any cost details.
Can the skill send or schedule my emails?
No. The skill only writes plans and copy and does not connect to an email platform. You set up the sequence and timing in your own email tool.
Should I use this skill for cold outreach?
No. The skill says cold outreach and outbound sequences belong to a separate cold-email skill. For in-app onboarding screens or tooltips, it points to a separate onboarding skill.
Why does the agent avoid certain phrases and fake 'Re:' subject lines?
The skill's copy guidelines state that subscribers learn to recognise generated email quickly and stop reading. It asks the agent to avoid patterns like contrast reveals, negation lists and fake 'Re:' subject lines.

Our verdict
Use this skill if you are planning or auditing a welcome, onboarding, nurture, re-engagement or lifecycle email flow and want a structured plan with one clear call to action per email. Pick a different tool if you need cold outreach, which has its own skill, in-app onboarding, or a system that actually sends and schedules emails, since this skill does none of those.
