emails

An agent skill by coreyhaines31, from coreyhaines31/marketingskills. Tags: automation, copywriting, email, marketing, workflow.

What it does

When the user wants to create or optimize an email sequence, drip campaign, automated email flow, or lifecycle email program. Also use when the user mentions "email sequence," "drip campaign," "nurture sequence," "onboarding emails," "welcome sequence," "re-engagement emails," "email automation," "lifecycle emails," "trigger-based emails," "email funnel," "email workflow," "what emails should I send," "welcome series," or "email cadence." Use this for any multi-email automated flow. For cold outreach emails, see cold-email. For in-app onboarding, see onboarding.

Install

With the skills CLI, which installs into Claude Code, Codex, Cursor and other agents:

npx skills add coreyhaines31/marketingskills --skill emails

Or copy the skill folder into Claude Code's skills directory by hand (~/.claude/skills for every project, or .claude/skills inside one):

git clone --depth 1 https://github.com/coreyhaines31/marketingskills
cp -r marketingskills/skills/emails ~/.claude/skills/emails

Safety box score

Grade B, low risk: 11 of 100 risk points, rated 2026-10-15. The grade rates what the skill and its scripts can reach on the machine of whoever installs it, across eight categories from shell execution to secrets access. How the score works.

This skill is a documentation-only email marketing copilot: it drafts lifecycle email sequences, copy, timing, and segmentation for welcome, nurture, onboarding, re-engagement, billing, and campaign flows. The main risks are modest reads of local context files and linked external docs, plus the inherent business impact of designing automated customer emails once implemented elsewhere.

Category levels, from 0 (none) to 3 (high)
Category	Level	Why
Code & shell execution	0 (none)	No shell commands, code evaluation, or native scripts are present in `SKILL.md` or the referenced markdown files.
Network access	1 (low)	The skill links to external GitHub pages for the tools registry and integration guides, e.g. `https://github.com/coreyhaines31/marketingskills/blob/main/tools/REGISTRY.md`, but it does not itself fetch remote content.
Filesystem reach	1 (low)	It explicitly tells the agent to read optional local context files such as `.agents/product-marketing.md`, `.claude/product-marketing.md`, or `product-marketing-context.md` before proceeding.
Secrets & credentials	0 (none)	There is no instruction to collect, read, print, or use passwords, API keys, `.env` files, browser sessions, or other secrets.
Privilege & persistence	0 (none)	Nothing asks for sudo, global installs, services, shell startup edits, or other privilege-changing actions.
Instruction hijack surface	0 (none)	I found no prompt-injection payloads, hidden text, or instructions to ignore higher-priority rules or conceal behavior.
Irreversible actions	1 (low)	The skill designs multi-step automated email flows, including post-purchase, billing, re-engagement, and trigger-based sequences, but it does not itself send them.
Transparency	0 (none)	All provided skill files are plain markdown; there are no binaries, minified blobs, or decoded-at-runtime content.

Before installing

Open `SKILL.md` and confirm it only drafts email strategy/copy, not sending or automation actions.
Check whether your agent can read `.agents/product-marketing.md` or `.claude/product-marketing.md`; move sensitive notes out if needed.
Review the linked tools registry and integration guides before connecting any live email account or API token.
