Pre-send quality review scoring subject lines, copy, HTML rendering, dark mode compatibility, and compliance.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `references/benchmarks.md`, `references/compliance.md` and `references/copy-frameworks.md`).

It sits in Marketing & SEO, covering Email management, Email marketing and Transactional email. It works with Model Context Protocol and Gmail. The repository describes itself as: AI-powered email management and marketing skill for Claude Code. Inbox triage, composition, quality review, deliverability audit, automation sequences, and marketing strategy. The licence is MIT.

When your agent uses it

  • Email marketing
  • Tasks that involve Email management
  • Tasks that involve Email marketing

Example prompts

  • “check email”
  • “write email”
  • “compose”
  • “/email”

Requirements

  • Pre-approved tools (allowed-tools): Read, Grep, Glob, Bash, WebFetch, WebSearch

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Check for email-profile.md in project root
  2. If missing, run first-time onboarding (see User Profile System below)
  3. If profile exists, detect available MCP servers (Gmail, Outlook, SendGrid)
  4. Show interactive menu with inbox summary if email MCP is available

What it can do on your machine

Read from SKILL.md and the folder at commit 182270a. 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
    • Grep
    • Glob
    • Bash
    • WebFetch
    • WebSearch

    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 loads about 2k tokens when it runs, and up to ~21k if it reads all its reference files. Until then it costs about 239 tokens; SKILL.md has 721 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~239
When it runs · the whole SKILL.md, loaded when a task matches
~2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~21k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Grep, Glob, Bash, WebFetch, WebSearch

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.

Email -- Universal Email Management & Marketing Skill

Comprehensive email management across all business types (local services, SaaS, e-commerce, creators, agencies). Orchestrates 6 specialized sub-skills and 4 subagents.

Quick Reference

CommandWhat it does
/emailInteractive mode: detect context, show inbox summary or menu
/email checkInbox triage: scan, score importance, categorize, suggest replies
/email writeCompose email: choose framework, generate subject + body + HTML
/email review <email>Pre-send quality check: score subject, copy, HTML, compliance
/email audit <domain>Deliverability audit: SPF/DKIM/DMARC, blacklists, compliance
/email sequence <type>Design automation: welcome, nurture, win-back, cart, custom
/email plan <business>Email marketing strategy with industry template

Orchestration Logic

Interactive Mode (/email)

When invoked without arguments:

  1. Check for email-profile.md in project root
  2. If missing, run first-time onboarding (see User Profile System below)
  3. If profile exists, detect available MCP servers (Gmail, Outlook, SendGrid)
  4. Show interactive menu with inbox summary if email MCP is available
Command Routing

For specific commands, load the relevant sub-skill directly:

  • /email check -> skills/email-check/SKILL.md
  • /email write -> skills/email-write/SKILL.md
  • /email review -> skills/email-review/SKILL.md
  • /email audit -> skills/email-audit/SKILL.md
  • /email sequence -> skills/email-sequence/SKILL.md
  • /email plan -> skills/email-plan/SKILL.md
Audit Delegation

When the user invokes /email audit, delegate to subagents in parallel:

  1. Run scripts/check_deliverability.py for DNS-based checks
  2. Spawn subagents: email-deliverability, email-compliance
  3. Collect results and generate unified Email Health Score (0-100)
  4. Create prioritized fix list (Critical -> High -> Medium -> Low)

User Profile System

On first run, generate email-profile.md in the project root:

  1. Detect existing MCP configurations:
    • Check for Gmail MCP tools (search_gmail_messages, send_gmail_message)
    • Check for Outlook MCP tools (list-mail-messages, send-mail)
    • Check for marketing MCPs (SendGrid, Mailchimp, Kit.com)
  2. Ask 4 setup questions:
    • Business type: local business, SaaS, ecommerce, creator, agency, personal
    • Primary email platform: Gmail, Outlook, other
    • Compliance regions: US only, EU/GDPR, both
    • Brand voice: professional, friendly, casual, authoritative
  3. Generate email-profile.md with these settings
  4. All sub-skills reference this profile to adapt recommendations
Profile-Driven Behavior
Business TypeEmphasis
Local businessReview requests, appointment reminders, loyalty, seasonal promos
SaaSOnboarding sequences, feature announcements, churn prevention, NPS
EcommerceAbandoned cart, post-purchase, promotional, cross-sell/upsell
CreatorNewsletter, community engagement, monetization, content teasers
AgencyClient communication, project updates, case studies, proposals
PersonalInbox management, reply drafts, organization

  • Subject lines: 6-10 words / 30-50 characters
  • Spam complaint rate must stay under 0.1% (hard limit: 0.3%)
  • Bounce rate must stay under 2% (ideal: under 1%)
  • HTML email total size under 102 KB (Gmail clips larger emails)
  • Image-to-text ratio: minimum 60% text / 40% images
  • Every marketing email must include unsubscribe mechanism
  • Every marketing email must include physical postal address (CAN-SPAM)
  • One-click unsubscribe headers required (RFC 8058) for bulk senders
  • Honor unsubscribe requests within 2 business days
  • Never send more than 20 emails per session without explicit approval
  • Always show email draft for approval before sending

MCP Integration

Detecting Available MCP Tools
