Mailchimp CLI

Every Mailchimp endpoint plus the workflow commands the API forces you to compose yourself.

Mailchimp's REST API has 291 endpoints and an SDK in every language, but composes nothing — subscribing a contact with tags takes three calls and an MD5 hash; checking whether a campaign worked takes four endpoints joined by hand; bulk imports require decoding tar.gz JSONL from a 10-minute expiring URL. This CLI ships every endpoint as a typed command plus eight novel workflow commands that compose the API the way humans and agents actually use it: subscribe-with-tags in one call, CSV bulk subscribe with batch decode, single and multi-campaign digests with --md for pasting into weekly review docs, head-to-head campaign comparison, segment health audit, send-checklist CI gate, e-commerce attribution, and per-domain deliverability rollup. A local SQLite cache makes every audience SQL-queryable, and the MCP surface uses code orchestration so an agent loads the whole API in ~1K tokens.

Install

The recommended path installs both the mailchimp-pp-cli binary and the pp-mailchimp agent skill (Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, and other agents supported by the upstream skills CLI) in one shot:

npx -y @mvanhorn/printing-press-library install mailchimp

For CLI only (no skill):

npx -y @mvanhorn/printing-press-library install mailchimp --cli-only

For skill only — installs the skill into the same agents as the default command above, but skips the CLI binary (use this to update or reinstall just the skill):

npx -y @mvanhorn/printing-press-library install mailchimp --skill-only

To constrain the skill install to one or more specific agents (repeatable — agent names match the skills CLI):

npx -y @mvanhorn/printing-press-library install mailchimp --agent claude-code
npx -y @mvanhorn/printing-press-library install mailchimp --agent claude-code --agent codex

Without Node (Go fallback)

If npx isn't available (no Node, offline), install the CLI directly via Go (requires Go 1.26.4 or newer):

go install github.com/mvanhorn/printing-press-library/library/marketing/mailchimp/cmd/mailchimp-pp-cli@latest

This installs the CLI only — no skill.

Pre-built binary

Download a pre-built binary for your platform from the latest release. On macOS, clear the Gatekeeper quarantine: xattr -d com.apple.quarantine <binary>. On Unix, mark it executable: chmod +x <binary>.

Install for Hermes

Install the CLI binary first. The installer writes binaries to a per-user managed bin directory by default: $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows.

npx -y @mvanhorn/printing-press-library install mailchimp --cli-only

Then install the focused Hermes skill.

From the Hermes CLI:

hermes skills install mvanhorn/printing-press-library/cli-skills/pp-mailchimp --force

Inside a Hermes chat session:

/skills install mvanhorn/printing-press-library/cli-skills/pp-mailchimp --force

Restart the Hermes session or gateway if the newly installed skill is not visible immediately.

Install for OpenClaw

Install both the CLI binary and the focused OpenClaw skill. The installer defaults binaries to a per-user bin directory ($HOME/.local/bin on macOS/Linux, %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows):

npx -y @mvanhorn/printing-press-library install mailchimp --agent openclaw

Restart the OpenClaw session or gateway if the newly installed skill is not visible immediately.

Use with Claude Desktop

This CLI ships an MCPB bundle — Claude Desktop's standard format for one-click MCP extension installs (no JSON config required).

To install:

1. Download the .mcpb for your platform from the latest release.
2. Double-click the .mcpb file. Claude Desktop opens and walks you through the install.
3. Fill in MAILCHIMP_API_KEY (format: key-dc, e.g., abc...-us6) when Claude Desktop prompts you. The CLI parses the -dc suffix to route requests to the correct datacenter.

Requires Claude Desktop 1.0.0 or later. Pre-built bundles ship for macOS Apple Silicon (darwin-arm64) and Windows (amd64, arm64); for other platforms, use the manual config below.

Manual JSON config (advanced)

If you can't use the MCPB bundle (older Claude Desktop, unsupported platform), install the MCP binary and configure it manually.

Install the MCP binary from this CLI's published public-library entry or pre-built release.

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "mailchimp": {
      "command": "mailchimp-pp-mcp",
      "env": {
        "MAILCHIMP_USERNAME": "<your-key>"
      }
    }
  }
}

Authentication

Mailchimp encodes the datacenter in the API key suffix. The key 'abc...xyz-us6' tells the CLI to route requests to 'us6.api.mailchimp.com.' Set MAILCHIMP_API_KEY and the CLI parses the suffix at startup. For OAuth tokens (no embedded suffix), set MAILCHIMP_DC=us1 explicitly or let 'mailchimp auth dc-lookup' resolve it from the metadata endpoint.

Quick Start

# datacenter encoded in the suffix; the CLI parses it
export MAILCHIMP_API_KEY=your-key-us6

# verify auth, dc routing, and API reach
mailchimp-pp-cli doctor

# pull a local copy so search and sql work offline
mailchimp-pp-cli sync --resources lists,members,campaigns,reports

# one-shot upsert with tags, no MD5 dance
mailchimp-pp-cli subscribe alice@example.com --list LIST_ID --tags vip,newsletter

# the four-endpoint join the dashboard buries
mailchimp-pp-cli digest CAMPAIGN_ID --json --select campaign_id,open_rate,click_rate,top_links

# offline FTS over synced audiences, members, campaigns
mailchimp-pp-cli search 'newsletter' --json

Unique Features

These capabilities aren't available in any other tool for this API.

Workflow composition

• subscribe — Upsert a member by email and apply tags in a single command. Auto-computes the MD5 subscriber hash so you never see it.

  When an agent needs to add a contact with tags, this is one call instead of three with MD5 hashing in the middle.

  mailchimp-pp-cli subscribe alice@example.com --list a1b2c3d4e5 --tags vip,onboarding --merge FNAME=Alice

• bulk-subscribe — Read a CSV, fan out through Mailchimp's /batches endpoint (the official 10-concurrent-connection escape hatch), poll until done, decode the tar.gz of JSONL results within the 10-minute response URL window, and print per-row outcomes.

  When an agent needs to subscribe more than ~50 contacts at once, this is the only safe path that respects rate limits and gives back actionable per-row results.

  mailchimp-pp-cli bulk-subscribe --csv contacts.csv --list a1b2c3d4e5 --tags newsletter --watch

Local joins that compound

• digest — Single-campaign mode (digest ) joins report + email-activity + ecommerce-product-activity into one summary with opens/clicks/bounces/revenue + top-clicked links + top-converted products. Rollup mode (digest --last N or --week) renders a multi-campaign summary table with aggregate stats. --md renders either as paste-ready markdown.

  Use digest for per-campaign analysis; use digest --last N for a weekly rollup. --md is the paste-into-doc shape both personas need.

  mailchimp-pp-cli digest --last 5 --md

• segments audit — Find empty segments, segments that haven't grown in 90 days, and segments not referenced by any recent campaign. Reads the segments endpoint and joins with member counts from the local SQLite store.

  When cleaning up an audience or auditing segmentation hygiene, this surfaces what's dead in one call.

  mailchimp-pp-cli segments audit --list a1b2c3d4e5 --json

• attribution — Join a campaign's e-commerce product activity report with synced store orders to compute attributed revenue, top products by attributed revenue, and conversion rate (orders divided by opens).

  When measuring whether a campaign drove revenue, this is the single command.

  mailchimp-pp-cli attribution 7f8a9b0c1d --store mystore --json

• deliverability — Roll up domain-performance reports across the last N campaigns. Surfaces per-domain (gmail.com, yahoo.com, outlook.com) bounce, spam, open, and click rates. Highlights domains performing below the account average.

  When investigating a deliverability dip, this shows you which inbox providers are degrading without clicking through 10 separate report pages.

  mailchimp-pp-cli deliverability --last 10 --json

• compare — Side-by-side metric diff for two campaigns. Fetches both campaigns' report + email-activity in parallel, renders open rate / CTR / click-to-open / bounces / unsubscribes / revenue with a winner per metric, computes delta, and surfaces top differences (subject line, send time, audience size). --md renders as paste-ready markdown.

  When you ask 'which campaign won?' or 'did the change work?', this is the single command. The --md mode pastes into a weekly review doc.

  mailchimp-pp-cli compare 7f8a9b0c1d 8c9d0e1f2a --md

Operational safety

• send-checked — Run the official send-checklist before sending. Exits 2 with the failing items if any have type=error or is_ready=false; otherwise sends.

  When sending campaigns from a pipeline, this is the safe default — broken campaigns don't ship silently.

  mailchimp-pp-cli send-checked 7f8a9b0c1d

Output Formats

# Human-readable table (default in terminal, JSON when piped)
mailchimp-pp-cli account-exports get

# JSON for scripting and agents
mailchimp-pp-cli account-exports get --json

# Filter to specific fields
mailchimp-pp-cli account-exports get --json --select id,name,status

# Dry run — show the request without sending
mailchimp-pp-cli account-exports get --dry-run

# Agent mode — JSON + compact + no prompts in one flag
mailchimp-pp-cli account-exports get --agent

Agent Usage

This CLI is designed for AI agent consumption:

• Non-interactive - never prompts, every input is a flag
• Pipeable - --json output to stdout, errors to stderr
• Filterable - --select id,name returns only fields you need
• Previewable - --dry-run shows the request without sending
• Explicit retries - add --idempotent to create retries and --ignore-missing to delete retries when a no-op success is acceptable
• Confirmable - --yes for explicit confirmation of destructive actions
• Piped input - write commands can accept structured input when their help lists --stdin
• Offline-friendly - sync/search commands can use the local SQLite store when available
• Agent-safe by default - no colors or formatting unless --human-friendly is set

Exit codes: 0 success, 2 usage error, 3 not found, 4 auth error, 5 API error, 7 rate limited, 10 config error.

Health Check

mailchimp-pp-cli doctor

Verifies configuration, credentials, and connectivity to the API.

Configuration

Config file: ~/.config/mailchimp-marketing-pp-cli/config.toml

Static request headers can be configured under headers; per-command header overrides take precedence.

Environment variables:

Name	Kind	Required	Description
MAILCHIMP_API_KEY	per_call	Yes	Full Mailchimp API key with -dc suffix (e.g., abc...-us6). The CLI parses the suffix to route requests and sets HTTP Basic auth automatically.
MAILCHIMP_DC	per_call	No	Override datacenter (e.g., us6). Useful for OAuth tokens that lack the suffix. Takes precedence over the key's embedded -dc.
MAILCHIMP_USERNAME	per_call	No	Legacy: explicit Basic-auth username. Ignored when MAILCHIMP_API_KEY is set.
MAILCHIMP_PASSWORD	per_call	No	Legacy: explicit Basic-auth password. Ignored when MAILCHIMP_API_KEY is set.

Troubleshooting

Authentication errors (exit code 4)

• Run mailchimp-pp-cli doctor to check credentials
• Verify the environment variable is set: echo "${MAILCHIMP_API_KEY:0:8}…${MAILCHIMP_API_KEY: -4}" (avoid printing the full key) Not found errors (exit code 3)
• Check the resource ID is correct
• Run the list command to see available items

API-specific

• doctor reports 'no datacenter suffix in API key' — Mailchimp keys must end with '-us1' through '-us21'. Re-copy the key from https://us1.admin.mailchimp.com/account/api/; the dashboard truncates it visually.
• 429 'rate limit' on bulk operations — Mailchimp caps at 10 concurrent connections per key. For more than ~50 mutations, use 'mailchimp-pp-cli bulk-subscribe' which posts to /batches.
• 'Member Exists' error on creating a subscriber — Mailchimp uses PUT for upsert, not POST. The 'mailchimp-pp-cli subscribe' command handles this automatically; for raw API calls use the 'lists members upsert' subcommand (PUT) instead of 'create' (POST).
• Batch finished but result URL returns 404 — Mailchimp's response_body_url is valid only 10 minutes after batch completion. 'mailchimp-pp-cli bulk-subscribe --watch' polls and downloads within the window.
• doctor passes but every API call returns 401 — Mailchimp's HTTP Basic auth uses 'anystring:{KEY}'. If you exported MAILCHIMP_API_KEY with a leading space or quoted wrapper, strip them. The key starts immediately after '='.

Known Limitations

A few documented upstream behaviors that surprise CLI users:

• file-manager get-folders-id and get-folders-files return 200 with default content for invalid folder IDs. The Mailchimp API treats an unknown folder ID as "the unfiled bucket" and returns the empty default rather than 404. Check the id field in the response: an id: 0 with name: "Unfiled" indicates the folder did not match anything.
• sms-campaigns content get-sms-campaigns-id returns 200 with empty message_body for invalid campaign IDs rather than 404. Most other Mailchimp endpoints (e.g., campaigns get-id, lists get-id, account-exports get-id) return clean 404s.
• workflow archive --json emits NDJSON (newline-delimited JSON event stream), not a single JSON document. This is intentional for streaming sync events; pipe through jq -c or read line-by-line.
