pp-mailchimp
Every Mailchimp endpoint plus the workflow commands the API forces you to compose yourself. Trigger phrases: `subscribe to mailchimp`, `add a contact to mailchimp`, `send a mailchimp campaign`, `mailchimp campaign performance`, `import contacts to mailchimp`, `audit mailchimp segments`, `mailchimp deliverability`, `use mailchimp`, `run mailchimp`.
Why this skill is useful
Adds a CLI tool that automates complex Mailchimp workflows and provides unique commands for batch processing and reporting that aren't available in the standard API.
What it needs
Requires mailchimp-pp-cli installed locally. About 10k tokens when loaded. Last updated 2026-08-06. 1,890 stars on the source repository.
What this skill does
Mailchimp — Printing Press CLI Prerequisites: Install the CLI This skill drives the mailchimp-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows: 2. Verify: mailchimp-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill. If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer): If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds. When to Use This CLI Reach for this CLI when you need to drive Mailchimp from a terminal or agent and the workflow spans more than one endpoint: subscribing a contact with tags, importing a CSV through the batch endpoint, measuring whether a campaign worked, or auditing segment hygiene. The local SQLite cache makes the audience SQL-queryable, which is impossible through the dashboard or the SDK. The MCP surface uses code orchestration over 291 endpoints in ~1K tokens, so an agent can reach any Mailchimp endpoint without bloating its tool list. Unique Capabilities 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. 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. …
