Breadth is the point: campaigns, audiences, members, segments, automations, reports, landing pages, e-commerce, surveys, signup forms and verified domains, with multi-account support. Breadth is also the risk, which is why the runtime guardrails matter more than the tool count. Every tool carries risk metadata, and the server can be started read-only, in dry-run, or with an audit log, so exploration and sending are separate decisions rather than one accident. It calls the marketing API over plain HTTP instead of the official Python client, a deliberate choice by the author after hitting problems with it. Note that a Mailchimp key ends in a datacentre suffix and the server expects it intact.
