# Mailchimp **Canonical:** https://apis.io/providers/mailchimp/ **Website:** https://mailchimp.com/developer/ **APIs profiled:** 120 Mailchimp is an Intuit company providing a marketing automation platform and email marketing service for managing mailing lists, creating email marketing campaigns, and automating marketing workflows. It exposes two distinct developer surfaces: the Marketing API (v3, REST, 298 operations at https://.api.mailchimp.com/3.0) covering audiences, members, tags, segments, campaigns, content, automations, customer journeys, reports, e-commerce stores and orders, file manager, templates, landing pages, batch operations and webhooks; and Mailchimp Transactional, formerly Mandrill (99 RPC-style POST methods at https://mandrillapp.com/api/1.0), for one-to-one transactional email and SMS, inbound processing, dedicated IP management and subaccounts. Authentication is an API key or OAuth 2 for the Marketing API and a body-parameter API key for Transactional. Mailchimp runs a hosted MCP server for the Transactional API, publishes eight official client libraries and two mobile SDKs, and delivers audience events as HMAC-signed webhooks. ## Kin Score — 81.6 / 100 (exemplar) Scored 2026-08-20 under rubric 0.12.0.
