The MCP server starts read-only, with PII, writes and sends each switched on separately. No price, trial or self-serve signup is published, and the support centre, which holds the API guides, refused automated readers.\n\n**Mailchimp Marketing API.** A public OpenAPI 3.1 file covers all 297 operations, every docs page has a Markdown copy, and responses can be trimmed with `fields`. An API key carries full account access with no read-only option. The quick start's TypeScript package was not on npm on 8 October 2026, and the changelog's newest entry is 19 August 2025.\n\n## Before you call either\n\n### Iterable\n\n1. Send the key in the `Api-Key` header, and use api.eu.iterable.com for projects in the EU data centre\n2. Wait at least 60 seconds after `POST /api/users/update` before a dependent call such as `POST /api/email/target`, as the specification advises\n3. Keep the MCP server on its default read-only setup unless a person reviews each call. Writes and sends act on real users and can't be undone\n4. Pass `suppressionListIds` to `POST /api/campaigns/create`. Global suppression lists aren't added automatically\n5. Read `rateLimitReset` in the 429 `params` on user update calls for the seconds to wait. List member reads allow 5 requests a minute per project\n\n### Mailchimp Marketing API\n\n1. Send the key or OAuth token as `Authorization: Bearer` to `https://api.mailchimp.com/3.0/`. Treat it as full account access and keep it server-side\n2. Address a contact by the MD5 hash of the lowercase email address, and use PUT on `/lists/{list_id}/members/{subscriber_hash}` so a retry does not create a duplicate\n3. Ask a person before POST `/campaigns/{campaign_id}/actions/send`. Read `/campaigns/{campaign_id}/send-checklist` and use `actions/test` first\n4. Keep to 10 concurrent requests per user, and send large jobs to `/batches`. A 429 names no wait time, so back off and retry\n5. Add `fields=` to every list call and set `count` (default 10, maximum 1,000) with `offset`\n6. Set `is_syncing` to true when loading historical events so they do not trigger automations\n\n## Questions\n\n### Which is better for AI agents, Iterable or Mailchimp Marketing API?\n\nMailchimp Marketing API scores 57.4 (C) on agent readiness against Iterable's 55.2 (C), and leads in 4 of 7 scored categories. Iterable leads on reliability, security \u0026 auth and maintenance \u0026 community.\n\n### Do Iterable and Mailchimp Marketing API need an API key?\n\nIterable needs an API key. Mailchimp Marketing API takes an API key or an OAuth sign-in.\n\n### Can an agent call Iterable and Mailchimp Marketing API without installing anything?\n\nYes.
