Eight 'multiple services' full outages on the status page since July.\n\n**Mailchimp Transactional (Mandrill).** A public OpenAPI 3.1 file covers all 99 operations, the docs serve Markdown and llms.txt, and keys can be limited by endpoint and IP address. Sending needs a Standard or Premium Mailchimp plan plus $20 blocks of 25,000 emails. No send idempotency key or SLA was found, and the newest dated release is from 24 March 2026.\n\n## Before you call either\n\n### Brevo API + MCP\n\n1. Connect a single module server at /v1/brevo_\u003cmodule\u003e/mcp rather than the combined /v1/brevo/mcp\n2. Send with POST /v3/smtp/email and the `api-key` header, not Bearer\n3. Use webhooks for delivery events. GET /v3/smtp/emails allows 2 requests a second\n4. Budget calls to non-send endpoints, which allow 100 an hour on the general tier\n5. Wait for account approval before counting on the free plan's 300 a day\n\n### Mailchimp Transactional (Mandrill)\n\n1. Send every call as POST with the key in the JSON body as `key`. The MCP server takes the same key as `Authorization: Bearer`\n2. Use a test API key while building. Test sends are free, capped at 10,000 a day, and deliver nothing\n3. Verify the sending domain with DKIM and DMARC first. Mail from an unverified domain is rejected with the reason `unsigned`\n4. Keep `/messages/search` under 20 calls a minute and set `limit` (default 100, maximum 1,000). There is no offset, so use an activity export for more\n5. For a restricted key that must also use the MCP server, enable the AI Agents permission group on the key\n\n## Questions\n\n### Which is better for AI agents, Brevo API + MCP or Mailchimp Transactional (Mandrill)?\n\nMailchimp Transactional (Mandrill) scores 58.1 (C) on agent readiness against Brevo API + MCP's 44.8 (E), and leads in 3 of 7 scored categories.
