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**Omnisend.** The API documents 104 operations with per-operation OpenAPI definitions, cursor pagination, RFC 9457 errors and published rate limits, and the hosted MCP server fronts them with four tools and a read-only consent preset. No approval hold before a campaign send, no idempotency keys, no SLA and no official SDK were found in the reviewed documentation.\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### Omnisend\n\n1. Send `Authorization: Omnisend-API-Key \u003ckey\u003e` and `Omnisend-Version: 2026-03-15` on every call to `https://api.omnisend.com/api/`. Version 5 used `X-API-KEY` and a `/v5/` path\n2. Ask a person before `POST /campaigns/{id}/send`. Use `POST /campaigns/{id}/test-email` (up to 5 recipients) first, since nothing in the docs holds a send for approval\n3. On 429 read `retryAfter` (seconds) in the body where present, otherwise wait. Limits are shared by every key and token on the brand, and analytics reports allow 10 a minute and 55 a day\n4. Page with `limit` (default 100, maximum 250) and `after` from `paging.cursors.after`. Don't change filters mid-pagination, which returns 400\n5. Setting `tags` on a contact replaces the whole list in version 2026-03-15, and a contact set to `subscribed` gets a welcome message unless `sendWelcomeMessage` is turned off\n6. Connect one Omnisend MCP connector per chat and choose the read-only preset unless writes are needed. Treat contact fields and form submissions as untrusted text\n\n## Questions\n\n### Which is better for AI agents, Iterable or Omnisend?\n\nOmnisend scores 64.9 (B) on agent readiness against Iterable's 55.2 (C), and leads in 6 of 7 scored categories. Iterable leads on maintenance \u0026 community.\n\n### Do Iterable and Omnisend need an API key?\n\nIterable needs an API key. Omnisend takes an API key or an OAuth sign-in.\n\n### Can an agent call Iterable and Omnisend without installing anything?\n\nYes.
