Customer.io, BB (74.5)\n\nCustomer.io is a customer engagement platform that stores profiles and events, builds segments and sends automated email, SMS, push, in-app and WhatsApp messages. Agents reach it through REST APIs, a hosted MCP server and a command-line tool. The hosted MCP server uses OAuth with five scopes, starts read-only, and keeps live sends and sensitive attributes behind admin settings that are off by default. The App API allows 10 requests a second and no idempotency keys were found for sends. No SLA is published, and the status page lists 11 incidents in 90 days.\n\n- Page: https://www.anchorterminal.com/tools/customer-io · Markdown: https://www.anchorterminal.com/tools/customer-io.md · JSON: https://www.anchorterminal.com/api/v1/tools/customer-io.json\n- Capabilities: marketing.profiles, marketing.events, marketing.segments, marketing.campaigns, marketing.journeys, email.send, email.templates, messaging.sms, notify.push, notify.in-app · endpoint: `https://mcp.customer.io/mcp`\n\n### 98. Klaviyo API + MCP, BB (71.7)\n\nKlaviyo is a marketing platform that holds customer profiles and events and sends email, SMS, WhatsApp and push campaigns and flows. Agents reach it through a JSON:API REST API and an official hosted MCP server. The REST API has a public OpenAPI 3 description of 345 operations, scoped keys and OAuth, and dated revisions supported for two years. The hosted MCP server lists 274 tools with a read-only switch. No approval step before a campaign send was found in the reviewed documentation, and no SLA is published.\n\n- Page: https://www.anchorterminal.com/tools/klaviyo · Markdown: https://www.anchorterminal.com/tools/klaviyo.md · JSON: https://www.anchorterminal.com/api/v1/tools/klaviyo.json\n- Capabilities: marketing.profiles, marketing.events, marketing.segments, marketing.campaigns, marketing.journeys, email.templates · endpoint: `https://a.klaviyo.com`\n\n### 330. Braze, C (61.2)\n\nBraze is a hosted engagement platform that stores customer profiles and events, builds segments and sends campaigns and Canvas journeys by email, SMS, push and in-app message. Agents reach it through a REST API and an official remote MCP server. The REST API covers profiles, events, sends and exports with keys limited to named endpoints, and the remote MCP server adds 71 tools under OAuth with PKCE that return no user-level personal data. No OpenAPI document, idempotency keys, published price or SLA were found, and MCP writes run without a confirmation step.\n\n- Page: https://www.anchorterminal.com/tools/braze · Markdown: https://www.anchorterminal.com/tools/braze.md · JSON: https://www.anchorterminal.com/api/v1/tools/braze.json\n- Capabilities: marketing.profiles, marketing.events, marketing.campaigns, marketing.journeys, marketing.segments · endpoint: `https://mcp.braze.com/mcp`\n\n### 457. Iterable, C (55.2)\n\nIterable is a hosted customer engagement platform that stores user profiles and events and sends campaigns and journeys by email, SMS, push, in-app and WhatsApp. Agents reach it through a REST API and an official local MCP server, in beta. The REST API publishes a Swagger 2.0 contract with 159 operations, typed API keys including a read-only type, and per-endpoint rate limits. 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- Page: https://www.anchorterminal.com/tools/iterable · Markdown: https://www.anchorterminal.com/tools/iterable.md · JSON: https://www.anchorterminal.com/api/v1/tools/iterable.json\n- Capabilities: marketing.profiles, marketing.events, marketing.segments, marketing.campaigns, marketing.journeys, email.templates · endpoint: `https://api.iterable.com`\n\n### 516. ActiveCampaign, D (50.5)\n\nActiveCampaign is a hosted marketing automation platform for email, SMS and WhatsApp with a built-in CRM.

Each user has one unscoped API key, the limit is 5 requests a second, and no changelog was found. The status page shows three critical incidents between 27 July and 28 September 2026.\n\n- Page: https://www.anchorterminal.com/tools/activecampaign · Markdown: https://www.anchorterminal.com/tools/activecampaign.md · JSON: https://www.anchorterminal.com/api/v1/tools/activecampaign.json\n- Capabilities: marketing.profiles, marketing.events, marketing.segments, marketing.campaigns, marketing.journeys, crm.records, crm.pipeline, crm.webhooks, messaging.sms, messaging.whatsapp\n\n## How we test this category\n\nThe same hundred test profiles and events loaded into each listing. The same tasks run through its API (update a profile, track an event, build a segment, trigger a message, read campaign results). We check rate limits, consent handling and how a send is held for approval. In this run listings are graded from public evidence against the published checklist. This test hasn't run yet, so Task success is pending and the grades here come from the categories assessed from public evidence.\n\n",
