The 8 October incident reading came from the page's JSON API, which its robots.txt closes, so it is struck and the window was re-read from /history.atom on 4 November. The 90 days from 6 August hold four incidents, each partial by its own text, Twilio SMS drops for a subset of customers on 1 September, EU platform slowness and gateway errors on 10 September (about 9:25 to 11:13 EDT), timeouts on the user update endpoints on 22 September, and delayed sends for some SparkPost US customers on 28 October. The 16 July critical incident has left the window. Minor only (20, from 15). 53 of 159 operations state a numeric limit in the specification re-read on 4 November (15). Only 7 operations document 429, two of them with `rateLimitReset` in the body. No Retry-After header or idempotency key was found in the specification, and backoff guidance on the support centre couldn't be read (6, an earlier partial kept). No SLA was found in the Master Services Agreement (last updated 8 June 2026) or the product-specific terms (0). The REST API is generally available. The MCP server is beta (10). 20+20+15+6+0+10 = 71.\n- Sequenzy (38): Graded with the hosted lines. No status page was found; none is linked from the site, llms.txt or docs, and status.sequenzy.com doesn't resolve (0). With no history to read, the incident line takes 5. 429 responses carry RateLimit-Limit and RateLimit-Remaining headers for a per-minute policy, and some routes state numbers (20 requests a minute per workspace for AI copy), but no table of limits per key was found (8 of 15). 429s carry Retry-After, sends take an `Idempotency-Key`, a reused key with a different body returns IDEMPOTENCY_KEY_REUSED, and the MCP docs say a retry hint alone doesn't make a write safe to repeat (15). No SLA found (0). No beta label on the API or MCP server (10). Total 38.\n\n### Schema \u0026 documentation: Sequenzy +30\n\n- Iterable (65): Public Swagger 2.0 specification at api.iterable.com/api-docs, which the API explorer page links as 'Raw API specification (JSON)', with 159 operations and 209 schemas on 4 November (25). iterable.com/llms.txt exists but describes the company and links the documentation without carrying it, and no Markdown docs were found (4). All 159 operations have a summary and 147 a description, several with cautions such as the 60-second wait after a user update and the suppression list rule on campaign creation (14). Required fields are marked and there are 35 enums, while `dataFields` and template content stay free-form objects (11). The specification has 21 examples. 400 and 401 appear on nearly every operation, and the error body has a 26-value `code` enum (8). The specification is labelled version 1.8 with no version in the path. Release notes sit on the support centre, which answered a Cloudflare check again on 4 November, so only 3 of 15 here (an earlier partial kept). The specification was re-read on 4 November, and the description, enum and example counts are per the 8 October check. 25+4+14+11+8+3 = 65.\n- Sequenzy (95): OpenAPI 3.1 at docs.sequenzy.com/openapi.yaml with 349 paths and 475 operations, all described (25). llms.txt on both hosts, llms-full.txt, auth.md, agents.md and Markdown twins of the docs (10). Operation and tool descriptions give purpose, the scope each needs and the alternative, such as the deprecated generate-sequence alias (18 of 20). Typed inputs, and tools reject undeclared arguments with an error naming the supported ones (13 of 15). Errors on nearly every operation (401 on 442, 404 on 330, 400 on 290) with examples, and a structured error with code, `howToFix` and `docsUrl` for tools (14 of 15). Version in the path and spec, and a dated changelog (15). Total 95.\n\n### Agent ergonomics: Sequenzy +12\n\n- Iterable (57): API list calls take `page` and `pageSize`, and the MCP server shows 31 of its 118 tools by default, with three flags that add the rest (15). `nextPageUrl` paging on campaigns, catalogues, journeys and templates, state and sort filters on campaigns, and `limit` on events, but list member reads are capped at 5 requests a minute (14). Errors carry a `code` from a 26-value enum, a message and `params`, with reset seconds on some 429s (15). No idempotency keys. User updates merge and catalogue PUT replaces, so those retries are safe, but sends aren't. The MCP tools have no readOnlyHint or destructiveHint, and an issue asking for them has been open since 4 June 2026 (6). Most calls need few parameters. The one server-side SDK is the TypeScript client, which its README calls experimental (7). Per the 8 October check, and the MCP repository has no commit since 1.9.0 on 30 September. 15+14+15+6+7 = 57.\n- Sequenzy (69): The MCP tool reference lists about 306 tools, the over-30 band, and no toolsets, tool search or dynamic loading was found (5 of 25). List endpoints paginate and filter, and contact timelines use cursors (20). Errors carry a code, a human message, a fix and a docs link, with `retryAfterSeconds` when the API sent Retry-After (20). Idempotency keys on sends and event imports; MCP readOnlyHint and destructiveHint annotations weren't found in the published reference (14 of 20). Sensible defaults with a selected workspace; one official SDK (TypeScript) plus a CLI (10 of 15). Total 69.\n\n### Security \u0026 auth: Sequenzy +12\n\n- Iterable (55): API keys come in five types and each operation lists the types it accepts. A read-only type works on 30 operations, and the key travels only in a header. Rotation and expiry are unchecked because the key guide couldn't be read (22). The read-only key type, and an MCP server that starts with PII, writes and sends all off and stores those settings per key. Neither surface has a confirmation step, and the README leaves review of each call to the person (16). Profiles, events and templates hold customer-written text. The README warns about irreversible actions but gives no injection guidance (3). No audit log or per-call record for the operator was found in the pages we could read (0). The responsible disclosure policy, re-read on 4 November, says Iterable responds 'usually one to three business days' and that there is no public bug bounty. No security.txt, SOC 2 Type 2, ISO 27001 and HIPAA on the trust centre, and CodeQL on the open repositories (14). 22+16+3+0+14 = 55.\n- Sequenzy (67): Workspace and account API keys with fine-grained permission scopes, presets and explicit `*:delete` rights, revocable in settings, plus an OAuth `service_auth` flow for agents with user confirmation (30). Read-only and drafts-only presets let an agent prepare mail without sending, and account keys keep the user's workspace role (20). The agent inbox and reply tracking give the agent inbound mail, and no prompt-injection guidance was found in the MCP, permissions or inbox docs (4 of 15). The DPA lists administrative audit logs and MCP events report replies and bounces; no per-call API log for the customer was found (8 of 15). A responsible disclosure address on the security page, no security.txt (404), bug bounty or certification (5 of 20).

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, answers automated readers with a bot check.\n\n**Sequenzy.** Scoped keys with read-only and drafts-only presets, a 475-operation OpenAPI spec, idempotent sends and near-daily dated releases make it workable for an agent. The MCP server lists about 306 tools, which is heavy on context, and there is no status page, SLA or published request limit table.\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### Sequenzy\n\n1. Connect with a drafts-only or read-only key unless the task must send, and widen permissions only when an error names the missing scope\n2. Send an `Idempotency-Key` with each transactional send and reuse it unchanged after an uncertain result\n3. Read `structuredContent.error.code` and `howToFix` on a failed tool call before retrying; the client doesn't retry\n4. Call `get_account` and `select_company` first when the key can reach more than one workspace\n5. On 429 wait for Retry-After and read the RateLimit-Remaining header\n\n## Questions\n\n### Which is better for AI agents, Iterable or Sequenzy?\n\nSequenzy scores 63.7 (B) on agent readiness against Iterable's 56.3 (C), and leads in 5 of 7 scored categories. Iterable leads on reliability.\n\n### Do Iterable and Sequenzy need an API key?\n\nIterable needs an API key. Sequenzy takes an API key or an OAuth sign-in.\n\n### Can an agent call Iterable and Sequenzy without installing anything?\n\nYes.
