# List email designs

> Lists the brand’s designs, newest first on the `sortBy` timestamp, as `{ data, pagination }`. Each row carries `emailId`, the latest `emailVersionId`, `title`, `status`, `previewImage` (when captured), `updatedAt`, `group` (`{ groupId, groupName }` or `null` when Ungrouped) and its creator.

**Use when** browsing designs or finding the `emailId` to send, edit or inspect. One design with its HTML or version history is `getEmail`.

**Input** `status` (`generating`, `ready`, `failed`), `groupId` (`grp_…` or `ungrouped`), `sortBy` (`updatedAt` default, or `createdAt`) with an inclusive `from`/`to` ISO 8601 window on that timestamp, `limit` and `cursor`.

**Returns** `200` with a page of `EmailSummary` rows and a `pagination` envelope (`cursor` is `null` on the last page). `createdBy` is the creator exactly as the Brew emails list shows it: a person’s name (`Former member` once they leave the brand), `API` or `MCP` for a credential with no person, or the two joined (`Name · MCP`); `createdByUserId` is that person’s stable user id. `createdBy` is absent when the creator cannot be named, with `createdByUserId` still present.

**Errors** `400 INVALID_REQUEST` for an unknown query key, an invalid status or a reversed window.

**See also** `getEmail`, `listEmailGroups`, `listTemplates` (the public gallery).

  title: Brew Public API v1
  version: 1.0.0
  description: >-
    Brew Public API v1. Generated from the app Zod contracts
    (`lib/<domain>/contracts.ts`): this document is the contract, and every
    operation documents exactly the error codes it can return.


    - Base URL `https://brew.new/api`; every path starts with `/v1`; JSON in and
    out. Request bodies and query strings are strict: an unknown key is `400
    INVALID_REQUEST` and `error.param` names it.

    - Identity is always in the path. `GET /v1/<collection>` lists (`{ data,
    pagination: { limit, cursor, hasMore } }`; page until `cursor` is `null`),
    and `GET /v1/<collection>/{id}` returns the bare resource, the same object a
    write returns. `?include=` expands relations on a detail read only, and is
    `400` on a list. There is no `?<idKey>=` read anywhere.

    - Writes carry identity in the path and return the bare resource: `POST
    /v1/<collection>` creates (`201`, or `202` when work continues
    asynchronously), `PATCH` and `DELETE /v1/<collection>/{id}` update or delete
    (`DELETE` answers `{ <idField>, deleted }` and is idempotent). Lifecycle
    state changes such as publishing ride `PATCH` as attributes. Two writes
    report more than the row and say so in their shape: `POST` and `PATCH
    /v1/contacts` are upserts that answer `{ contact, created | updated, … }`
    because whether a row was created, which fields changed, and which field
    definitions were minted are facts about the write, not about the contact.

    - Non-CRUD operations are explicit action sub-paths, for example `POST
    /v1/automations/{automationId}/test`, `POST /v1/domains/{domainId}/verify`,
    `POST /v1/sends/{sendId}/cancel` and `POST
    /v1/automations/triggers/{triggerEventId}/fire`.

    - Every resource has one root. Sends read and write at `/v1/sends`, fired
    triggers at `/v1/automations/trigger-instances`, and `/v1/analytics/*` holds
    only reports (aggregates over a window). Every endpoint answers in the same
    envelopes, with no exceptions.

    - Field names are camelCase; enum values are lowercase snake_case;
    timestamps are ISO 8601 UTC strings. Identifiers are opaque strings of at
    most 64 characters (`triggerEventId` up to 256); never parse a prefix.

    - Everything that runs shares one status vocabulary: `queued`, `scheduled`,
    `running`, `paused`, `completed`, `partially_completed`, `failed`,
    `canceled`. It covers sends, automation runs, manual audience runs, audience
    builds and inbox placement tests, so one status switch reads them all. A
    step inside a run is `running`, `completed`, `failed` or `skipped`.

    - Every error on every endpoint is `{ error: { code, type, message,
    suggestion, docs, param?, retryAfter?, details? } }`. Branch on `code`: the
    closed list is the `ApiErrorCode` component and every operation documents
    exactly the codes it can return. Non-fatal caveats arrive as `warnings: [{
    code, message, field? }]` on `2xx` bodies.

    - A credential is brand-scoped (the brand is implicit; send nothing) or
    organization-scoped (name the brand with the `X-Brand-Id` header on
    brand-scoped operations, else `400 BRAND_ID_REQUIRED`; there is no default
    brand). Only `POST /v1/api-keys` carries a `brandId` field, and only a
    signed-in organization admin session may call `/v1/api-keys`. A brand
    outside your reach surfaces as `404`, never `403`.

    - Send `Idempotency-Key` (up to 100 characters) on any POST you might
    repeat: the same key and body replays the original response for 24 hours;
    the same key with a different body is `409 IDEMPOTENCY_CONFLICT`. Rate
    limits are per credential and named policy (`X-RateLimit-*` headers; `429`
    carries `Retry-After`). Credit-metered operations advertise `402` and carry
    `x-brew-credited: true` in the spec.

    - Discovery without a key: `GET /v1/help` (JSON catalog with scopes, credits
    and rate limits per operation), `GET /v1/llms.txt` (this guide) and `GET
    /v1/health`. The OpenAPI document is served at `/openapi.json`.

      Email designs and sending. Generate a design with the Brew email agent,

        `updatedAt`, `group` (`{ groupId, groupName }` or `null` when Ungrouped)
        and its creator.


        **Use when** browsing designs or finding the `emailId` to send, edit or
        inspect. One design with its HTML or version history is `getEmail`.


        **Input** `status` (`generating`, `ready`, `failed`), `groupId` (`grp_…`
        or `ungrouped`), `sortBy` (`updatedAt` default, or `createdAt`) with an
        inclusive `from`/`to` ISO 8601 window on that timestamp, `limit` and
        `cursor`.


        **Returns** `200` with a page of `EmailSummary` rows and a `pagination`
        envelope (`cursor` is `null` on the last page). `createdBy` is the
        creator exactly as the Brew emails list shows it: a person’s name
        (`Former member` once they leave the brand), `API` or `MCP` for a
        credential with no person, or the two joined (`Name · MCP`);
        `createdByUserId` is that person’s stable user id. `createdBy` is absent
        when the creator cannot be named, with `createdByUserId` still present.


        **Errors** `400 INVALID_REQUEST` for an unknown query key, an invalid
        status or a reversed window.
