Every import path of @effect-kit/emails and what each one exports.

Source: https://effectkit.dev/docs/emails/reference/entry-points

`@effect-kit/emails` is ESM only and needs Node.js 24.22.0 or later. The root, `testing` and `react` entry points never import a provider. Each provider has its own subpath, so an SDK you do not use is never loaded.

`Email.sendMany` and `Email.make` are static members of `Email`.

## `@effect-kit/emails/testing` [#effect-kitemailstesting]

`EmailTest`, and the types `EmailTestOptions` and `EmailTestService`. See [Testing](/docs/emails/testing).

## `@effect-kit/emails/react` [#effect-kitemailsreact]

`render`, `RenderError`, `RenderOptions`, and the types `HtmlContent`, `TextContent`, `HtmlAndTextContent` and `RenderedContent`. Rendering needs `@react-email/render`, `react` and `react-dom`.

## Provider subpaths [#provider-subpaths]

Every provider exports `layer`, `layerClient` and `layerConfig`, plus types for its options and client. The Layers are in [Layers and environment variables](/docs/emails/reference/layers).

Importing a provider subpath without its SDK installed fails with `ERR_MODULE_NOT_FOUND`. The root and `testing` still import.
