description: Configure JetEmail transactional credentials, domain settings and idempotency key forwarding.

Import `jetemailEmailLayer` from `@corven/email-sdk/jetemail` to provide the common `Email` service for this account.

## Configure the account

```ts
import { Layer } from "effect";
import type { Redacted } from "effect";
import { jetemailEmailLayer } from "@corven/email-sdk/jetemail";
import { emailHttpLayer } from "./sending.js";

export const configuredJetemailAccount = (apiKey: Redacted.Redacted) =>
  jetemailEmailLayer({
    apiKey,
    automaticBcc: "DomainDisabled",
    tracking: "DomainDisabled",
    deliveryRegion: "ProviderSelected",
  }).pipe(Layer.provide(emailHttpLayer));
```

The example reuses the [explicit HTTP Layer](/sending#configure-transport-behavior). Acquire credentials in trusted host code, then provide this account Layer to your sending program.

## Message behavior

- Use a transactional_ submission token. Attest that domain automatic BCC and tracking are disabled before supplying these options.
- The sender requires an explicit display name; to recipients use plain mailboxes. Scheduled instants require whole seconds.
- Attachments use ProviderSelected MIME selection. Inline attachments, common metadata and tags are unsupported.
- deliveryRegion may be ProviderSelected or Europe; it does not establish cross-account deduplication.

## Idempotency

The adapter forwards keys of up to 256 characters. Its idempotency declaration is `KeyForwarding`. The SDK does not retry requests with unknown submission outcomes.

Read [field support](/providers/field-support) before switching accounts, and [receipts and retries](/reliability) before adding recovery behavior. Configuration and local validation do not authenticate the account or prove delivery.
