Scaleway

Configure a Scaleway project with constrained transactional message support.

Import scalewayEmailLayer from @corven/email-sdk/scaleway to provide the common Email service for this account.

Configure the account

import { Layer } from "effect";
import type { Redacted } from "effect";
import { scalewayEmailLayer } from "@corven/email-sdk/scaleway";
import { emailHttpLayer } from "./sending.js";

export const configuredScalewayAccount = (secretKey: Redacted.Redacted) =>
  scalewayEmailLayer({
    secretKey,
    projectId: "00000000-0000-4000-8000-000000000001",
    tracking: "ProviderDisabled",
  }).pipe(Layer.provide(emailHttpLayer));

The example reuses the explicit HTTP Layer. Acquire credentials in trusted host code, then provide this account Layer to your sending program.

Message behavior

• Use a UUID projectId and a Redacted secretKey. tracking attests that provider tracking is disabled.
• Attachments require explicit supported MIME types; inline placement, common metadata, tags and scheduling are unsupported.
• Content and mailbox intent pass additional provider rules. Use the acquired service for final local validation.
• Receipts preserve recipient outcomes and provider correlation instead of collapsing them to one sent flag.

Idempotency

Idempotency keys are not supported. The SDK does not retry requests with unknown submission outcomes.

Read field support before switching accounts, and receipts and retries before adding recovery behavior. Configuration and local validation do not authenticate the account or prove delivery.
