ZeptoMail

Choose a ZeptoMail live or sandbox agent and preserve its acknowledgment scope.

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

Configure the account

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

export const configuredZeptomailAccount = (apiKey: Redacted.Redacted) =>
  zeptomailEmailLayer({ apiKey, agentMode: "Live" }).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

  • agentMode describes the selected mail agent. Live and Sandbox produce different receipt meanings; the SDK does not toggle the remote agent.
  • Explicit MIME types, inline attachments and unique headers are supported. Metadata, tags and scheduling are unsupported.
  • Provider attachment extension restrictions still apply after common attachment validation.

Idempotency

The adapter declares no send key support. A sandbox acknowledgment is Simulated, not evidence of live acceptance or delivery.

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.
