On Resend email failed

onResendEmailFailed emits email.failed when Resend cannot send a message. This differs from a recipient-server bounce that happens during delivery.

automations/handle-resend-failure.automation.ts

import { automation } from "automate.ax"
import { onResendEmailFailed } from "automate.ax/resend"

export default automation("Handle Resend failures", () => {
  const failed = onResendEmailFailed()
  failed.transform(({ createdAt, data }) => ({
    createdAt,
    emailId: data.email_id,
    reason: data.failed,
  }))
})

Optional static account selects the binding. Returns { type: "email.failed"; createdAt: string; data: Record<string, JsonValue> }. Failure details remain in provider-native data and may vary by failure reason.
