On Resend email failed - Automate.ax

resend.onEmailFailed handles email.failed, a send failure rather than a recipient-server bounce.

automations/handle-resend-failure.automation.ts

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

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

Optional static account selects the binding.

Trigger data

Returns the shared Resend outbound event fields, plus failure details:

type ResendEmailFailedEvent = ResendOutboundEvent<"email.failed"> & {
  failed: { reason: string }
}

event preserves the original Resend envelope.
