@rakun-kit/resend

Resend adapter for Rakun mail.

bun add @rakun-kit/resend

import { rakunBootstrap } from '@rakun-kit/core'
import { createResendMailServiceConfig } from '@rakun-kit/resend'

rakunBootstrap({
  // ...
  mail: createResendMailServiceConfig({
    apiKey: process.env.RESEND_API_KEY!,
    defaultFrom: {
      name: 'Rakun',
      address: '[email protected]',
    },
    defaultReplyTo: '[email protected]',
  }),
})

The adapter always receives already-rendered HTML/text from Rakun. Resend's hosted templates and react input are intentionally not exposed, keeping application templates portable between providers.

The sender domain used by defaultFrom must be verified in Resend. API errors are passed to the core service and wrapped as MailErrorSendFailed.
