AI-native email infrastructure

Email that
thinks for itself.

IMBOX is the email platform built for the AI era. A developer-first API, a beautiful webmail, and an intelligent agent — all in one. Send at scale. Read with context. Act without asking.

send-email.ts
const res = await fetch('/api/v1/emails/send', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer sk_live_...'
  },
  body: JSON.stringify({
    to: [{ address: 'hello@acme.com' }],
    subject: 'Welcome aboard',
    template_id: 'welcome-v2'
  })
})

Three products. One platform.

Everything you need to own your email infrastructure.

Email API

Resend-grade REST API. Send transactional emails, manage mailboxes, search messages, track delivery — all with one API key. Templates, webhooks, batch sending included.

Webmail

Beautiful, fast, tenant-scoped. Your users get a full-featured webmail — compose, reply, search, filters, folders — without you building a single UI component.
