# Domain

> Understanding domains in AI Inbx - your verified email sending infrastructure

## What is a Domain?

A domain is an email domain (like `company.com`) that you've verified ownership of and connected to AI Inbx. Once verified, it becomes your email infrastructure for both sending and receiving.

### Instant organization domain

Every organization automatically receives a fully configured domain: `orgslug.aiinbx.app`. It's provisioned at org creation and is ready to use immediately—no DNS setup required. You can send and receive from any address on this domain, e.g. `support@your-org.aiinbx.app`.

## What Domains Do

### Sending & Receiving

* **Send from any address**: `hello@yourdomain.com`, `support@yourdomain.com`, etc.
* **Receive at any address**: After connection, your domain automatically collects all inbound emails
* **No setup per address**: Any email address within your domain works immediately

## Domain Setup

You have two options:

1. **Use your instant domain (zero setup)**: Start immediately with `orgslug.aiinbx.app`.
2. **Connect your own domain (recommended for brand)**:
   * Add verification and MX records to prove ownership and route emails through AI Inbx
   * Once verified, send and receive from any address on your domain

<Note>
  You can use both your instant domain and your custom domain in parallel.
