# Subdomains

> Send each kind of email from its own subdomain of a verified domain

<Badge color="green">New</Badge>

A subdomain such as `news.example.com` sends email under its own name, so
marketing mail never affects the reputation of mail sent from `example.com`.
Manage subdomains from the **Subdomains** tab on a domain's detail page.

## Prerequisites

* A domain you have [verified](/user-guide/domains/verify) or
  [registered](/user-guide/domains/register) with Bizzy. A subdomain belongs to
  that domain, so you don't verify it separately.

## Purposes

Each subdomain has a purpose. It decides what the subdomain does and which
[email addresses](/user-guide/email-addresses/bizzy-hosted) can use it.

| Purpose | What it does | Addresses that can use it |
| - | - | - |
| **General** | Sends and receives email | General and transactional |
| **Transactional** | Sends receipts, invoices and notifications only | Transactional |
| **Marketing** | Sends newsletters and campaigns only | Marketing |

Transactional and marketing subdomains don't receive mail, so they never
conflict with a mail host such as Google Workspace or Microsoft 365 that already
serves your domain. A marketing email address can only use a marketing
subdomain.

## Adding a subdomain

1. Go to **Domains**, open the domain, and select the **Subdomains** tab.
2. Click **Add subdomain**.
3. Enter the **Name** — the part before your domain, such as `news`.
4. Choose a **Purpose**.
5. Click **Add subdomain**.

The subdomain appears in the list with the email status **Not Configured**. A
subdomain can't have subdomains of its own, so its detail page has no
**Subdomains** tab.

## Enabling email

Click **Enable email** on the subdomain's row. The status moves to **Setting
Up**, then to **Active** once the subdomain's records verify.

* **Registered through Bizzy** — the records are added for you.
* **Verified (DNS hosted elsewhere)** — open the subdomain, select **Settings**,
  and add the records listed there at your DNS host. See
  [Email deliverability](/user-guide/domains/deliverability).

If setup fails, click **Retry email setup** on the row.

## Deleting a subdomain

Click the delete icon on the subdomain's row, then confirm. Its email setup is
removed; the parent domain is unaffected. Delete a domain's subdomains before
you delete the domain itself.
