Verify your domain so the system can send emails to your customers from your own addresses, such as support@ or accounts@ your domain. DKIM verification protects your emails from being marked as spam and builds trust in your brand.

## Before you start

- You need access to your domain's DNS settings, or someone who has it, such as your domain provider or IT administrator.

## 1. Add your domain

1. Sign in to the partner portal as an administrator.
2. Go to **Settings** › **Email configuration**.
3. Under **Domains**, click **New domain**.
4. Enter your domain name without www or https, for example `example.com`, and click **Add**.

The system creates the DNS records you need. They're shown in the domain's row: three CNAME records for sending and DKIM signing (**CNAME1**, **CNAME2**, **CNAME3**) and an optional DMARC record (**TXT**). Each shows a **HOST**, a **VALUE** and a **STATUS**.

## 2. Add the records to your DNS

1. Copy each record from the portal.
2. Add them to your domain's DNS settings, exactly as shown.

## 3. Verify the domain

1. Return to **Settings** › **Email configuration**.
2. Select your domain and click **Verify**.

Each CNAME record's **STATUS** changes from **Not verified** to **Verified** once the DNS record is found. The **TXT** record always shows **STATUS: optional**.

DNS changes can take up to 48 hours to spread. If verification fails, wait and try again.

## 4. Choose your sending addresses

1. At the top of **Email configuration**, set the **Local part** and **Domain** for each address: **Support email**, **Info email**, **No-reply email**, **Accounts email**, **LNP (number porting) updates email**, **Sales email** and **PBX email**. **Domain** lists only domains whose three CNAME records are verified.
2. Click **Update**.

## Check it works

- **CNAME1**, **CNAME2** and **CNAME3** all show **STATUS: Verified** in the **Domains** list.
- Trigger an email to a test customer, such as a password reset, and check that it comes from your address and arrives in the inbox.
