# Custom Sender Domain

Send auction emails from your own domain instead of the default Auction Plus address. This gives your emails a professional, branded appearance.

> **Note:** Custom sender domains are available on the **Grow plan and above**. See [Plans](https://admin.shopify.com/apps/auction-plus/plans) for details on upgrading.

## Why Use a Custom Sender Domain?

* **Professional branding** — Emails come from an address like `auctions@yourdomain.com` instead of a generic address
* **Consistent customer experience** — Your customers see your brand at every touchpoint

## Setup Steps

### 1. Enter Your Custom Email Address

1. Open **Settings > Notifications**
2. In the **Email** section, update **Sender Email**
3. Enter your desired sender email address (e.g., `auctions@yourdomain.com`)

### 2. Add DNS Records

You will need to add two DNS records to your domain. Auction Plus will provide the exact values for each record.

**DKIM Record:**

* Type: TXT
* Add this record to your domain's DNS settings
* This authenticates your emails and prevents spoofing

**Return Path Record:**

* Type: CNAME
* Add this record to your domain's DNS settings
* This ensures bounced emails are handled correctly

> **Tip:** If you are unsure how to add DNS records, check your domain registrar's help documentation. You can typically add DNS records through the account where you registered your domain.

### 3. Verify Your Domain

1. After adding the DNS records, return to **Settings > Notifications**
2. Click **Verify DNS Records**
3. Auction Plus will check that your DNS records are correctly configured
4. Once verified, all outgoing emails will be sent from your custom address

> **Note:** DNS changes typically take effect within a few hours, but can take up to 48 hours to fully propagate. If verification fails, wait and try again later.
