### Guide: How to Configure DMARC (CNAME)

Congratulations on successfully adding your domain! The next step is to create a CNAME record in your domain's DNS settings. Since the process varies depending on your domain hosting service, here is a general overview:

#### 1. Log Into Your Hosting Account

Access the control panel of your domain hosting service.

#### 2. Find DNS Settings

Look for the DNS management section (e.g., 'DNS Settings', 'Name Server Management').

#### 3. Add a CNAME Record

Locate the option to add a new DNS record, selecting 'CNAME' as the record type.

#### 4. Configure the CNAME Record

Set Name/Alias to desired subdomain (e.g. _dmarc). Set Type to CNAME. Set Target/Points to the destination address.

#### 5. Save Your Changes

Complete the process by saving the new record.

#### 6. Wait for Propagation

DNS updates can take up to 48 hours to propagate across the internet.

#### Example CNAME Record Details:

| Type  | Name    | TTL              | Value                                      |
|-------|---------|------------------|--------------------------------------------|
| CNAME | _dmarc  | 1 hour (or default) | sd_ptcfi6970b5c9e5958.securedmarc.com   |

* The value above is an example. Use the specific value from your dashboard.

### Setting up SPF

SPF setup typically involves adding a TXT record to your DNS. SimpleDMARC handles flattening automatically. In your dashboard, copy the provided SPF include mechanism and add it to your existing SPF record or create a new one if none exists.

### Configuring DKIM

DKIM requires generating a private/public key pair. SimpleDMARC generates these for you. You simply need to add the provided CNAME or TXT records to your DNS to publish the public key.

### BIMI Implementation

BIMI requires DMARC at enforcement (p=reject or p=quarantine) and a verified mark certificate (VMC) for some providers. Upload your SVG logo in the dashboard and we will guide you through the VMC process.
