How to Implement a DMARC Record in Google Domains

In today’s digital landscape, email security is more critical than ever. Implementing a DMARC (Domain-based Message Authentication, Reporting, and Conformance) record helps protect your domain from email spoofing and phishing attacks. If you’re using tools like Ubico to manage your outreach, a secure domain ensures that your campaigns reach the right audience without compromising trust.

What is a DMARC Record?

A DMARC record is a TXT record added to your domain’s DNS settings. It works alongside SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to authenticate your emails and provide instructions for handling messages that fail these checks. With DMARC, you can also receive detailed reports on email activity related to your domain.

Step-by-Step Guide to Adding a DMARC Record in Google Domains

Step 1: Log in to Google Domains

To get started, visit Google Domains and sign in with your Google account credentials.

Step 2: Select Your Domain

Once logged in, locate the domain where you want to add the DMARC record. Click on the domain name (e.g., ubico.io) to access its management settings.

Step 3: Access DNS Settings

In the left-hand menu, select DNS to open your domain’s DNS configuration page.

Step 4: Add a New TXT Record

Scroll down to the Custom Records section and click Manage custom records to open the editor.

Step 5: Enter DMARC Record Details

Create a new TXT record with the following details:

• Type: TXT
• Host Name: _dmarc
• TTL: Leave it at the default value (usually 3600 seconds or 1 hour).
• Data: Add your DMARC policy. Below is a standard example:
  v=DMARC1; p=quarantine; rua=mailto:[email protected]; ruf=mailto:[email protected]; fo=1;

Replace [email protected] with your actual email address (e.g., [email protected]) to receive aggregate and forensic reports.

Here’s a quick breakdown of the DMARC policy elements:

• p=quarantine: Instructs receiving servers to mark suspicious emails as spam.
• rua: Specifies where to send aggregate reports.
• ruf: Specifies where to send forensic reports.
• fo=1: Requests detailed failure reports.

Step 6: Save the Record

After entering the details, click Save to apply the changes. The new DMARC record will now be active for your domain.

Why is DMARC Important?

• Prevents Spoofing: Protects your domain from being misused for phishing attacks.
• Improves Deliverability: Authenticated emails are less likely to be flagged as spam.
• Provides Visibility: Aggregate reports help you monitor and optimize your email security practices.
