What is DMARC?
DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that provides a method for domain owners to protect their domain from unauthorized use, known as email spoofing. By implementing DMARC, organizations can help prevent spammers from sending emails on their behalf and improve their overall email security.
Why is DMARC Needed for Google Workspace?

As a popular cloud-based productivity suite, Google Workspace (formerly G Suite) provides businesses of all sizes with email, calendar, and collaboration tools. Due to its large user base, Google Workspace has become a target for cybercriminals who attempt to send phishing emails, which can lead to data breaches and loss of sensitive information. Using DMARC in Google Workspace can help protect your organization by:
- Preventing email spoofing and phishing attacks
- Improving email deliverability
- Increasing domain trustworthiness
- Enhancing brand reputation
- Monitoring email traffic and identifying potential threats
How to Set Up DMARC in Google Workspace
Step 1: Ensure Proper SPF & DKIM Setup
Before implementing DMARC, it's essential to ensure that your organization has properly set up the Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) records. SPF verifies the sender's IP address, while DKIM ensures the email content has not been tampered with during transit.
Step 2: Create a DMARC Record
A DMARC record is created as a TXT record in your domain's DNS settings. It consists of the DMARC version, policy settings, and optional reporting options. A DMARC record should look like this:
_dmarc.example.com. TXT "v=DMARC1; p=none; rua=mailto: [email protected]"
In the example above, "v=DMARC1" indicates the DMARC version and "p=none" is the policy action (allowing emails to continue to be delivered even if they fail DMARC checks). The "rua" tag is for configuring where DMARC reports should be sent.
Step 3: Configure DMARC Record in Google Workspace
Log in to your Google Workspace Admin console, and navigate to the "Domains" section. Click on "Manage Domain" and access the "DNS Settings" for the domain you want to add the DMARC record for. Create a new TXT record with the appropriate DMARC settings, and save your changes.
Step 4: Monitor DMARC Reports
After implementing DMARC, it's important to regularly monitor your reports to identify potential issues or threats. These reports provide valuable insights into your email traffic, such as authentication success rates, sources of unauthenticated emails, and messages that may be malicious or unwanted.
Step 5: Adjust DMARC Policy as Needed
Based on the DMARC reports, you may need to adjust your policy settings to better align with your organization's email security needs. For example, you can change the policy action from "none" to "quarantine" or "reject" to enforce stricter email filtering.
Google Workspace DMARC Example:
Consider an organization named "Acme Corp" that uses Google Workspace for their email communications. Acme Corp has properly set up SPF and DKIM records. They create a DMARC record with the policy action set to "none" initially to monitor their email traffic without impacting deliverability. After analyzing the DMARC reports and identifying potential issues, Acme Corp updates their policy action to "quarantine" to filter out emails that fail DMARC checks. By implementing Google Workspace DMARC, Acme Corp can protect their domain from email spoofing and improve their overall email security.
Implementing Google Workspace DMARC is an essential step in safeguarding your organization's email communications and protecting sensitive data from potential threats. By following the steps outlined in this blog post, you can successfully set up DMARC and enhance your email security.
