What is DMARC?
DMARC is an email authentication protocol designed to protect your domain from unauthorised use, such as phishing and email spoofing. It builds on two existing mechanisms, SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail), to ensure that incoming emails are genuinely from the domain they claim to be from.
By implementing DMARC, businesses can significantly reduce the risk of email-based attacks and enhance their email security posture.
How Does DMARC Work?
It works by aligning the “From” header in an email with the SPF and DKIM authentication results. When an email is received, the recipient’s mail server checks the DMARC policy published in the sender’s DNS records. Based on the policy, the server decides whether to accept, quarantine, or reject the email.
This process helps prevent malicious emails from reaching the inbox and provides valuable feedback to the domain owner through reports.

Benefits of DMARC for Businesses
In today’s digital age, email remains a primary communication channel for businesses. However, it’s also a favourite target for cybercriminals. Here’s why implementing DMARC is crucial for your organisation:
1. Enhanced Email Security
It significantly reduces the risk of phishing attacks, business email compromise (BEC), and other email-based threats. By verifying the authenticity of incoming emails, it helps protect your employees, clients, and partners from falling victim to sophisticated email scams.
2. Brand Protection
Your domain is an essential part of your brand identity. DMARC prevents unauthorised use of your domain, safeguarding your reputation and maintaining trust with your stakeholders. This protection is invaluable in an era where a single security breach can cause lasting damage to a company’s image.
3. Improved Email Deliverability
By implementing it, you’re signalling to email providers that you take security seriously. This can lead to improved email deliverability rates, ensuring that your legitimate emails reach their intended recipients.
4. Comprehensive Visibility
It provides detailed reports on email authentication results, giving you unprecedented visibility into your email ecosystem. This information can be invaluable for identifying potential security threats and fine-tuning your email infrastructure.
5. Compliance and Risk Management
Many industries have strict regulations regarding data protection and cybersecurity. Implementing DMARC can help your organisation meet these compliance requirements and demonstrate a proactive approach to risk management.
Implemention: Best Practices
Now that we understand what DMARC is and why it’s essential, let’s explore how to implement it effectively:
1. Start with SPF and DKIM
Before implementing DMARC, ensure that you have properly configured SPF and DKIM for your domain. These protocols form the foundation of authentication.
2. Begin with a Monitoring Policy
When you first implement, start with a “p=none” policy. This allows you to monitor email traffic and authentication results without affecting email delivery.
3. Analyse Reports
Regularly review the reports generated by DMARC. These reports provide valuable insights into your email ecosystem and can help you identify potential security issues.
4. Gradually Tighten Your Policy
As you gain confidence in your implementation, gradually tighten your policy from “p=none” to “p=quarantine” and finally to “p=reject” for maximum security.
5. Keep Your Record Updated
Regularly review and update your DMARC record to ensure it reflects your current email infrastructure and security needs.
The Impact on Your Business
Implementing DMARC can have a significant positive impact on your organisation.
1. Reduced Phishing Attacks
It effectively blocks phishing attempts that use your exact domain, significantly enhancing your email security.
2. Increased Trust
By protecting your domain from unauthorised use, it helps maintain trust with your customers, partners, and employees.
3. Cost Savings
By preventing email-based attacks, it can save your organisation from potential financial losses associated with cybercrime.
4. Improved Brand Reputation
Its implementation demonstrates your commitment to cybersecurity, enhancing your brand’s reputation in the digital space.
5. Better Email Insights
The reporting feature provides valuable data that can help you optimise your email marketing efforts and overall email infrastructure.
