Email communication is an integral part of business operations and customer experience. That’s why protecting your domain name and brand reputation is of utmost importance.

Cybercriminals are constantly developing advanced techniques such as phishing and email spoofing to take advantage of vulnerabilities in email systems, placing brands at risk of a harmful breach. That’s where Domain-based Message Authentication, Reporting, and Conformance (DMARC) comes into play.

Let’s discuss DMARC, its benefits, and how it can help protect your domain name and brand reputation.

Benefits of Using DMARC

Protects Brand Reputation

Phishing can not only damage your brand reputation but also lead to a significant loss of customer trust.

DMARC helps protect your brand reputation by verifying that emails are genuine. Brands can establish policies on how emails should be authenticated and communicated, and DMARC checks that these policies are being followed.

Defends Against Phishing Attacks

Phishing attacks are meant to steal sensitive information through an email that appears to be from a legitimate source. These attacks can result in significant reputation harm, especially to companies that suffer data breaches.

Provides Authentication Reporting

To ensure complete domain protection, getting visibility on who is attempting to send unauthorized emails is a crucial aspect. DMARC provides visibility into all inbound email traffic and generates detailed reports on both legitimate and fraudulent emails.

These reports answer important questions during investigations into cyberattacks and enable companies to take appropriate actions to prevent breaches.

Enforces Sender Policies

DMARC provides a way to enforce email policies by requiring that all emails pass authentication checks before being delivered to the recipients. It provides several policy options, including quarantine and rejection, allowing the company to decide how to deal with any unauthorized emails.

Improves Email Deliverability

One of the major advantages of implementing DMARC is that it enhances email deliverability. Email service providers use DMARC to verify that emails are coming from your domain and that your domain is not being used in potential phishing or spoofing attacks.

How DMARC Works

When an email is sent from one domain and arrives at the recipient domain, SPF and DKIM authenticators check the email.

DMARC, Sender Policy Framework (SPF), and Domain Keys Identified Mail (DKIM) are all email authentication protocols used to improve email security.

SPF is an email authentication program that prevents email spoofing by checking the sender’s IP address against a list of authorized IP addresses. DKIM verifies the authenticity of the emails’ content by adding a digital signature to the message header. DMARC uses both SPF and DKIM to authenticate emails.

Attacks DMARC Protects Against


Phishing attacks are the most common type of email attack and can be detrimental to an organization as scammers can use the information for fraudulent activity.

Email Spoofing

Email spoofing is a technique used by attackers to change the email’s header so that it appears from a legitimate source, tricking users into clicking a link designed to steal information.

Domain Name Abuse

Attackers often use domain names that appear to be legitimate to launch an attack.

DMARC checks the source of the email to ensure that it’s legitimate before it’s delivered and blocks it if it fails the check.

Bottom Line

DMARC is an essential tool for protecting your domain name, brand reputation, and customer trust. By verifying email sources, checking authenticity, and providing policy enforcement, DMARC can prevent phishing attacks and email spoofing.

DMARC is a must-have defense measure worth considering for all organizations that rely on email communication. It ensures that your email communication remains secure, improves email deliverability, and helps you maintain your brand reputation.
