DMARC: Safeguarding Your Email Integrity

This article applies to:

DMARC, or Domain-based Message Authentication, Reporting & Conformance, stands as a robust email security measure, fortifying your domain against cyber threats. Let's unravel the essence of DMARC and its pivotal role in asserting control over email deliverability while safeguarding your brand's integrity.

Understanding DMARC

At its core, DMARC serves as a standard email authentication protocol combating cyberattacks.

DMARC collaborates with established authentication protocols like Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM). Together, they fortify domains against emails impersonating legitimate organizations—a deceitful tactic known as spoofing.

DMARC's Functionality

DMARC empowers email senders to dictate the course for emails authenticated via SPF or DKIM. These instructions can route these emails to the junk folder or entirely block them.

This proactive measure aids Internet Service Providers (ISPs) in effectively identifying spammers and thwarting malicious emails from infiltrating users' inboxes. Moreover, DMARC fosters transparency by offering enhanced authentication reporting, elevating email integrity.

Benefits of Embracing DMARC

Consider these four compelling reasons to adopt and monitor your DMARC record:

  1. Anticipating Industry Shifts: Google and Yahoo mandating DMARC authentication for sending emails to their domains starting Feb 1, 2024, with expectations of other providers following suit.

  2. Safeguarding Sending Reputation: Shield your brand by preventing unauthorized parties from dispatching emails under your domain. In certain cases, merely publishing a DMARC record can enhance your reputation.

  3. Enhanced Email Program Visibility: DMARC reports illuminate your email program, revealing the sources sending emails from your domain.

  4. Ensuring Future Email Deliverability: DMARC instills a consistent policy for handling unauthenticated messages, nurturing a more secure and trustworthy email ecosystem—keeping you off spam lists.

Implementing DMARC in Keap

During the domain authentication process, as you set up your email domain and domain host, you'll encounter a section dedicated to configuring your DMARC record. You will only need to authenticate domains that you intend to send mail from. 

Within this section, you'll be presented with three policies to choose from: None, Quarantine, and Reject. Keap recommends opting for the None policy to align with the forthcoming email requirements enforced by Google and Yahoo starting February 1, 2024.

If you decide to select the Quarantine or Reject policies, it's crucial to comprehend and monitor the DMARC reports and associated services diligently. These reports and monitoring tools help you ensure the accuracy of your email authentication settings, particularly the threshold you set (ranging from 0 to 100%). Incorrectly setting this threshold too high might lead to your emails being diverted to the junk folder or even rejected outright. Understanding these implications is essential before opting for Quarantine or Reject policies. Click here to learn more about DMARC reports.

Understanding DMARC Policy Actions

  • p=none

When the DMARC policy is set to p=none, it implies an observational mode. In this setting, no action is taken against unauthenticated emails that fail SPF or DKIM checks. Instead, the receiver continues to accept all emails, but it generates and sends reports (aggregate and forensic) to the specified email address(es) in the DMARC record. This policy is ideal for monitoring and analyzing the authentication status of your domain's emails without impacting their delivery.

  • p=quarantine

Setting the DMARC policy to p=quarantine instructs the email receiver to handle unauthenticated emails by diverting them to the recipient's spam or junk folder. While not outright rejecting these emails, this policy gives a signal to the receiving server to treat them cautiously, increasing the chances of them being marked as spam. It provides a balance between observation and action, helping protect recipients while still allowing access to messages.

  • p=reject

With the p=reject policy, the email receiver is directed to reject all unauthenticated emails that claim to originate from your domain. This strict setting ensures that only emails that pass SPF and DKIM authentication can reach the recipient's inbox. Any email failing these checks is rejected outright, preventing delivery to the recipient. The p=reject policy offers maximum protection against spoofing and phishing attacks by ensuring stringent email authentication compliance.
