With Google’s and Yahoo’s New Email Rules: DMARC will be the gold standard wise marketers will embrace:
Since February of this year, significant changes by Google and Yahoo have transformed email marketing, potentially reducing brand email revenue if not appropriately actioned. A stringent spam rate threshold, where a minimal number of emails marked as spam, could classify a sender as a spammer, affecting many brands under current practices, is one of the key concerns. Additionally, a new one-click unsubscribe requirement could lead to a surge in opt-outs, challenging standard operations most brands follow. These changes require us to take a deeper look into current email marketing tactics and place a heightened focus on diversifying retention marketing strategies with an omnichannel approach to include SMS, push notifications, and direct mail.
Amid these imminent changes, savvy marketers must turn their attention to Domain-based Message Authentication, Reporting, and Conformance (DMARC) as a formidable solution. DMARC, often overlooked, has the potential to verify emails, diminish the risk of being labeled as spam, and enhance delivery rates by adhering to stricter email standards. Embracing DMARC empowers marketers with unprecedented control over their email reputation, mitigating the risk of legitimate emails being erroneously marked as spam.
Not familiar with DMARC? Let’s begin:
Domain-based Message Authentication, Reporting, and Conformance (DMARC)
DMARC, short for Domain-based Message Authentication, Reporting, and Conformance, is an advanced email authentication framework. DMARC, introduced in 2012, stands as a robust method designed to thwart malicious email impersonation. Positioned as a standard in email security, DMARC functions as a primary defense mechanism for email programs against harmful emails. To check if you’re already using DMARC, there are available tools for a quick assessment.
Traditionally, email providers relied on filters and feedback to spot spammers, sometimes wrongly blocking genuine emails. DMARC lets senders set rules for real email sources and tells ISPs to reject fake ones. For protecting against email attacks and maintaining your reputation and delivery – it is essential. Furthermore, DMARC compliance is now mandatory for bulk senders, especially for those sending to Gmail and Yahoo, reflecting stricter standards and authentication requirements set by these providers.
Understanding the Mechanics of DMARC
It’s not just a line of code added to your DNS TXT record, but a comprehensive process that includes several key stages for enhancing email security and integrity. Initially, DMARC relies on the foundations of SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail), two existing email authentication methods. SPF allows email senders to specify which IP addresses are authorized to send emails on behalf of their domain, while DKIM provides an email authentication method through a digital signature.
In the DMARC process, the record includes specific tags and values that dictate how recipient servers should handle emails that don’t pass authentication checks. These tags, such as ‘p=reject’ or ‘p=quarantine’, provide instructions on whether to reject, quarantine, or monitor unauthenticated emails. The ‘rua=’ tag says where to send email authentication reports. Which in turn, helps you to understand email traffic and policy improvement.
Post-implementation, DMARC’s effectiveness is measured through detailed reports – which are vital for understanding your email traffic. They help identify the servers sending emails for you, how recipient servers handle them (pass or fail DMARC checks), and show DMARC pass rates. In addition, they show how each receiving mail server handles unauthenticated messages. An optional tag, ‘ruf=’, can be used for receiving detailed forensic reports, offering a deeper insight into individual failed emails, although not all providers support this tag. Regularly checking DMARC reports is important for fine-tuning policies, as it can help solve issues like genuine emails being treated as spam, and helps to prevent phishing and spoofing.

Steps for Setting Up DMARC
1. Prepare Your Domain
Setting up SPF and DKIM for your domain is the initial step. To set up SPF and DKIM, add the SPF DNS TXT record (found in your Email Service Provider settings) and the DKIM record (transferred from your ESP) to the TXT DNS file within your DNS provider’s settings. This step is crucial for authenticating your emails.
2. Set Up a Group or Mailbox for Reports
Create a dedicated mailbox or group for receiving DMARC reports, as these XML reports tracking email activity can accumulate rapidly. It’s advisable to consider a third-party service for efficiently managing and interpreting these reports, especially for larger organizations receiving numerous reports.
3. Audit Your Sending Domains
Conduct an audit of your email-sending domains to distinguish legitimate domains from potentially fraudulent ones. This proactive action is vital for managing domains, particularly in larger organizations with multiple teams, saving time and preventing future complications.
4. Choose a Policy
DMARC empowers email senders to actively shape their authentication policies. This shift allows senders to transition their policy from a permissive state (‘none’) to a more restrictive one (‘quarantine’), and ultimately to the strictest level (‘reject’). This progression is analogous to moving through a traffic light system.
None: Using the ‘p=none’ tag maintains the status quo, delivering messages normally. This setting is beneficial for observing DMARC reports without impacting email delivery, but note that BIMI doesn’t work with DMARC settings where ‘p=none’ is chosen.
Quarantine: Direct unauthenticated emails to the spam folder until their origin is fully verified.
5. Publish Your TXT Record
Navigate to your domain host’s DNS settings in the management console. Under the DNS hostname, enter the record name: ‘_dmarc.yourdomain.com’. Under the DNS record value, enter your DMARC record. Save the changes.
6. Analyze Your Reports
With your DMARC record in place, reports start landing in your mailbox. These reports provide data on messages passing or failing SPF and DKIM authentication.
7. DMARC XML Files
Extensible Markup Language (XML) files, designed for machine reading, can be challenging for humans to interpret. Convert the records to tabular format using a relational database, convert XML to HTML with an XSL style sheet, or use a third-party SaaS provider for receiving, storing, and analyzing reports.
8. Deal with Third-Party Apps
Given the unlikelihood of remembering all IPs from third-party apps, follow a three-step process:
- Assess: Audit your sender IPs and cross-match with the IPs on your reports.
- Remediate: Add DMARC records to all verified sending sources.
- Maintain: Ensure
Congratulations, you have safely and successfully implemented DMARC!
The Bottom-Line
These adjustments may present some initial hurdles in the grand scheme of things, but they are a resounding leap in the right direction. They champion enhanced email practices, protect your sender reputation, and guarantee that your emails find their way to precisely the right audience. So, while it may appear daunting at first, these changes hold the promise of skyrocketing your success as an email marketer. Embrace them with enthusiasm and seize the opportunity to elevate your email marketing game!
