DMARC Update 1st February 2024

Email Blocked DMARC Update

The Gmail and Microsoft DMARC Policy UPDATE that you may not be aware of is something you need to take note and check ASAP.

In October 2023, Google and Yahoo collaboratively introduced fresh sender criteria for incoming emails to their domains, which was scheduled to be implemented in early 2024. These criteria primarily target bulk senders at the moment.

For an extended period, gmail.com has maintained a DMARC policy record with a “p=none” statement, indicating that the domain owner does not want DMARC validation results to affect the message’s disposition. Consequently, messages impersonating Gmail’s “From” headers have consistently failed DMARC, but the impact has been minimal due to the “p=none” policy.

Effective February 1, 2024, Google is altering this policy statement to “p=quarantine,” signaling a shift in preference. This change means that messages using gmail.com in the “From” domain, which fail DMARC, will be directed to recipients’ spam folders rather than their inboxes. As a result, emails attempting to impersonate Gmail “From” headers are more likely to be classified as spam.

What’s changing with DMARC in 2024

The primary DMARC requirement in 2024, notably imposed by both Google and Yahoo, affects organizations sending over 5,000 emails daily. To ensure the proper delivery of emails and prevent them from being marked as spam, organizations must adhere to the following guidelines:

Authenticate their domain: This involves implementing a DMARC record with a minimum policy of p=none, along with SPF and DKIM records. Additionally, organizations should ensure SPF or DKIM alignment and maintain Forward-Confirmed Reverse DNS (FCrDNS).

Facilitate easy unsubscription: Organizations with a current unsubscribe link in commercial emails must incorporate a one-click unsubscribe feature by June 1, 2024.

Maintain low spam rates: To comply with the requirement, organizations must ensure that spam rates reported in Postmaster Tools remain below 0.3%. Keeping these rates low is crucial for effective email delivery and sender reputation.

Am I Affected By This?

You can easily check your domain name using https://mxtoolbox.com/dmarc.aspx and then search the data for your domain name.

To update or change a DMARC (Domain-based Message Authentication, Reporting, and Conformance) value, you’ll typically need to make modifications to the DNS (Domain Name System) records for your domain. Here are the general steps:

Access your DNS Management Interface:

Log in to the account where your domain is registered or where you manage your DNS settings. This is often with your domain registrar or hosting provider.
Locate the DMARC Record:

Look for the existing DMARC record in your DNS settings. It is a TXT (text) record associated with your domain.

Modify the DMARC Record:

Edit the DMARC record to change the desired values. The DMARC record typically includes parameters like the policy (p), the percentage of messages subjected to filtering (pct), and the destination for aggregate and failure reports (rua and ruf).

Example of a DMARC record:

v=DMARC1; p=none; rua=mailto:your@domain.co.uk; ruf=mailto:your@domain.co.uk; pct=100;

In this example, you could change p=none to p=quarantine or p=reject, depending on your desired policy.

Verify Syntax and Save Changes:

Ensure that the syntax of your DMARC record is correct. Incorrect syntax can lead to misconfigurations. Save the changes after modifying the record.
Propagation Time:

Keep in mind that DNS changes may take some time to propagate across the internet. The duration can vary, but it’s typically a matter of hours to a day.


After the DNS changes have propagated, it’s advisable to test your DMARC configuration using tools like DMARC analyzers or checkers. This helps ensure that your updated DMARC policy is correctly implemented and doesn’t unintentionally impact your email delivery.

Remember that the specific steps may vary slightly depending on your domain registrar or DNS hosting provider. If you’re unsure about the process, it’s recommended to consult the support documentation provided by your domain registrar or seek assistance from your IT department or technical support team. Additionally, changes to DMARC policies should be approached cautiously to avoid unintended consequences on email deliverability.
