DMARC, What it is and Why it Matters...

Simple, easy and effective way of protecting your organisation.

DMARC is the simple, trusted solution that brings together email authentication protocols, and adds reporting and compliance. In just a few easy steps, you can set up DMARC today to protect your organization from email fraud.

What is DMARC?

DMARC stands for Domain-based Message Authentication, Reporting and Conformance. It’s like an identity check for your organization’s domain name. A DMARC policy allows a sender to indicate that their messages are protected, and tells a receiver what to do if one of the authentication methods passes or fails – either send the message or reject the message to junk. Further, DMARC helps prevent the creation of fraudulent email accounts on your organization’s website domain. Best of all, it’s free to use.


DMARC was first created in 2010. It became an initiative in 2015 under the Trusted Domain Project. Currently, DMARC is supported by 85% of consumer US Inboxes. Approximately 70% consumer Inboxes worldwide are protected by DMARC – that’s more than 2.5 billion mailboxes worldwide.

However, the adoption rate of DMARC by businesses and other organizations has been slow. Many organizations are still not aware of DMARC and its benefits.

Many of those who have implemented it, have done so incorrectly, without realizing the full extent of its impact. The DMARC Setup Guide is designed to help organizations through the implementation process, so it is done correctly and can realize its full protection potential.

Detect Fraud, Prevent Threats

DMARC provides a way for participating senders and receivers to streamline the analysis process by coordinating their verification efforts. This prevents spammers and phishers from using valid organization names to conduct cyber attacks, and provides insight into any attempts to spam, phish, or spearphish using your organization’s brand or name. Using DMARC, businesses are able to reduce the likelihood that their domain will be used in an attack, and they’ll be protected against incoming threats from other compromised domains. As a result this can increase customer confidence and build trust in your brand.
