What is DMARC?


DMARC stands for Domain-based Message Authentication, Reporting & Conformance.


It is a state-of-the-art email authentication protocol that has been developed to offer businesses, institutions and individuals (email domain owners) the ability to protect their dedicated domain from unauthorized access and usage.


This email protocol makes use of Sender Policy Framework (SPF) and Domain Keys Identified Mail (DKIM) to authenticate email messages.


DMARC is designed to seamlessly blend with your organization’s present inbound email authentication process.


In simple words the system works by helping email receivers validate the purported message from the senders based on the information that receivers have about the sender from DMARC record checker.

How Does DMARC Work?

DMARC relies on the established SPF and DKIM standards for email authentication. It also piggybacks on the well-established Domain Name System (DNS).


DMARC uses established SPF and DKIM protocols for email authentication and validation. It also makes use of the Domain Name System (DNS) to ensure every email sent from a particular domain is authenticated against a DMARC record checker. We deploy DMARC for your emails in five easy steps –

  1. We start by deploying DKIM and SPF. This is the first and most important step on the process
  2. We define appropriate identifiers to make sure your mailers aligning align to them
  3. Publish your unique DMARC record with “p=none” flag set for your email policies, with additional request for data reports
  4. Monitor the data constantly and modify your mail streams whenever required.
  5. Modify your DMARC policy flags from “p=none” to “p=quarantine” to “p=reject” when needed

At SNPL we help you in defining your DMARC protocol that defines how DMARC Record Checkers need to handle unauthorized use of your email domains. We help you in instituting custom policy in your DMARC record that is hard to breach for the hackers and preserves the integrity of your official email accounts and prevents damage to your brand reputation. We are a team of experienced Internet architects that stays abreast with the latest developments in Internet Security and implement the latest best practices in every project that we undertake.

Benefits of DMARC

Domain Visibility


It boosts your domain’s visibility by offering you real-time feedback on the use of your domain across cyberspace. With DMARC reporting tool you will have complete access to data on all email messages sent from your domain. You get insights on –

  • Who is sending emails from your domains and to who?
  • Is there any unusual volumes of emails from particular account?
  • How many emails have been sent by the users?
  • What percentage of the emails were validated as legal sources?
  • Which sources are misusing your domain for phishing purpose?
  • Info on the authentication method that is broken and needs to be fixed.


Command over Domain


With DMARC your business gets complete command over the domain. You will be able to track down any abuse or misuse of the domain and pinpoint to the email message, sender, receiver, time etc. in the DMARC report. This also helps you put curb on unauthenticated emails by legit users of your domain.


Improved Security


Organizations can easily fall prey to phishing attacks without DMARC. Damage done by phishing and abuse of email messages are severe. With DMARC you will add a security layer to all emails being sent to your customers, vendors and other recipients and prevent impersonation, spoofed messages and spam oriented emails.


Brand Recognition


As much as you care about your brand reputation in the physical world you should do so in the digital space as well. With DMARC your organization’s email would be able to access BIMI (Brand Indicators for Message Identification). This advanced email standard allows your organization to display its Logo in the receiver’s Inbox. Your email instantly grabs attention and also separates itself from spam messages. BIMI can be deployed when you have defined the email authentication standards in DMARC such as “p=quarantine” or “p=reject”

Its time you take complete control and command over your email system and prevent your business from falling prey to phishing attacks and internal abuse of your email platform.
