What is DMARC and how can it help you?

[samiaseo222]

Technical setup is a crucial but somewhat confusing step when you're setting up the perfect domain.


We'll look at what DMARC is, how to set it up, and why it's so important.

What is DMARC
DMARC stands for “Domain-based Message Authentication, Reporting, and Conformance.”

It is an email authentication and security communication directors email lists protocol designed to help organizations protect their email domains against phishing, spoofing, and other email-based attacks.

DMARC builds on two other email authentication protocols, Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM), to provide a comprehensive approach to email authentication and validation.

DMARC is a technical specification used in email authentication.

Its purpose is to protect sending domains from unauthorized use. By this we specifically mean that it helps prevent phishing, business email compromises (BECs) , and other email scams.

Why is DMARC important?
Not all of us use email for the same purposes.

We've grouped email users into three different categories so that you can understand the usefulness of DMARC regardless of what your primary job is.

Sometimes messages fail during the authentication process.

The DMARC policy provides all the information you need on how to filter these messages.

When in doubt, mailbox providers will often send an unauthenticated message, as a customer is more likely to delete spam than miss a real email that could have been useful and meaningful.

That's why spam sometimes ends up in your inbox.

All major mailbox providers support DMARC. In fact, implementing DMARC is a signal to these providers that you are a responsible and reliable sender that they can trust.
