In today’s digital age, phishing and spoofing attacks are lurking dangers in our inboxes. That’s where DMARC (Domain-based Message Authentication, Reporting & Conformance) steps in! 
But how exactly does DMARC work? Let’s break it down.
1. DMARC: What Is It?
DMARC is like a security checkpoint for your emails. It helps domain owners prevent attackers from sending emails that pretend to be from them. It works alongside SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail).
2. Core Mechanisms: SPF & DKIM
SPF verifies that emails come from an authorized server.
DKIM attaches a unique signature to emails, proving they’re genuine.
DMARC combines these to enforce rules and align the email’s “From” domain with SPF & DKIM.
3. How DMARC Works
Here’s a quick rundown:
Email Alignment Check: Confirms if the email’s sender domain matches the authenticated domains from SPF & DKIM.
Policy Definition: Domain owners set a policy (none, quarantine, or reject).
Reporting: Provides reports to help domain owners understand and control their email flow.
Why Should You Care?
Implementing DMARC not only secures your email domain but also boosts your brand’s reputation by preventing email spoofing. 
Spoofing Prevention Better Visibility Enhanced Deliverability
How to Get Started
Start with a “None” Policy.
Analyze DMARC Reports.
Move to “Quarantine” or “Reject” gradually.
Regularly review your policy based on reports.
