Stop Email Spoofing: How DMARC Protects Your Business

DMARC Protects Your Business spoofing

Have you ever received an email that looked like it came from a trusted company—but it was actually a scam? That’s called email spoofing, and it’s one of the most common ways cybercriminals trick people into giving up sensitive information.

At US Service Center, we specialize in helping organizations secure their email systems and improve deliverability. One of the most powerful tools we use is called DMARC.

🛡️ What Is DMARC?

DMARC stands for Domain-based Message Authentication, Reporting & Conformance. It’s a security protocol that helps protect your organization’s domain from being used in phishing attacks.

DMARC works with two other tools:

  • SPF (Sender Policy Framework) – Verifies that emails are sent from approved servers.
  • DKIM (DomainKeys Identified Mail) – Adds a digital signature to emails to prove they haven’t been tampered with.

Together, these tools help ensure that only legitimate emails are sent from your domain—and that fake ones get stopped.

🔧 DMARC Policy Levels

DMARC gives you three options for how to handle suspicious emails:

1. None (Monitor Only)

  • 📋 This setting doesn’t block any emails.
  • It simply monitors email traffic and sends reports about which messages passed or failed the checks.
  • Best for: Starting out and identifying misconfigurations.

2. Quarantine

  • ⚠️ Emails that fail the checks are flagged as suspicious.
  • They’re usually sent to the spam or junk folder.
  • Best for: Transitioning to stronger protection while still allowing emails through.

3. Reject

  • 🚫 Emails that fail the checks are blocked completely.
  • They’re not delivered at all.
  • Best for: Full protection once your email systems are properly configured.

🧠 Why DMARC Matters

Implementing DMARC helps your organization:

  • Prevent email spoofing and phishing attacks
  • Protect your brand reputation
  • Improve email deliverability and trust
  • Gain visibility into who’s sending emails on your behalf
