What is DMARC? In 90 seconds

What is Email Authentication?

SPF

Sender Policy Framework — lists the servers allowed to send for your domain. On its own, it does not stop someone from putting your name in the From line.

DKIM

DomainKeys Identified Mail — adds a digital signature to verify your emails haven't been tampered with.

DMARC

Domain-based Message Authentication — checks that the From line people see matches what SPF or DKIM verified, and tells receivers to refuse the fakes. This is the part that stops spoofing.

How We Help

1

Check

We analyze your domain's DNS records to identify misconfigurations, missing DMARC policies, and vulnerabilities.

2

Fix

Our experts implement the correct SPF, DKIM, and DMARC configurations for all your email platforms.

3

Monitor

Continuous automated monitoring with specialist review ensures your compliance is maintained over time.

Why Does This Matter?

Without proper email authentication, your domain is an open door for attackers.

Domain Spoofing

Without DMARC, hackers can send emails pretending to be you — phishing your clients, partners, and employees.

Email Deliverability

Gmail, Microsoft, and Yahoo now require proper authentication. Without it, your emails land in spam or get rejected.

Industry Compliance

Google and Yahoo enforce strict DMARC requirements since 2024. Microsoft joined in 2025. Non-compliance means rejected emails.

Brand Protection

A single spoofing incident can damage years of brand trust. DMARC prevents unauthorized use of your domain name.
