Why Fixing One Record Isn't Enough

SPF

Lists authorized sending servers. Prevents spoofing from unauthorized IPs.

DKIM

Adds a cryptographic signature to outgoing emails, proving they haven't been tampered with in transit.

DMARC

Tells receiving servers what to do with emails that fail SPF/DKIM. Enables reporting and enforcement.

BIMI

Displays your brand logo next to emails in supported inboxes. Requires a valid DMARC policy.

MTA-STS

Enforces TLS encryption for incoming mail, preventing downgrade attacks and eavesdropping.

TLS-RPT

Provides reporting on TLS connection failures, helping you identify encryption issues.

MX Records

Specifies which mail servers handle incoming email for your domain.

A Records

Maps your domain to an IP address. Essential for web and mail server resolution.

NS Records

Identifies your authoritative name servers, the foundation of your DNS infrastructure.
