Why It Matters

Email spoofing is the #1 initial attack vector.

DMARC

Without DMARC enforcement (p=reject), anyone can send email that appears to come from your domain. Your brand, your customers, your partners — all exposed.

SPF

SPF records specify which mail servers are authorized to send on your behalf. Misconfigured or missing SPF lets attackers send from your domain without restriction.

DKIM

DKIM cryptographically signs your outbound email. Without it, messages can be tampered with in transit and inbox providers treat your email as lower-trust.
