How to Implement DMARC
DMARC is more than a DNS record — it is a process of taking control of an organization's email infrastructure.
Check the Domain
Run a free DMARC check to see the current authentication status and identify weak spots in the email setup.
Start Collecting Reports
Publish a DMARC record with a monitoring policy to begin receiving reports about who sends email on the domain's behalf.
Fix Email Sources
Use the DMARC Dashboard to identify misconfigured email sources and align SPF and DKIM across all senders.
Enforce a Strict Policy
Move to quarantine to divert suspicious messages to spam, then to reject to block them outright and protect the brand from impersonation.
About Percentage Changes
All percentage changes shown on this page represent percentage points (pp), not relative percentage changes. For example, an increase from 10% to 15% is reported as +5%, meaning a 5 percentage point increase.
