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.
