About this tool
DMARC is the final step in email authentication, working alongside SPF and DKIM to tell inbox providers what to do with unauthenticated messages. Start with a monitoring policy ("none") and gradually move to "reject" as your senders align. To ensure your records are set correctly, use our DNS propagation checker to verify global visibility. For deep debugging, the email header analyzer will show exactly how your policy evaluated each message.
