Under reject, messages that fail DMARC are <a href="https://knowledge.workspace.google.com/admin/security/recommended-dmarc-rollout">rejected by receiving servers and never delivered</a>. That includes the invoices from a billing tool nobody set up DKIM for.</p> <p>A staged move from none to quarantine to reject, using the pct= tag and the daily aggregate reports, gets a domain to full enforcement without dropping mail you meant to send.</p>
