Enter the root domain you want to protect with DMARC.

Optional policy specifically for subdomains.

IMPORTANT
DMARC is an enforcement and reporting layer
DMARC does not replace SPF or DKIM. It evaluates whether authenticated domains align with the domain visible to the recipient and lets domain owners publish handling and reporting preferences.
