What it does
This is the tag that makes DMARC useful. Aggregate reports tell you every IP sending as your domain and whether each one passed SPF and DKIM — which is the only practical way to find forgotten senders before you move to p=reject. Without rua you are flying blind. To receive reports at a different domain, that domain must publish an authorisation record.
Example
v=DMARC1; p=none; rua=mailto:dmarc@example.com
