A one-time check tells you what's published today.
It can't tell you who's actually sending as your domain, or what changes tomorrow. That's where monitoring comes in.
Who's sending as you
DMARC aggregate reports name every IP that tries to send as your domain — legitimate, shadow IT, and impersonators. A check can't see them.
When things break silently
A DNS edit, a new SaaS tool, an expired key — any of these can quietly break alignment. Monitoring catches it; the next quarterly check finds out the hard way.
When you're ready to enforce
Moving from p=none to quarantine or reject without data is how legitimate mail gets blocked. Monitoring gives you the data and the green light.
