Best of the inbox: rolling out DMARC without breaking mail
The enforcement deadlines spooked everyone. This is the calm, staged path the good guides agree on.

🚀 Stage 1
— Publish p=none + rua reporting — collect 2-4 weeks of aggregate reports before changing anything. You're observing, not enforcing.
— Map every sender — ESP, CRM, invoicing, support tool. Each needs its own SPF include and DKIM key or it fails alignment.

🔧 Stage 2
— Fix alignment, not just pass — a source can pass SPF yet fail DMARC if the From domain doesn't align. Check the report XML for this exact gap.
— Move to p=quarantine pct=10 — ramp the percentage, watch reports, then climb.

🛡 Stage 3
— p=reject only when reports are clean — and add BIMI once you're there for the logo payoff.

Why these picks: staged percentages and a sender inventory are what separate a smooth rollout from a Monday outage.
