Recommended rollout

Start with p=none and a report address for a few weeks, fix any legitimate senders that fail, then move to quarantine, and finally reject. DMARC only passes when SPF or DKIM passes and matches your From domain, so set up both first.

Multiple report addresses can be separated with commas. Confirm the record after publishing with the DMARC Record Checker.
