Frequently Asked Questions
Common questions about DMARC policy simulation
What is a DMARC policy impact simulator?
A tool that shows how changing your DMARC policy affects email delivery. Upload aggregate reports, select a policy, and see which emails would be quarantined or rejected. Prevents blocking legitimate email.
Should I use p=quarantine or p=reject?
Start with p=none (monitor). After 2-4 weeks, move to p=quarantine (spam). Once all legitimate sources pass, use p=reject (block) for maximum protection. Simulate impact before changing.
How long should I monitor before changing policy?
Monitor at p=none for 2-4 weeks minimum to capture all sending patterns. Ensure all legitimate senders pass SPF/DKIM. Monitor p=quarantine for another 2-4 weeks before p=reject.
