Help - Articles/Guides with advanced analysis


Does anyone have any good reads - articles or guides on how to do advanced analysis of DMARC reports?

After getting my company in line with all sending domains and services, having policy=none for weeks showed me 100% compliance for SPF, DKIM and DMARC.
After leaving it like that for a few weeks I’ve started implementing policy=quarantine at 5% steps as recommended, but am now seeing SPF and DKIM plummet to as low as 80% in some instances, with no changes made here to our domains or services.

I’ve tried the videos and guides here, but there’s no real detail.
Has anyone written a guide to properly understanding Detail Viewer for example?

Thanks in advance.


Please see this link.

However, each situations are unique, and changing the policy alone would not cause a drop in compliance. Causes of compliance drop can vary widely, from new accounts being onboarded, shadow IT and more. Don’t hesitate to reach out to with your questions, we can endeavor to provide you more context and guidance after getting to know a bit more about you and your organization.

I hope this helps.


Thanks for the response and the link.
I’ve worked out most of what was in the article myself already, so will reach out to support as suggested.

Thanks once again.
