Benefits
Good to know about this tool
Finds and breaks down a domain's DMARC record — shows policy, percentage, and reporting addresses.
DMARC builds on SPF and DKIM and defines what happens to email failing both checks — without DMARC, it's up to each receiving server to decide.
- Check whether DMARC was added after setting up SPF/DKIM
- Determine whether a domain only monitors (p=none) or actively protects
- Read reporting addresses for monitoring tools
- Start with p=none and review reports before moving to quarantine/reject
- Ramp pct gradually up to 100
Frequently Asked Questions
What does policy 'none' mean?
Policy 'none' — DMARC only monitors, it doesn't take action on failed checks.
How is this different from SPF/DKIM?
