Frequently Asked Questions
What does the DMARC Checker look at?
It fetches your DMARC record from DNS and validates the syntax, policy strength, alignment settings, and reporting addresses. You get a clear picture of whether your domain is actually protected or merely monitored.
My record says p=none. Is that a problem?
It means you are collecting reports but not blocking anything, so spoofed mail sent as your domain still lands. It is the right starting point, but by 2026 mailbox providers expect senders to move toward quarantine or reject.
Is the DMARC Checker free?
Yes. Create a free Brainito account and run checks as often as you like. It is worth re-checking after any DNS change and before ramping up email volume, since DMARC issues are cheap to fix and costly to ignore.
