DMARC Checker FAQ
How does the tool check DKIM?+
It retrieves the public key from the domain’s DNS and verifies the signature in the email headers.
What if SPF passes but the From address is spoofed?+
DMARC ensures alignment; if SPF passes but the From domain doesn’t match, DMARC will fail.
Is my email address stored or shared?+
Your address is used only to send the report and is not shared with third parties.
Do I need to create any DNS records?+
No, the tool only reads existing DNS records for DMARC, DKIM, and SPF.
How long does it take to get the report?+
You receive one email with a brief overview immediately and a link to the full report shortly after.
