Order your review
Enter a domain you own or are authorized to assess. Your details pre-fill the secure checkout and are saved so your order can be followed through.
Clear limits
A DNS snapshot cannot prove inbox placement, lost sales, compromise or regulatory compliance. The review covers publicly observable SPF, DMARC and MX records; DKIM selectors require separate identification. No DNS changes or remediation are included.
