What it checks
MX provider clues, SPF presence, duplicate SPF records, weak SPF endings, DMARC policy, aggregate reporting, and common DKIM selector hints.
Email DNS Fix Pack
Check SPF, DKIM, and DMARC before email trust becomes expensive.
Enter a domain and generate a plain-English risk report from public DNS records. No mailbox login, no DNS account access, no customer list upload.
What it does not claim
It does not guarantee inbox placement, edit DNS, inspect private mailboxes, or certify compliance. It is a preflight report for the domain owner or mail provider.
Paid test offer
Start with a $29 one-page report or $79 fix pack. For agencies, test a $199 batch report for 10 domains after at least one interested reply.
Public DNS checker
Generate an email DNS risk report.
Use a public business domain. The browser queries public DNS records through Cloudflare DNS-over-HTTPS and keeps the report in this page.
Do not enter private mailbox credentials or customer lists. A domain name is enough.

Validation rule
Only sell the report if the risk is specific.
Do not send generic cold email. The first message must mention one concrete public DNS finding. One target gets one first message. No follow-up unless they reply.
