Why Ready DNS exists

Ready DNS exists to turn public MX, SPF and DMARC records into a readable first-pass report for domain owners and small teams.

How it works

The checker queries public DNS through a resolver service, then applies documented diagnostic rules. It cannot inspect private accounts, individual messages or every sender.

Editorial standard

Every page should answer a real question within this tool’s narrow subject. We explain assumptions, include worked examples where useful, state important limitations and avoid publishing unrelated pages merely to capture searches.

Review and corrections

Product behavior is checked against the examples on this site. Editorial pages are reviewed when lookup behavior or email-authentication guidance changes. Significant corrections should update both the guidance and its visible review date.
