How to Check if Your SPF and DMARC Are Correct

SPF and DMARC help receiving mail servers decide whether messages from your domain are legitimate. This guide explains how to run a DNS check, read the SPF and DMARC statuses and decide what needs manual review.

FAQ

Does this tool change my DNS records?

No. It only reads public DNS TXT records and reports what it finds.

What if SPF or DMARC is missing?

That usually means your domain needs DNS changes. Review the report and update records carefully with your domain or email provider.
