Questions
What do you check?
Six public DNS records: MX (where mail goes), SPF, DKIM, DMARC, MTA-STS and BIMI. MX and SPF are the basics. DKIM and DMARC are optional and help mail get delivered. MTA-STS and BIMI are optional too.
Why is my domain listed?
Your domain is among the popular public domains in the public Tranco ranking. We list it because its DNS records are public. Being listed says nothing about you or your company.
How often are the pages updated?
Once a week. Each page shows the date of the last check. For an up-to-date result, run a live check.
How do I remove my domain's page?
Use the removal form and enter only the domain name. Our team reviews every request within 7 days, and approved pages are removed. Ask to remove a page
These results are a snapshot of public DNS on the date shown. They are not a security rating, and records may have changed since then.
How we check
We read public DNS records only: the same records any mail server reads before it delivers a message.
We check each listed domain once a week. We never connect to the domain's mail servers and never send it any email.
The list covers popular public domains from the public Tranco ranking.
