Email assessment · methodology v4

Check email infrastructure

The score assesses DNS foundations, email authentication and mail transport only. Websites, HTTP headers, HTML basics and blocklists do not affect email score, rating, coverage or weekly ranking.

Domain

Start check

Enter only the domain, for example example.com — without https://, a path or an email address.

Each domain can be checked at most once every five minutes. Opening this page does not start a check; anonymous SMTP, mailbox and port scans are excluded. Completed public checks may appear temporarily in the weekly overview with the domain, rating and time. Verified owners can withdraw visibility.
