Frequently asked questions
What does the email DNS health score measure?
It combines the four DNS records that determine whether your mail authenticates and reaches the inbox (SPF, DKIM, DMARC and MX) into a single 0-100 score.
What is a good score?
Higher is better. A strong domain publishes a valid SPF record within the lookup limit, DKIM keys, an enforcing DMARC policy and working MX records, which pushes the score toward 100.
How often is the score updated?
We check live DNS on every run and cache the result, refreshing it daily so the page stays current as you fix records.
