What a healthy email domain needs
MX records tell other systems where to deliver mail. SPF identifies permitted sending infrastructure. DMARC publishes alignment and enforcement policy. These records solve different problems, so this report keeps them separate instead of collapsing them into a vague score.
What is not included
DKIM records require a selector, so use the DKIM record checker when you know the selector from your mail provider or an email's DKIM-Signature header.
