Use the email health check to inspect a domain’s public mail and authentication records. It reports an overall score, the results of nine check groups, and dataCompleteness so you can see when a check was missing. The score is a configuration review, not an inbox-placement test.
Enter a domain or full email address at spotzee.com/tools/email-health-check. The service extracts the domain from an email address.

​
Check a domain

1

Submit a domain

Enter a domain or email address. The API also accepts dkim_test_type: quick or full.
2

Check data completeness

Read dataCompleteness.percentage, missingChecks, and failureReason before interpreting the score. A technical failure can leave some groups unmeasured.
3

Inspect each result group

Read the MX, SPF, DMARC, DKIM, BIMI, MTA-STS, TLS-RPT, CAA, and domain results. Each group reports its own score and details where available.
4

Verify a finding before changing DNS

Confirm the relevant record and your provider’s configuration. The result cannot confirm that a real message passed authentication or reached an inbox.

​
How scoring works

The service adds group scores and divides by a fixed 280-point maximum. The configured maxima are MX 30, SPF 60, DMARC 60, DKIM 60, BIMI 0, MTA-STS 10, TLS-RPT 5, CAA 5, and domain 50. dataCompleteness is separate from the score: missing groups contribute zero rather than reducing the maximum.
DKIM results have two known limits. Although the API accepts full, the check uses the same selector set as quick. When that set finds no DKIM selector, the current scoring logic awards full DKIM points. Do not treat a high DKIM or overall score as proof that signing is configured. Check the selector from an actual sent message and verify its DNS record separately.
The check reads public records and domain signals. It does not send a probe message, measure open rates, or establish delivery. For a focused SPF record read, see SPF lookup; for a focused DMARC record read, see DMARC lookup. The same check is available through the Spotzee Extended API at POST /generic/email/email-health-check. API calls use your credit balance; see pricing for the current rate.
