How this service works
Mail health report with an A-F grade in one call: MX records present and resolvable, SPF present and syntactically sane (mechanism count, -all/~all), DMARC policy strength, DKIM selector hints (common selectors probed), MTA-STS and TLS-RPT presence, and BIMI. Returns the grade, score and concrete fixes. $0.01 per domain.
Output
Returns a letter grade (A–F), a numeric score, and per-check results covering: MX records (presence and resolvability), SPF record (presence, mechanism count, -all/~all strictness), DMARC (policy strength: none/quarantine/reject), DKIM (hints from probing common selectors), MTA-STS presence, TLS-RPT presence, and BIMI record presence. Also includes concrete, actionable remediation recommendations for each failing or weak area.
Example use cases
Pre-send deliverability audit
“Before we launch our email campaign, can you check the mail health grade for ourbrand.com and tell me if our SPF, DMARC, and DKIM are set up correctly?”
Vendor domain due diligence
“We're about to onboard a supplier who'll be emailing our clients — can you audit vendorsupplier.io's email security grade and flag any weak spots like missing DMARC or SPF issues?”
Internal IT remediation report
“Can you pull the full email health report for ourcompany.net — I need the A-F grade, the score, and a list of concrete fixes I can hand to our IT team?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/monitor/mail-healthWhen to prefer
Choose this endpoint when you need a comprehensive, single-call email security audit covering all major standards (MX, SPF, DMARC, DKIM, MTA-STS, TLS-RPT, BIMI) with an overall grade and actionable fixes, rather than querying individual DNS record types separately. Ideal for pre-send deliverability checks, vendor due diligence, or generating IT remediation reports.
Side effects
- Domain does not exist or is not resolvable — returns an error or empty results
- DNS lookup timeout for one or more record types may result in partial data
- DKIM selector detection is hint-based (common selectors only) and may miss custom selectors
- No input domain provided — API returns a validation error
- Rate limiting or payment failure returns 402 or 429 status
