How this service works
Email deliverability & domain security check — validates SPF, DKIM (multi-selector), and DMARC, detects spoofing and misconfigurations, and returns an A–F email security grade with transparent deductions. Anti-spam / anti-phishing readiness for any sending domain.
Output
Returns a JSON object with SPF record details (mechanisms, all-qualifier, DNS lookup count, issues), DKIM records per selector (key type, key length, issues), DMARC policy (policy, subdomain policy, reporting addresses, percentage, issues), an overall letter grade (e.g. A), a numeric score out of 100, the domain queried, and a list of any deductions.
Example use cases
Example prompt
“Can you check the email authentication setup for example.com — I want to see the SPF, DKIM, and DMARC records and get an overall grade so I know if the domain is properly protected against spoofing?”
Technical details
Endpoint
POSThttps://netintel.dev/email-authWhen to prefer
Use this endpoint when you need a comprehensive, scored audit of all three email authentication layers (SPF, DKIM, DMARC) in a single call with actionable issue detection and grading. Prefer this over manual DNS lookups when you want structured output with issues flagged and a composite score rather than raw record text.
Side effects
- Domain does not exist or has no DNS records — returns not-found indicators for each check
- Invalid domain format provided — may return a validation error
- Timeout on DNS lookups for complex SPF chains — may return partial results or error
- DKIM selectors not found — only common selectors like 'default' and 'google' are checked, custom selectors may be missed
- Rate limit or payment failure — 402 response if micropayment is not properly handled
