How this service works
Checks whether a domain appears technically configured for email delivery, from direct public DNS records only: MX presence, SPF presence, DMARC presence and policy, and an optional DKIM selector check. Queries DNS over HTTPS against a public resolver -- no test emails sent, no mailbox existence verification, no personal data, no leaked-email databases, no proprietary deliverability dataset.
Output
Returns a structured result indicating whether the queried domain has MX records present, SPF record present, DMARC record present and its policy level (e.g. none/quarantine/reject), and optionally whether a specified DKIM selector resolves — all sourced from live public DNS over HTTPS with no test emails sent.
Example use cases
Pre-send domain deliverability audit
“Before we send our newsletter campaign to these addresses, can you check whether paypal.com has MX, SPF, and DMARC records set up so I know the domain is technically configured to receive email?”
Investigating suspicious sender domain
“I got an email from someone claiming to be at acme-invoices.net — can you check if that domain actually has proper email infrastructure like MX and SPF records, or if it looks like a throwaway domain?”
Validating own domain email config
“We just set up email for our domain startup.io — can you verify that our MX, SPF, and DMARC records are all present and check the DKIM selector 'mailgun' to confirm we're good to go?”
Technical details
Endpoint
POSThttps://api.macaroonnetwork.com/execute/email-domain-deliverability-check-v1When to prefer
Choose this endpoint when you need a fast, privacy-safe, no-side-effect check of a domain's email DNS configuration using only public DNS records. It is ideal for pre-send validation, phishing/spoofing triage, or confirming your own domain's email setup. Prefer it over email verification services when you do NOT need mailbox existence checks, leaked-email database lookups, or proprietary deliverability scoring — just clean, raw DNS signal.
Side effects
- Domain does not exist in DNS — returns negative results for all checks
- DKIM selector not provided — selector check skipped
- Public DNS resolver temporarily unavailable — request may time out or return error
- Malformed domain input — validation error returned
- DMARC record exists but is malformed — policy may be unparseable
