Know what your domain is telling the world.

Inspect public email DNS records together. See the evidence, understand the gaps, and leave with a practical next step.

What this tool checks

A domain audit fetches MX, SPF and DMARC records and probes common DKIM selectors. Results are a current DNS snapshot, with records, timestamps and clear limits.

Receive mail

MX records describe mail exchangers. A null MX explicitly declares no inbound mail. A domain without MX can still use its A or AAAA records as an implicit fallback.

Authorize and authenticate

SPF lists permitted sending infrastructure; DKIM publishes signing keys; DMARC expresses policy and alignment requirements. Presence alone is not a successful authentication test.

Fix the right issue

Use the individual lookup tools and generators to investigate findings. DNS failures are shown as unknown, not interpreted as a passing or failing configuration.

Frequently asked questions

Is this an inbox placement test?

No. Inbox placement also depends on real messages, sending infrastructure, recipient filters and reputation. DNS alone cannot establish it.

Why is DKIM unknown?

DKIM keys are published under selectors. A few common selector probes cannot discover every possible key. Use the DKIM lookup with the selector from a real message.

Do you evaluate inherited DMARC policies?

The current tool reports the exact-domain policy only. It does not perform the organizational-domain discovery and policy selection described in RFC 9989.
