Email Auth Checker
Check SPF, DKIM, DMARC, and MX records for a domain.
Email DNS checks without a cluttered dashboard.
Email Auth Checker is designed for practical verification rather than scorecards. Paste a domain, optionally provide a DKIM selector, and review what DNS is really publishing for SPF, DMARC, DKIM, and mail routing.
It is useful for onboarding new sending domains, checking client records, or validating whether mail authentication changes actually propagated.

Check SPF, DKIM, DMARC, and MX records for a sending domain.
Yes. The checker probes a small list of common selectors and also accepts a custom selector if you already know the provider naming pattern.
No. It verifies DNS authentication and routing signals, not downstream deliverability outcomes.
