Investigate a specific record or review a domain's authentication setup in one place. Our checker suite now includes dedicated DMARC, SPF, DKIM, and domain health tools.
Choose the check you need
- DMARC checker: inspect your policy, reporting configuration, and record validation results.
- SPF checker: inspect authorized senders, record syntax, and DNS lookup counts.
- DKIM checker: look up a selector and inspect its public key and record parameters.
- Domain health checker: review DMARC, SPF, and DKIM together, with scores and detailed checks.
Each tool shows the DNS records behind its results, so you can work from the actual configuration when investigating a failure. Share the result link with a colleague or provider to review the same domain and parameters.
