Skysnag

Skysnag centralizes email security configuration across MTA-STS, BIMI, DMARC, and TLS-RPT protocols. The platform handles certificate provisioning, policy updates, and rejection report processing, removing the manual work of DNS maintenance. You get dashboards showing exactly which senders are authenticating correctly and where failures occur.

Tailored for organizations serious about preventing email spoofing and maintaining sender reputation. Unlike single-tool validators, Skysnag orchestrates the full stack of modern email security standards in one place. Works well at scale when you're managing domains across multiple business units.
