Trusted by top companies worldwide
Track SPF, DKIM, DMARC, MX, and domain-auth drift
Use recurring checks to catch policy changes, broken include chains, selector issues, and routing drift before they degrade delivery quality.
Run on-demand validation after DNS, provider, or campaign changes
Rerun checks immediately after DNS edits, provider cutovers, deployments, and high-value send preparation so risky drift is caught earlier.
