Domain health check
Type a domain and we run 30+ checks across DNS, email, web, TLS, network and ownership, then rank what to fix.
About the Health check
One free check of a domain’s DNS, email security (SPF, DKIM, DMARC), website, SSL certificate, network and registration, with fixes in plain English.
Every result comes in two styles: plain English for everyone, and the exact technical detail for engineers, with the raw JSON one click away.
