Know exactly what the internet sees when it looks at your domain.
DNS, email authentication, blacklists, SSL and uptime — checked in seconds, monitored around the clock, explained in plain language.
mx:example.comblacklist:8.8.8.8dmarc:example.comspf:example.comhealth:example.comssl:example.comThe complete toolkit for domains that must work
From a quick MX lookup to a full scored health report — the same engine powers our free tools, the monitoring platform and the API.
Email authentication
SPF, DKIM, DMARC, BIMI, MTA-STS and TLS-RPT — validated against the RFCs and explained in plain language, with generators to fix what is missing.
Blacklist intelligence
Every MX and sending IP checked against 60+ DNS blacklists in parallel, with delisting links and instant alerts the moment you get listed.
Authoritative DNS
We ask your name servers directly, so changes show up immediately. Propagation across 12 global resolvers, DNSSEC validation and delegation checks.
Scored health reports
Over 100 checks across DNS, mail, web, reputation and registration rolled into one score, with problems ranked by impact.
Alerts that matter
Domain and certificate expiry countdowns, DNS change detection, blacklist listings, mail-server outages — by email, webhook or Slack.
API-first
Every tool is a JSON endpoint. Integrate lookups into your onboarding, ticketing or provisioning flows in minutes.
Stop finding out from your customers
Add a domain and StatusDNS re-checks it around the clock. A mail server drops off a blacklist at 3 am? You know at 3:05. A certificate has 14 days left? You know today.
- Blacklist listings and delistings
- Domain & SSL expiry countdowns (60 / 30 / 14 / 7 / 3 / 1 days)
- NS, MX, SPF, DMARC and DKIM changes
- Website uptime and mail-server availability
- Weekly health digest for every domain
