Your domains, watched
DNS health, email authentication, certificates and blacklists — monitored continuously, explained clearly, and alerted before they become outages. Part of The Guru Platform by Select HQ.
Get Domain GuruEverything a domain can quietly break
One expired certificate or missing DMARC record can take out your email, your website, or your reputation. Domain Guru catches it first.
DNS health & monitoring
Continuous checks on your DNS records with change detection — know when something moves before it breaks your email or website.
Email authentication
SPF, DKIM, DMARC and BIMI validated on every domain, with plain-English guidance to stop spoofing and land in the inbox.
Certificate watch
TLS certificates tracked with expiry countdowns — no more Saturday-morning 'the website says not secure' calls.
Blacklist monitoring
Your domains checked against major blocklists, with alerts the moment a listing appears and guidance to get delisted.
Registrar & expiry tracking
Registration details, auto-renew status and expiry dates in one place, whoever your domains are registered with.
Alerts that matter
Email, Slack or Teams alerts with severity, context and a recommended action — not just noise.
