About CheckDomainHealth
Practical domain, email, SSL and website health checks
CheckDomainHealth helps website owners, developers and support teams check DNS, email authentication, SSL, reputation, website status and hosting signals — and understand what to fix next.
Free tools, practical guides and one clear help path for common technical domain issues.
Technical domain issues are rarely isolated
A delivery problem may involve SPF, DKIM, DMARC, MX records, reverse DNS or blacklist reputation. A website problem may involve DNS, SSL, redirects, hosting, CDN settings or CMS configuration. CheckDomainHealth was built to make these layers easier to check together.
- Email issue can involve DNS, authentication, reputation
- Website issue can involve DNS, SSL, redirects, hosting
- Migration issue can involve TTL, MX, SSL, redirects
One symptom can have several technical causes.
Why CheckDomainHealth exists
Many domain issues are difficult to diagnose because they involve several layers at once: DNS records, nameservers, email authentication, SSL certificates, hosting configuration, redirects, blacklists and website response.
A problem may look like an email issue, but the cause can be DNS, reverse DNS, authentication or reputation. A website issue may involve SSL, redirects, CDN settings, hosting or CMS configuration.
CheckDomainHealth was created to make these checks easier to run, read and act on.

CheckDomainHealth guides are written to be clear, useful and easy to follow. The goal is to help users understand what a DNS, email, SSL, website or hosting issue means and what to check next.
Tools and guides are maintained by CheckDomainHealth and reviewed for practical accuracy.
Practical wording
Written to explain what results mean, not only display raw records.
Technical review
Content is reviewed for practical accuracy and usefulness.
Context matters
Results should be interpreted together with the actual registrar, DNS provider, hosting provider, email service, CDN and website setup.
Clear expectations
CheckDomainHealth helps identify likely issues, but some fixes depend on provider access, propagation, third-party systems or server configuration.
Email delivery
SPF, DKIM and DMARC can improve trust, but inbox placement cannot be guaranteed.
DNS changes
DNS fixes may depend on TTL, propagation, registrar settings and authoritative nameservers.
SSL certificates
SSL problems may require DNS validation, certificate renewal, hosting access or server configuration.
Website fixes
Some website issues require CMS, plugin, theme, CDN, hosting or server access.
