Check DNS records, nameservers, email authentication, MX configuration and SSL health in one report.
DNS and email diagnostics
Inspect DNS records, nameservers, MX routing, SPF, DMARC, discoverable DKIM, HTTPS and certificate health.
Diagnostic only. Private networks and unsafe destinations are blocked. This checker cannot edit DNS or guarantee mail delivery.
Domain check in progress
Reading bounded public DNS, web and certificate evidence.

Next step, if you want one
The report above is generated. These are not — each one is work done by hand on the findings you just produced. Scope is agreed before anything is payable.
From
A prioritised remediation plan, reviewed by hand, built on a report you already have.
From
One domain and one email provider: supported MX, SPF, DKIM and DMARC review and configuration.
Nothing is charged automatically and no card is stored. The free tools stay free and complete — this is extra work on top, never a feature taken out of them.
If you would rather not do this yourself
Websites, CRM systems and the APIs that join them. The work is done remotely as a matter of course — past clients have been in Australia, Belgium and the UAE — and the scope is agreed and the quote fixed before anything is payable.
It looks like you are in the UAE
Websites, CRM systems and the APIs that join them, for businesses across the Emirates. WhatsApp is the fastest way to reach me, quotes and invoices are issued in AED, and meeting in person is possible when it helps. Scope is agreed and the quote fixed before anything is payable.

How the domain check works
The checker accepts a bare domain or HTTP/HTTPS address, removes website-only parts and rejects private, internal or malformed targets.
DNS records, mail authentication, MX targets, HTTP routing and the public TLS certificate are inspected without logging in or changing anything.
DNS, email authentication, mail routing and website/SSL use transparent rules. A domain with no mail service is not unfairly penalized for missing mail records.
DKIM selectors cannot be exhaustively discovered from public DNS. The checker tests your supplied selector plus a small common set. Public records also cannot prove inbox placement, message signing in practice or provider-side delivery behavior.
Use only public destinations you are authorized to check. By using this tool, you agree to the Terms of Use.
