We review publicly visible website and email configuration signals that affect availability, deliverability, and trust — using the same data relied on by browsers and email providers.
This page explains why you may have heard from us and what we look for.
We regularly visit publicly accessible websites while looking up business details or contact information.
Occasionally, we notice obvious issues that affect how a site appears, functions, or how email is delivered. When that happens, we may reach out to let the business owner know.
There is no obligation to respond, engage our services, or take any action.
Basic website accessibility, common error responses, and SSL certificate validity that may prevent visitors from accessing your site.
Public email configuration such as MX records, SPF, DKIM and DMARC, which influence whether emails reach inboxes or are flagged as spam.
High-level configuration signals that may affect how browsers, email providers, and third-party services interpret your domain.
This is not a penetration test, vulnerability scan, or internal security assessment.
We do not log in to systems, access private data, attempt authentication, or perform intrusive testing of any kind.
All observations are based entirely on publicly available information — the same data used by browsers, email providers, and search engines.
This review process is run by Technical Support AU — an Australian IT consultancy supporting small and medium businesses with websites, email systems, infrastructure, cyber security, and backup and disaster recovery.
We often help businesses understand what they actually have in place — domains, hosting, email, and related services — and whether it still makes sense for how they operate today.
Our focus is on practical, real-world issues that affect reliability, deliverability, and day-to-day operations.
If you were contacted and would like clarification, or if you’d like to ask a question about something that was mentioned, you’re welcome to email us.
