Australian business email hosting and messaging, properly managed.

Business email hosting with Cloud365 means your email data stays in Australian data centres, managed by a team operating under confidentiality agreements. We don't scan your email to sell advertising. We don't route your communications through overseas servers. Your business email is your business.

We provide hosted Microsoft Exchange and compatible business email services, configured and managed by our team. Spam filtering is included — not as a token blocklist filter, but as a properly configured, continuously updated enterprise-grade filtering system that blocks threats without burying legitimate mail in false positives.

Spam filtering is not a solved problem — threat actors continuously evolve their techniques, and a filtering system that was effective six months ago may have significant gaps today. Cloud365 operates enterprise-grade spam and threat filtering as a continuously updated service, not a set-and-forget blocklist.

Our filtering service works for both inbound mail — protecting your staff from spam, phishing, malware and business email compromise — and outbound mail — ensuring your legitimate email doesn't end up blacklisted due to other users' behaviour on a shared platform.

Applications that send email — order confirmations, notifications, system alerts, reports — need a reliable path to deliver those messages. Sending directly from a server is unreliable: IP reputation, SPF records and blacklisting all affect deliverability. A properly configured mail relay ensures your application's email actually reaches recipients.

Cloud365 provides managed mail relay as part of every managed service — your hosted application sends through our relay infrastructure, which is properly configured with authentication, IP reputation management, and delivery monitoring. If your application's email isn't reaching recipients, we investigate it.
