Welcome to construction’s only

Designed specifically for the Australian construction industry, Commnia’s Inbox takes you further than any regular mail service provider could, and helps your team communicate effectively and efficiently.


Monitor the status of your emails with in-built registers for every contractual document such as RFI’s, Delays, Variations, Extensions of Time, Transmittals and Tenders.

Document Categories

Email forms change based on the selected document category, e.g. a Delay Notice category will include delay duration and steps taken to minimise delay.


Attach hundreds of files to a single email. Choose items from the Document Register, Commnia Drive or your computer/device.

Simple Approvals

Approve or reject documents directly from the email, with approved files automatically uploaded to the Document Register. 


Reports are automatically generated by the system to help you better manage your project and company correspondence.


Access history and download tracking to keep everyone accountable. No more “I never saw the email” excuses.

Due Dates

Set due dates for days remaining and outstanding to be displayed, helping your team stay on track.

Category Changes

Change categories as your email progresses. Eg, an RFI to a Design Change to a Delay Notice.
