The bulk of finished product leaving COJO is injected into the mail stream via Australia Post. This process is called Lodgement or lodging with Australia Post. COJO has had a long association with Australia Post and this is recognised with Australia Post endorsing COJO as a Bulk Mail Partner. To achieve this status COJO must rigorously adhere to a defined standard and agreed methodologies when interfacing with Australia Post. Australia Post trucks collect mail from COJO daily, more often than not several times throughout the day.
