Envelope layout standards
See our envelope layout requirements for machinable or manually-sorted Bulk Mail.
When sending bulk business mail, your items must comply with our layout standards to ensure they are processed with maximum efficiency.
Our Envelope Layout Standards (PDF - 5.6MB) outline our requirements for both machinable Bulk Mail products (VolumePost 1, VolumePost 3, Business Standard and Approved FreePost) and manually sorted Bulk Mail products (GoFlexible, Business Flexible and PrintPost).
We’ve recently made changes to our maximum weight and minimum delivery address font size for VolumePost 1 and VolumePost 3.
For more information and assistance with your envelope layout, contact our National Contact Centre or phone your account manager direct.
