Get started using Clean Mail

Posting your mail

Using our Clean Mail Bulk Delivery service is as easy as 1, 2, 3.

You do not need to apply for the Clean Mail service.

  1. Prepare your mail: You or your mail house needs to prepare your Clean Mail articles ensuring that they are type/machine addressed (if you need a mail house to help you, check out our list of Bulk Mail Partners). Refer to the Clean Mail Service Guide (1.30mb) for detailed instructions on how to prepare and sort your Clean Mail articles.
  2. Complete your lodgement documentation:  Complete the Clean Mail lodgement document (108kb), or if you're paying using a postage meter, complete the Metered lodgement document (120kb)
  3. Lodge your mail: Take your completed document, with your articles, to your closest approved lodgement facility*, or your mail house may use the Electronic Lodgement Management System (eLMS) and arrange for your items to be collected instead.
