  • 'Think outside the envelope' and use the distinctive look and feel of your mailed items to get your campaign noticed
  • Gain recognition for your brand by sending out unusual items
  • Help your brand, product or promotion to really stand out in the mailbox

Impact mail is being phased out

We regularly review our products and services in line with a variety of factors including customer demand and the cost to deliver. Following a recent review, we’ve decided to end our Impact Mail service as of 6 September 2021. Impact Mail can continue to be sent until this date.

From 6 September, please select one of our other addressed bulk mail services. Please also check that your articles meet the guidelines for the service you select.

To discuss alternative options please contact your Australia Post account manager or our customer service team on 13 11 18.
