How to Use Self-Mailers

Self-mailers are designed for ease of use. Begin by choosing the right size to fit your items securely. Pack your items snugly to prevent movement during transit, which helps protect them from damage.

After packing, seal the self-mailer securely with the adhesive strip on the flap. Clearly address the mailer, including the recipient’s name and complete address. Once addressed, continue by dropping off the mailer at your local post office or designated mailing spot. These simple steps help ensure your items are well-protected and reach their destination without issues.

Customization Options

A standout feature of Australia Post self-mailers is the customization option.

Protecting Your Items

Ensuring your items arrive in perfect condition during transit is crucial. Choose snug-fitting packaging to prevent movement and use heavy-duty tape for extra protection. Making the right choice in packaging materials can significantly impact the safety of your things.

For fragile items, use rigid mailers to prevent bending and fill empty spaces with void fillers like shredded paper. Local post office staff can offer personalized advice on the best packaging options for your needs. Self-mailers must also be securely fastened to prevent them from opening during transit, and Australia Post discourages the use of staples or metal fasteners for this purpose. Proper packaging is essential to avoid damage during transit.
