Sendle's unlimited compostable satchels for sustainable and environment friendly packaging

Now, when you ship with Sendle’s totally compostable A4 satchel, there’s no weight limit. You can fill it to the brim, and we’ll ship it for the same low cost as a 500g satchel. Ship more stuff for the same low price! Books! Fishing lures! Paper weights made of Osmium! Gold bullion!

Enjoy sustainably shipping an unlimited variety of items of different weights and sizes. If you can get it to fit in the Unlimited Compostable Satchel, we’ll ship it.

Choosing to ship with Sendle’s compostable mailers is a cost-effective way for small businesses to improve their product offering to customers in two ways:

  • Customer bundles can contain more items! Holidays and occasions can be made extra special by adding personalized trinkets, greeting cards, and other meaningful items that customers will surely love. Whatever it is, our postage satchels are durable enough to handle all the love. Invest in wonderful unboxing experiences for your customers.
  • Small businesses can opt to sell bigger items without added postage costs. This could mean selling new lines of bigger shampoo bars, thicker knitted tops, more chocolate variety, and so much more! Small business owners could diversify their offerings and attract more customers in the long run by posting with the Unlimited Compostable Satchel.

And that’s why size matters. Speaking of sizes, we’ve also added a new feature on the Sendle dashboard: Saved sizes! Now, your parcel size preferences can be saved so you can spend less time configuring and more time shipping.

Send parcels for as low as $4.98 (excl. GST)

The Unlimited Compostable Satchel is designed to make your money stretch further and takes the guesswork out of postage.

How to pack your items for shipping in four steps

Our postage satchels are built to be durable, but not invincible. So follow these guidelines to make sure your goods arrive safe and sound.

Sendle's unlimited compostable satchels for sustainable and environment friendly packaging

  1. Double bag or box your products. Place one container inside another with cushioning material (such as scrunched up newspaper) in between the two. It might feel like overkill, but snug parcels will make your customers happy!
  2. Just like trousers and turkeys, overstuffing can cause all kinds of awkward breakages. So take care when packing your satchel.
  3. Firmly seal your satchel shut, and use extra tape if needed.
  4. Don't substitute secure packaging for 'fragile' or 'handle with care' stickers. Machines can't read these stickers (not yet, anyway…).

Check out Sendle’s comprehensive packaging guidelines for the complete rundown.


The Unlimited Compostable Satchel is only available in A4 satchel size. Of course you can use your own packaging, or a box, but our regular 500g pricing will still apply.

Luckily, our Price Guarantee means you’ll save on delivery when compared to Standard Parcel Post rates.

Is there anything else I need to know about the Unlimited Satchel?

As with all shipping services, if you’re interested in using our compostable mailers it’s best to know the available pickup locations and packing requirements. The Unlimited Compostable Satchel is only available for domestic delivery. Please visit our Help Centre to learn more.


The problem with plastic mailers

More than 1 billion parcels are being delivered per year; and 131.2 billion globally. Now imagine if all of those packages were made up of plastics–plastic packaging, plastic fillers, plastic labels, and plastic wrapping for the product inside. Australians produce 540kg of household waste per person, that’s landfills worth of garbage each year. And in other countries, it gets worse. These landfills are what’s really unlimited here. Plastics stay around for thousands of years, that’s centuries after you’ve mindlessly discarded that bubblewrap. 

However, we aren’t finding new places to throw away these plastics. They end up in oceans and huge plots of land around the world. The largest rubbish tip in Australia is a very deep hole, 150 metres deep and expectedly, it will hold around 12.5 million cubic metres of waste in the next 20 years. Although there are recycling efforts, it’s not enough to lower the demand for more landfills with the amount of rubbish being produced globally. By choosing plastic, we are making less and less space for both animals and people. Imagine losing your home to make way for plastics! 

This grim truth is the reason why Sendle is committed to raising awareness and  providing opportunities for small businesses like yours to make the simple yet impactful switch to compostable mailers. We are proud to be a part of the solution, and so can you! Choose biodegradable or compostable packaging. Choose Sendle: sustainable shipping that’s good for the world.
