What you need to know
- The market has three layers: national networks (IVE Group, Australia Post), specialist local distributors, and tracked-and-attributed providers.
- National networks offer scale and breadth; specialist distributors offer suburb-level flexibility through local walkers.
- Delivery accountability is difficult to compare. Ask each provider to state its oversight, evidence and exclusions in writing.
- Delivery oversight and response measurement answer different questions and should not be presented as the same proof.
- When call tracking is included, a campaign number can measure calls made to that number. Area-level comparison needs an agreed measurement structure.
Search “letterbox distribution companies” in Australia and you get providers that operate in fundamentally different ways: a national marketing conglomerate, the postal network, and a long tail of local distributors, all described with the same few words. Comparing them on price per thousand alone misses what actually separates them. This is a neutral market map, not a ranking and not a hit piece, written to sort the category so your comparison is like for like.
Method
The classifications and quotations below are drawn from each provider's own public website as of June 2026, and characterise the position each takes in its own words. No third-party pricing is asserted, because letterbox pricing is quoted per campaign and varies by format, area and volume; confirm current pricing with each provider. Gibson Promotions is included as one option and is the publisher of this analysis, which is disclosed rather than hidden. Sources are listed at the end.
Finding: three layers, not one list
1. National networks
These providers compete on scale and breadth of service.
- IVE Group describes itself as “Australia's largest diversified marketing company,” with the line “one partner, infinite possibilities,” guiding clients “from idea to execution.” It is the large-scale, full-service end of the market, with distribution one part of a broad offering.
- Australia Post offers unaddressed mail across its national delivery network, the established option for broad national or regional reach. (We could not load Australia Post's specific unaddressed-mail page at the time of writing; see its business marketing section for current detail.)
2. Specialist distributors
These are focused distribution operators, frequently Sydney-centric, using local walkers and competing on flexibility and local knowledge.
- Letterbox Distribution Services describes “flyer drops Australia-wide with local walkers, shared drops, express flyer drops, letterbox distribution and printing.”
- Leaflet Distribution Sydney describes a “GPS tracked, reliable and cost effective guaranteed leaflet distribution service throughout Sydney,” which is notable because it puts tracking front and centre.
- Australian Postal and Flyer Distribution positions around flyer distribution, printing and reliable letterbox drops in Sydney.
- Letterbox Distribution Sydney describes itself as “a leading letterbox distribution company in Sydney.”
The hardest thing to verify in letterbox distribution is the one thing you are paying for: that your flyers actually reached letterboxes. That is why accountability, not price per thousand, is the real axis of comparison.
3. Distribution with optional response attribution
The third layer separates two questions: how the provider oversees the physical distribution, and how the customer will measure enquiries. Gibson's standard letterbox distribution uses start and finish emails from a regional supervisor, supervisor spot checks and delivery inspection photos on request. When Gibson call tracking is also included, a campaign number can report calls made to that number. It does not prove physical delivery, and one number does not identify the caller's suburb. See how to plan letterbox response measurement.
Discussion: how to actually choose
Decide on two axes before you compare quotes. First, coverage: national reach (a network) versus suburb-level precision (a specialist). Second, accountability: how will you know the drop happened, and how will you know what it produced. Price per thousand only becomes meaningful once those two are settled, because the cheapest drop that you cannot verify and cannot measure is not actually the cheapest. If you run other channels too, the ability to see a flyer campaign and a Google Ads campaign on one dashboard is worth more than a small difference in CPM. Our guide on what letterbox distribution costs in Sydney covers the pricing detail once you have chosen a layer.
Limitations
This is a point-in-time reading of public websites in June 2026 and classifies providers by how they describe themselves. Providers offer overlapping services, coverage and pricing change, and one page (Australia Post's unaddressed-mail page) could not be loaded at the time of writing. Treat this as a map of the territory, not a substitute for quotes against your own suburbs and volumes.

Frequently asked questions
Who are the main letterbox and flyer distribution companies in Australia?
The market has three layers. National networks include IVE Group (which describes itself as Australia's largest diversified marketing company) and Australia Post, which offers unaddressed mail across its national delivery network. Specialist distributors, often Sydney-focused, include operators like Australian Postal and Flyer Distribution, Letterbox Distribution Services and Leaflet Distribution Sydney. The third layer is tracked-and-attributed providers that tie the drop to the phone calls it generates. Which suits you depends on coverage, accountability and whether you need to measure the response.
How do letterbox distribution companies charge?
Most price per thousand items delivered (a CPM), with the rate varying by format (DL flyer versus A4), by area (inner versus outer suburbs), and by whether you book a solo drop or a shared drop where your flyer goes out alongside others. Few publish fixed prices because campaigns vary; you request a quote for your suburbs and volume. Always confirm what verification, if any, is included in the price.
How do I know my flyers were actually delivered?
Ask each provider to state its delivery oversight, evidence, exclusions and client updates in writing. Providers use different methods. Gibson uses start and finish emails from a regional supervisor, supervisor spot checks and delivery inspection photos on request. Response tracking is separate and does not prove physical delivery.
Letterbox distribution or Australia Post unaddressed mail: which is better?
Australia Post unaddressed mail uses the national postal network and suits broad national or regional reach. Specialist letterbox distributors use local walkers and can be more flexible on suburb-level targeting and timing. Neither is better in the abstract; the deciding factors are your targeting precision, budget per thousand, and how much delivery accountability you need.
How do I measure ROI on a letterbox drop?
Agree the response path before printing. When call tracking is included, a campaign number can attribute calls made to that number to the campaign. A single number measures the whole drop, not each suburb. Area comparisons require a separate number, artwork, landing-page or distribution-wave structure agreed in advance.
