Print inside the parcel
Every order you ship has room for printed material, and most brands fill it without a clear view of what each piece does. Some inserts genuinely drive repeat purchase, reduce support contacts, or make a product work. Others are there because they have always been there, costing money per order and going straight in the recycling. Here is how to tell them apart.
The economics of a per-order insert
An insert costs pennies. That framing is what makes inserts easy to add and hard to evaluate, because pennies multiplied by your order volume is a real number, and it recurs forever.
A piece costing eight cents across 4,000 orders a month is $320 a month, roughly $3,840 a year. That is a defensible spend for something that measurably drives repeat purchase, and pure waste for something nobody reads. The problem is that most brands never determine which they have.
There is a second cost that gets missed: insertion is a pick. Every distinct item added to an order is a handling step at the pack bench, with a small time cost and a small error opportunity. Four separate inserts is four steps. Consolidating them onto one printed piece is cheaper twice over, in material and in labour.
The test for any insert: what does it do, and how would you know if it stopped working? If you cannot answer the second question, you cannot manage the spend, and you probably cannot justify it either.
The four jobs an insert can do
1. Make the product work
Instructions, assembly guides, sizing charts, care instructions, safety information, quick-start cards. This category is the easiest to justify because it has a measurable effect on support volume and returns.
The connection to returns is worth making explicit. A meaningful share of returns are information failures rather than product failures: the customer could not work out how to use it, or did not understand what they had. Given that returns run roughly 19% to 20% of online orders and cost $25 to $30 each to process, a printed piece that prevents even a small fraction of them is doing serious work. Our note on return economics has the full arithmetic.
2. Drive the next purchase
Discount codes, referral cards, catalogs, and cross-sell cards for complementary products. This category can perform very well and is also where most of the waste lives, because the difference between a good and a bad version is large and only visible if you measure.
Measurement is not optional here and it is not hard: a unique code per campaign, per segment, or per recipient tells you exactly what an insert produced. Variable data printing makes per-recipient codes practical in a single run, which turns "we think inserts help" into a number.
3. Build the relationship
Thank-you cards, brand story cards, founder notes, care-and-community messaging. Harder to measure and not therefore worthless. This is the category where judgment legitimately does some work, and also where a generic printed card adds less than brands hope. A card that says "thanks for your order" in the same tone as every other card is a cost without a benefit.
The version that works is specific: something that tells the customer something they did not know, or gives them a reason to feel they chose well.
4. Do a job the operation needs
Packing slips, return forms, and order documentation. Some of this is genuinely required, some is legacy. Worth asking whether a printed packing slip is doing anything a shipping confirmation email does not, and worth checking whether a printed return form is your actual returns process or a relic of one.
Where inserts commonly waste money
- Untracked discount codes. The same code on every insert for two years tells you nothing about which insert, campaign, or segment worked.
- Dated content on undated runs. A seasonal promotion still going out in March because the box of inserts has not run down. If a piece has a date, its quantity should be set by the date, not by the price break.
- Four pieces doing one job. Consolidate. One well-designed piece beats four thin ones on material cost, insertion labour, and the customer's attention.
- Catalogs to the wrong recipients. A full catalog is one of the most expensive inserts. Sending it to every order, including small replenishment orders from subscribers who buy the same thing monthly, is where the cost concentrates.
- Inserts that outlive the offer. A code for a product you discontinued creates a support contact, which is worse than sending nothing.
Segmentation, which is the answer to most of this
The instinct with inserts is a single decision applied to every order. Nearly always, different orders deserve different treatment, and the rules are simple enough to apply reliably.
First order versus repeat. A first-time customer benefits from brand story, product education, and a reason to come back. A subscriber on their ninth identical replenishment needs none of it and may be mildly irritated by all of it.
Order value. A premium presentation on a high-value order is proportionate. The same on a low-value order can cost a meaningful share of the margin.
Product category. Care instructions belong with the products that need care, not in every parcel.
Gift orders. These want different treatment on almost every dimension, and they are usually identifiable from the order data.
These are rules, and rules belong in the system rather than in a training document. Custom kitting and packing logic gets built to your workflow by our engineers, which means "catalog only on first orders over $75" is a rule applied consistently rather than a judgment made under time pressure at a pack bench.
The quantity trap, specifically
Inserts are the product category where over-printing does the most damage, for a structural reason: they are cheap per unit, so the quantity break looks irresistible, and their content is frequently dated, so the shelf life is short.
Print 50,000 inserts carrying a promotion that changes quarterly and you have bought three quarters of waste at an excellent unit price. The framework in print quantity as an inventory decision applies with particular force: work out consumption before the content changes, and set quantity from that rather than from the price break.
Where an insert genuinely has no expiry, such as a care card for a product you will sell for years, printing deep is correct. Separating the evergreen pieces from the dated ones is the single most useful thing you can do to your insert program.
Producing them where they get used
Inserts are consumed by the fulfillment operation, so producing them in the building where orders are packed removes a freight leg and a receiving event on an item that exists only to be inserted. It also means a rule change and a print run can happen together: if the promotion changes, a short run of the new insert can be produced and swapped in without freighting anything.
That is the most direct version of the argument in print and fulfillment under one roof, and inserts are where it is least arguable.
The bottom line
Inserts do four jobs: make the product work, drive the next purchase, build the relationship, or serve the operation. Every piece in your parcel should be doing one of them identifiably, and the ones in category two should carry a trackable code so you know whether they work.
Consolidate what you can, segment by order type, and set quantity from content shelf life rather than from the price break. Then check what the pieces you have been shipping for three years are actually doing.
