How Do I Measure Whether My Package Inserts Are Working?

By Insertly Sep 23, 2026 · Updated Sep 23, 2026 11 min read

Quick answer: You measure whether package inserts are working by tying each insert to one clear action and then counting how often that action happens after orders ship. The most useful package insert metrics are QR scans, review submissions, newsletter signups, care-guide visits, discount redemptions, and repeat orders linked to a specific card or code. For a small brand, the simplest method is to compare a batch of shipped orders against the number of tracked actions from that same batch and review the results on a set schedule.

How to Tell If Your Package Inserts Are Working

A package insert is working when it gets customers to do something you can count. That action could be scanning a QR code, leaving a review, joining your email list, reading a care guide, or placing another order.

That sounds obvious, but this is where a lot of brands get fuzzy. A card can look beautiful in the box and still do nothing for the business. If you sell on OpoShop, the useful question is not "Did customers see the card?" The useful question is "What happened after the card went in the box?"

For most OpoShop merchants, the cleanest measurement setup is simple: one insert, one goal, one trackable path, one test window.

What Does It Mean for a Package Insert to 'Work'?

For a small ecommerce brand, a package insert works when it causes a clear post-purchase action. Nice design is a bonus. Action is the job.

A thank-you card that sends buyers nowhere is hard to judge. A thank-you card with a QR code that leads to a review page or reorder offer is measurable. That difference matters.

Here is the simplest way to think about it:

A review card works if reviews go up from the orders that received it.
A reorder card works if buyers come back and use the offer.
A care card works if customers visit the care guide and use it.
A newsletter card works if signups happen from shipped orders.

For brands on OpoShop, this is good news. You do not need a big analytics stack to start. You just need a way to connect the card in the box to the action after delivery.

Why Measuring Insert Performance Matters

Measuring insert performance tells you if your print cost and packing time are earning their place. Guessing does not.

A lot of small brands keep inserts because they feel thoughtful. And they can be thoughtful. But if the goal is more reviews and more repeat purchases without spending more on ads, feeling is not enough.

Measurement also helps you avoid the wrong lesson. If repeat orders go up in a busy month, the insert may deserve credit, or your seasonal demand may have changed, or your email campaign may have done the lifting. Without a simple tracking method, all three look the same.

This matters even more if you pack orders yourself. A one-to-ten person team already has enough to do. Every extra card, print run, and packing step should have a reason.

If you want inserts that are easier to measure, use print-ready cards with trackable QR destinations and order-based personalisation.

How to Measure Whether Your Package Inserts Are Working

The best way to measure whether your package inserts are working is to set one goal, attach one trackable action to that goal, and compare shipped orders with completed actions from the same date range.

Pick one goal

Choose one outcome for each card: reviews, reorders, newsletter signups, or care-guide visits.

Create one trackable path

Use one QR code, one discount code, or one landing page tied to that insert only.

Set a test window

Run the insert for a clear batch of orders, such as one week, two weeks, or one full product drop.

Count shipped orders

Record how many orders received that exact insert during the test period.

Count completed actions

Track scans, submissions, signups, or redemptions that came from that insert path.

Review on a schedule

Check results after the same delay each time so you are comparing like with like.

A simple formula helps:

Insert response rate = tracked actions / shipped orders with that insert

If 200 orders shipped with a review card and 18 buyers left a review through that card's QR path, the response rate is 18 divided by 200. That does not tell you everything, but it tells you something real.

Completed actions matter more than raw scans. A scan is interest. A review submission, signup, or redeemed offer is the result you actually wanted.

That said, scans still help. If a card gets plenty of scans but very few completed actions, the insert may be fine and the destination page may be the problem. If a card gets almost no scans, the card itself may need work.

A simple batch method for small brands

A lot of OpoShop merchants do not need expensive software for this. A spreadsheet is enough.

Use one row for each insert test:

date range shipped
insert type
goal
orders shipped
QR scans
completed actions
notes on any changes

That gives you a clean way to compare one batch against the next in your OpoShop store.

Best Ways to Track Insert Performance by Goal

Different insert goals need different tracking methods. Treating every scan the same hides what is actually working.

That is a big deal if your card includes up to three QR codes. One code may send buyers to a review page, one to a care guide, and one back to your store with a discount. Those are not the same action, so they should not be judged the same way.

Insert goal	What to track	Best tracking method	What success looks like
Review request	Review submissions	Unique QR code to review page	Reviews tied to the batch that received the card
Reorder offer	Discount redemptions and repeat orders	Insert-only discount code or QR path to a prefilled offer page	Buyers place another order using that path
Newsletter signup	Email signups	QR code to signup page made only for insert traffic	New subscribers from shipped orders
Care guide	Guide visits and time-on-page	QR code to a care or usage page	Buyers visit the guide after delivery
Thank-you card	The action attached to the card	One clear CTA only	Customers complete the one action on the card

A skincare brand may want one card focused on product usage and another focused on reviews. A candle brand may want one care card for burn instructions and a separate reorder card for the next scent. That split makes measurement cleaner.

Here is a weak setup versus a stronger one:

Weak: One thank-you card with three unrelated messages, a homepage QR code, and a general "come back soon" line. Stronger: One reorder card with one offer, one QR code, and one insert-only discount path that you can match to repeat orders.

That is the whole idea. Fewer mixed signals. Clearer numbers.

If you generate inserts from store orders, personalised PDFs can make this easier to manage at scale. A buyer name and order number on the card can help your team match what was shipped with what happened after, especially if you are testing by order batch in OpoShop.

Common Mistakes When Tracking Package Inserts

Most tracking problems come from muddy setup, not bad luck. The insert cannot prove itself if the test is messy.

The first mistake is putting too many calls to action on one card. If a buyer sees "leave a review," "join our list," and "shop again" all at once, you will get mixed behavior and fuzzy data.

The next mistake is using a link or code that appears elsewhere. If the same discount code is in your post-purchase emails and on your insert, you cannot tell what caused the order. Package inserts and post-purchase emails can work together, but they should not share the same tracking path if you want clean attribution.

Another common miss is changing too many things at once. New headline, new offer, new design, new QR destination. Then the numbers move and you still do not know why.

And a lot of brands judge too early. A card placed in today's orders may not lead to action until the package arrives, gets opened, and sits on a counter for a few days. For many OpoShop merchants, a fair test period starts after delivery and runs long enough for buyers to act.

A practical rhythm is this:

fast actions like QR scans or care-guide visits: review within days of delivery
reviews: review after buyers have had time to try the product
reorders: review over a longer window, since customers need time to use the product first

The best starting point for a small brand is one insert goal, one QR destination, and one reporting sheet. Keep it boring at first. Boring is easier to measure.

If you run your store on OpoShop, start with the insert that is closest to money or proof. For some brands that is a review request. For others it is a reorder offer. Pick one.

Then test one thing at a time across a date range of orders. Handmade sellers and print-on-demand brands are in a good position here because they often control packing in-house. That makes it easier to keep the test clean.

A simple first test could look like this:

14 days of shipped orders
one reorder card
one QR code to one offer page
one insert-only discount code
one spreadsheet with shipped orders, scans, redemptions, and repeat orders

That is enough to learn something useful. You do not need fancy software before you have a clean habit.

If you want a simpler way to create branded inserts tied to real order batches, start with cards that are already print-ready and built around trackable destinations.

Create trackable cards

Best answer: Start small and measure one outcome at a time. For most small ecommerce brands, the cleanest setup is one insert, one goal, one QR path, and one review window tied to shipped orders from your OpoShop store. Once that setup is working, then add more tests.

FAQs

What metrics matter most when measuring package inserts?

The metrics that matter most are completed actions tied to the insert's goal. For most brands, that means review submissions, discount redemptions, repeat orders, newsletter signups, and care-guide visits. QR scans are useful too, but scans alone are not the finish line.

How long should I test a package insert before changing it?

Test a package insert long enough for customers to receive the order and act on the card. A good test period is usually one clear batch of orders plus a follow-up window that fits the goal, with reorders needing more time than scans or page visits.

Should I use a different QR code or discount code for each insert type?

Yes. A different QR code or discount code for each insert type makes attribution much cleaner. If two cards share the same path, you lose the ability to tell which message or offer actually worked.

How do I know whether reviews came from my insert?

The cleanest method is to send insert traffic to a review page through a QR code used only on that card. If review requests also go out by email, use a separate path for the email so your insert results stay visible.

Can small ecommerce brands track insert performance manually?

Yes. A small ecommerce brand can track insert performance manually with a spreadsheet, a unique QR code, and a date range of shipped orders. That setup is often enough for founders who pack their own orders and want a clear read before adding more tools.

What is the biggest mistake when measuring package insert results?

The biggest mistake is trying to measure a card that asks buyers to do too many things at once. One card with one goal gives you cleaner behavior and cleaner numbers.

Summary: A Good Insert Is One You Can Track

A good package insert is not the one that looks nicest in the box. A good package insert is the one you can connect to a real customer action.

That is the frame we would use every time. Pick one goal. Give that goal one trackable path. Compare shipped orders with what happened next.

If you do that, your inserts stop being a nice extra and start becoming something you can actually judge. That is where better review cards, better reorder offers, and better retention work begin.

Create branded package inserts you can actually track, from review requests to reorder offers, and generate them from your store orders.
