Packaging Inserts Types Benefits and How to Use Them

A packaging insert is any printed or physical item placed inside a box as part of your eCommerce packaging, designed to communicate with the customer or encourage further action. Unlike structural inserts such as foam or molded pulp, which exist solely to protect the product during transit, the inserts covered in this guide serve as marketing and communication tools. They live in the same box, but their job is to speak directly to the customer, whether that means saying thank you, offering a discount, or explaining how to use what they just bought. 

Packaging inserts matter because the unboxing moment is one of the few remaining touchpoints where a brand has a customer's full, undivided attention. There is no scrolling away, no competing tab, and no distraction. According toShopify's guide to packaging inserts, even a simple discount offer placed directly in a box tends to get noticed far more reliably than the same offer sent by email, since it lands in the customer's hands rather than their spam folder.

For small and growing brands in particular, inserts are a low-cost way to compete with much larger retailers in the customer experience. A well-designed insert can increase repeat purchases, generate reviews, and turn a single sale into an ongoing relationship, all without adding meaningfully to your packaging budget. Because inserts print flat and ship inside the boxes you are already sending, the added cost per unit is often just a few cents, while the potential upside in retention and word-of-mouth is far greater.

Each insert type serves a different goal, so choosing the right one starts with knowing what you want the customer to feel or do next.

1. Thank You Cards

A thank-you card is the simplest insert to produce and often has the highest impact. It works best for brands that want to build an emotional connection quickly, particularly small businesses where a personal touch is part of the brand story.

2. Discount Codes and Offers

A discount code inside the box gives customers a tangible reason to come back. This insert type works best for brands with repeat-purchase potential, such as consumables, beauty products, or apparel, where a second purchase is a realistic near-term goal.

3. Product Information Cards

A product information card explains what the item is made of, how it was sourced or what makes it different from competitors. This is most useful for brands selling something that benefits from a bit of context, such as handmade goods, specialty foods or products with a sustainability story worth telling.

4. Promotional Inserts

Promotional inserts point customers toward something beyond the current purchase, such as a referral program, a social media hashtag, or a related product line. These work best for brands actively trying to grow their audience or community, rather than simply completing a transaction.

5. Samples or Freebies

Including a small sample of another product gives customers a reason to explore more of your catalog. This insert type is best suited to brands with multiple products at a similar price point, since it turns one purchase into a preview of another.

For example, a skincare brand might include a sample of a complementary product alongside a thank-you card, giving customers a low-risk way to try something new. This not only increases the chances of a second purchase but also helps customers explore more of the product range without additional marketing effort.

6. Instruction or Care Guides

An instruction or care guide helps customers get the most out of what they bought and reduces returns caused by misuse. This is essential for anything with a learning curve, such as skincare, electronic accessories, or assembly-required items.

Packaging inserts make the most sense when a brand has a specific goal beyond simply shipping a product safely, rather than being added as a default habit on every order. The right moments to use them include:

• You want to encourage a second purchase, such as through a discount code or loyalty offer
• Your product benefits from added context that a label alone cannot cover, like sourcing or usage details
• You want to prompt customers to leave a review or share their purchase
• You are building a recognizable brand identity around the unboxing experience itself
• The order is a first-time customer purchase, a seasonal launch or a subscription box, since customers are already primed to pay attention to what arrives inside

If you already ship your products incustom mailer boxes, inserts are a natural next step since the packaging experience is already part of your brand strategy.

Inserts are not automatically worth adding to every shipment, and there are a few situations where skipping them is the smarter call:

• Margins are thin on a specific product line, so the added printing cost is hard to justify
• The purchase is a one-time transaction, where a discount code will rarely get used before it expires
• You are already including several inserts, since stacking too many at once dilutes the message and makes the unboxing feel cluttered rather than considered
• The product ships in bulk or business-to-business orders, where individual unboxing moments matter less than cost per unit

In these cases, a single well-designed insert will always outperform five competing ones.

Start with the outcome you want. If retention is the priority, a discount code or loyalty offer makes sense. If brand storytelling matters more, a product information card or a thank-you note does more work. If reducing returns is the goal, an instruction guide should take priority over anything promotional. Matching the insert to the specific business goal, rather than defaulting to whatever looks nicest, is what separates inserts that perform from ones that simply add cost.

A few practical guidelines keep inserts effective, whether you are printing your first thank-you card or refining an existing insert program:

• Keep the message short enough to read in under ten seconds
• Use consistent colors and fonts that match the rest of your packaging
• Make any offer or code easy to find, not buried in paragraph text
• Print on quality stock, since a flimsy card can undercut a premium product
• Give each insert a single clear purpose rather than combining several messages on one card
• Test a small run before committing to a full print order

CEF Box offers custompackaging inserts built to fit your exact product and box size, along with sample services so you can hold a physical proof before placing a larger order.

Packaging inserts may be small, but their impact on customer experience and retention can be significant. When used intentionally, they become more than just an extra item in a box. They become a direct line between your brand and your customer.

The most effective inserts are not the most complex, but the most purposeful. By choosing the right type, keeping the message clear, and aligning inserts with your business goals, you can turn a single delivery into an opportunity for long-term growth.
