Amazon Product Inserts: Rules, Examples, and Best Practices

A small card tucked inside a package can do more work than most sellers realize. Product inserts build trust, create repeat buyers, reduce negative reviews, and give customers a direct line to your support team. Done right, they turn a one-time order into an ongoing relationship. Done wrong, they get your account flagged.

Amazon allows product inserts. Amazon also has specific rules about what those inserts can and cannot say. The gap between "allowed" and "flagged" is narrower than most sellers think.

This guide covers the rules, the opportunities, and the best practices for creating product inserts that actually perform without putting your account at risk.

What Are Amazon Product Inserts?

Product inserts are printed cards, flyers, or small booklets placed inside the product packaging before it ships to Amazon's fulfillment centers. When a customer opens the box, the insert is the first branded thing they touch after the product itself.

Most inserts are the size of a standard business card (3.5 x 2 inches) or a postcard (4 x 6 inches). Some sellers go larger, but the goal is the same: deliver a short, clear message that makes the customer's next step obvious.

What Amazon Allows on Product Inserts

Amazon's Terms of Service and review guidelines govern what can appear on inserts. The rules boil down to a few core restrictions, with everything else effectively fair game.

The distinction matters. Amazon's enforcement is automated and manual. Competitors file complaints. Customers report suspicious language. The safest inserts use plain, unbiased wording and keep the review request physically separated from any discount offer.

The Benefits of Product Packaging Inserts

Insert cards cost almost nothing to print but carry outsized impact on three fronts: review generation, customer service deflection, and lifetime value.

1. Proactive Customer Service

Most dissatisfied customers go straight to a one-star review. They don't look for your email address. They don't call. An insert that says "Having trouble? Contact us at support@yourbrand.com and we'll make it right" gives them a path that doesn't start with a public complaint.

This alone can reduce negative review velocity. The customer still gets heard. You get a chance to fix the issue before it becomes permanent. And if you resolve it well, they may update or remove the original review.

2. Neutral Review Requests

You're allowed to ask for feedback. You're not allowed to steer it. The safest phrasing is something like: "We'd appreciate hearing your feedback." No qualifiers. No emotional language. No implied expectation.

Include simple instructions on how to leave a review. Most first-time Amazon buyers don't know how. A two-step visual (go to Your Orders → Write a Product Review) removes friction.

3. Repeat Purchase Incentives

A discount code for your Amazon store is a legitimate, effective tool. It drives customers back to your storefront instead of letting them drift to a competitor on their next order. The code must be exclusive to your Amazon store and physically separated from any review language on the insert.

Place the discount on the back of the card. Place the review request on the front. Or use two separate cards. Physical separation eliminates any appearance of incentivizing reviews.

4. Brand Building and Cross-Selling

Inserts are one of the few places on Amazon where you control the brand experience. Your logo, your colors, your voice. Use the real estate to introduce the customer to other products in your catalog that complement what they just bought.

Amazon Product Insert Best Practices

Size and Format

Business-card size (3.5 × 2 inches) works for simple thank-you messages and review requests. If you need space for setup instructions, care tips, or a cross-sell section, go postcard (4 × 6 inches). Keep it small enough that a customer can hold onto it or pin it to a fridge.

Design for Scannability

Nobody reads walls of text on a 3-inch card. Use your brand's primary color as an accent. Keep the font large enough to read without squinting. Structure the card in clear sections with visual separation between the thank-you, the feedback ask, and any discount offer.

Keep the Review Request Neutral

Use phrases like:

• "We would appreciate hearing your feedback!"
• "Tell us what you think."
• "Your honest review helps other customers."

Avoid words like "happy," "positive," "satisfied," "5-star," "great," or "love." Even if you don't mean it as steering, Amazon's automated systems flag emotional language near review requests.

Separate Discounts from Review Requests

If your insert includes a discount code, put it on the opposite side of the card from the review request. Better yet, use a separate card entirely. The goal is zero visual connection between "leave a review" and "here's a discount." Amazon's policy explicitly prohibits offering "a financial reward, discount, free products, or other compensation in exchange for a review."

Use a QR Code Strategically

QR codes are allowed if they point to compliant destinations. Safe targets include your Amazon Storefront, a specific product page on Amazon, or a warranty registration page. Risky targets include your own e-commerce site, an email-capture landing page, or a discount page that also mentions reviews.

Remind Customers About Warranties and Setup

If your product has a warranty, tell them how to register it. If there are setup steps that aren't obvious from the packaging, include a quick-start guide. These details reduce returns and preempt the "this doesn't work" reviews that often come from user error, not product defects.

Cross-Sell Within TOS

You're allowed to suggest other products you sell on Amazon. Feature two or three complementary items with their Amazon product names. Don't send the customer to a non-Amazon catalog. Don't link to products from other sellers. Stay in your lane.

Example 2: Dual-Card Approach

Example 3: Postcard with Setup Guide

Common Mistakes That Get Sellers Flagged

Any of these can trigger an Amazon investigation. The outcome ranges from a warning to listing suspension to full account deactivation. The policy is clear. The enforcement is real. Don't test the edges.
