Identifying Amazon Buyers: How to Capture First-Party Customer Data from Amazon Sales

If you're selling products on Amazon, you're likely facing a frustrating paradox: customers are buying your products, but you don't actually know who they are. This gap in customer knowledge creates significant challenges for building long-term relationships, understanding your true customer acquisition costs, and maximizing the lifetime value of your Amazon buyers.

‍

The Amazon Data Problem

‍

Amazon's marketplace has become essential for many brands, but it comes with a major limitation: you don't get direct access to your customers' contact information.

When someone buys your product on Amazon, you have access to the following data:

• Shipping information needed to fulfill orders
• Access to communicate through Amazon's Buyer-Seller Messaging Service (using encrypted email aliases)
• Order reports, sales data, and inventory information through Seller Central

However, you lack the following data when someone buys your product on Amazon:

• Email addresses
• Phone numbers
• Any other direct customer contact details

This limitation is intentional, as Amazon’s goal is to drive consumers to continue making repeat purchases through their platform, rather than external sites.

‍

Lack of Amazon Customer Data Limits Customer Lifetime Value

Without direct customer data, brands face several critical challenges:

No direct customer relationships. You can't build a relationship with customers who remain completely anonymous, which severely limits your ability to maximize their lifetime value.

Incomplete customer journey visibility. When a customer sees your ads on social media but ultimately purchases on Amazon (often to take advantage of Prime shipping), you can't track their journey from first touchpoint to purchase. The customer remains anonymous.

Unclear attribution and ROI. If a customer buys from you once on Amazon and later purchases directly from your website or another retailer, you have no way to connect those transactions. This makes it impossible to calculate true customer acquisition costs versus lifetime value.

Limited remarketing opportunities. Without customer contact information, you can't send targeted follow-up campaigns, abandoned cart reminders, or personalized product recommendations.

Capturing Amazon Customer Data with Brij

‍

Brij enables brands to capture first-party customer data from Amazon purchases using value-driven experiences that customers actually want to engage with. Once captured, that data flows directly into your existing tech stack, powering analytics, lifecycle marketing, and smarter business decisions.

‍

How It Works

Brij's no-code platform allows you to create digital customer experiences that are presented to customers after they've made an Amazon purchase. These experiences are typically accessed through QR codes placed on product inserts or directly on product packaging.

The key is offering genuine value in exchange for customer information:

• Rebates on their purchase
• Entry into sweepstakes
• Exclusive digital content
• Free gifts (physical or digital)
• Product warranties and registrations
• Discount codes for future Amazon purchases

When customers scan the QR code and engage with your Brij experience, they voluntarily provide their contact information and opt into ongoing marketing communications from your brand.

‍

Brij's Single-Use Amazon Discount Codes

Brij offers something particularly powerful for Amazon sellers: individualized Amazon discount codes. These are unique, one-time-use codes that link back to your Amazon storefront or specific product listings.

For example, you could include a product insert with a QR code offering 20% off the customer's next Amazon purchase after they input their email or phone number. Because each code is individualized, you remain compliant with Amazon's policies while still identifying customers and driving them back to purchase more on Amazon. This feature is unique to Brij and prevents the problem of mass coupon code leaks.

Bobbie: Capturing Amazon Customer Data Through Educational Content

Bobbie sells baby formula on Amazon. They added a sticker on top of their formula canisters fulfilled via Amazon with a QR code and the call-to-action "Get Our Feeding Schedule."

The Experience: When Amazon buyers scan the QR code, they're directed to a Brij experience where they can opt into email communications from Bobbie in exchange for a helpful "Feeding Guide" sent via email. The experience also includes a post-purchase survey asking how customers first heard about Bobbie and why they chose to purchase on Amazon, plus links to Bobbie's social pages and other product offerings.

The Results:

• 21% email opt-in rate
• Approximately $150,000 in revenue generated from identified customers
• Customer data now syncs to Bobbie's Shopify store, enabling personalized remarketing campaigns (like triggering emails when customers likely need another canister of formula)
