Ads Data Manager Just Opened to All Advertisers. Here Is Why That Matters for Sponsored Ads.
Amazon’s Ads Data Manager has been available to larger DSP advertisers for some time. As of now, it has expanded to all advertisers globally, including small businesses, and covers all campaign types, including Sponsored Products, Sponsored Brands, and Sponsored Display.
That is a meaningful shift. First-party data targeting was previously a capability reserved for brands with the budget and technical resources to run Amazon DSP. It is now available to anyone running sponsored ads, at no additional cost.
What Ads Data Manager Actually Does
Ads Data Manager lets you bring your own customer data, website activity, email lists, and purchase history from your own store into Amazon Ads and combine it with Amazon’s shopping, browsing, and streaming signals. The result is audience targeting built from real signals about your actual customers, not just Amazon’s inferred interest categories.
No additional data expertise is required. The tool is designed to work for smaller teams without dedicated data or analytics functions.
All data usage is privacy-safe and used exclusively for your own campaigns; your data does not feed Amazon’s broader systems or benefit competitors.

The Performance Gap It Closes
Amazon reports that advertisers using first-party data with Amazon Ads see a 30% higher ROAS compared to those who do not. That gap reflects the difference between targeting audiences based on behavioral inference and targeting them based on actual known customer relationships.
For brands that have built meaningful customer lists- email subscribers, repeat purchasers, site visitors- those lists now have a direct route into Sponsored Ads targeting. A customer who bought from your Shopify store but has not purchased on Amazon is a retargeting opportunity that previously required DSP to act on. It no longer does.
What to Do Now
The expansion is live globally. Access is in the Amazon Ads console under Ads Data Manager.
Three practical starting points: upload your customer email list and build a remarketing audience for Sponsored Display, create a lookalike segment based on your highest-LTV customers to use as a targeting signal in Sponsored Products, and compare ROAS on campaigns using first-party audiences against your standard campaigns over a 30-day window.
The tool is available. The data most brands already have. The gap between having customer data and using it inside Amazon Ads just closed.
