Amazon's order confirmations have stopped naming what you bought. Since roughly July, the emails have described a category instead of a product — one Hardware item, one Nutrition & Wellness, one Wireless Accessories — illustrated with generic clip art and no thumbnail. Orders placed as recently as June still showed the actual thing purchased.

Shoppers have two complaints. The first is practical: working out what you ordered now means leaving the email and opening Amazon. The second is that a message announcing a Beauty item has arrived, with no product name and no picture, looks a great deal like phishing.

Amazon has been rearranging these emails for years, and there are complaints stretching back about as far. This change is different in that there is a reasonably clear motive behind it, and the motive is AI.

The industry pitch for the past year has been the shopping agent — software that browses, compares and buys on your behalf. Google is better placed than anyone to deliver it, with billions of products in Shopping and a growing set of AI features wrapped around them. Gemini Spark already reads a user's mailbox for useful fragments, assembling a trip itinerary out of a concert ticket confirmation and details about their family. In May the company showed a cart that works across different merchants, destined for Gmail, so items can be added while you are reading mail or watching YouTube.

Every one of those capabilities runs on how much personal information the user is willing to hand over — and a mailbox full of itemised receipts is an unusually rich supply.

That puts retailers in an awkward spot, which The Verge has taken to calling the DoorDash problem. If agents work as well as their makers claim, a customer has no particular reason to visit the retailer's own site again. Walmart, Target and Wayfair have taken the bet anyway and plugged into Google's AI shopping surfaces, hoping people will research and buy through a chatbot. Amazon has not.

Amazon guards the direct relationship more jealously than most. It sued Perplexity last year over letting users shop on Amazon through its assistant, and lost — a judge found for Perplexity earlier this month. Meanwhile it is building the same capabilities in-house: price tracking, automatic reordering, and Alexa for Shopping inside the app, so a customer wanting recommendations or comparisons never has to open Gemini or ChatGPT to get them.

Asked directly whether the email change was meant to keep purchase data away from companies like Google, Amazon did not put it in those terms, but did not really deny it either. Spokesperson Maxine Tagay said customers increasingly check the Your Orders page in the app for consolidated, real-time status, so the company has simplified several order-related emails to point people there. The second half of the statement is the part that matters: the change, she said, cuts down on customer information travelling outside Amazon's own app and site, which the company presents as a privacy improvement.

Read plainly, it is both things at once. Less detail in your inbox does mean less for a third-party agent to harvest on your behalf, and less for one to harvest without your knowing. It also means the useful version of your own purchase history now exists only where Amazon can see you looking at it — and that you have to go there to look.
