Amazon now sells by text. The ad sits inside the conversation

You're in the grocery store and remember the coffee pods are almost gone. Old way: a note on your phone, open the app later, search, compare. New way, at least for some Americans: text "Alexa Shopping." Done.

Sounds like a convenience feature. It isn't. It's a new ad format.

What Amazon launched

Since November 6, invited US customers can link a phone number and get a contact called "Alexa Shopping." According to Digiday and GeekWire:

• Send a request as text or a photo, say a recipe or an outfit. The agent searches, compares and texts back options.
• It buys on request, or automatically once a price hits your target.
• It tracks prices, reorders, follows packages. The conversation carries across the app, the website and Alexa devices.
• Sponsored Products show up in the discovery stage. Purchases the agent completes on its own stay ad-free, per Digiday.
• Advertisers don't pay for these placements yet. Amazon is testing how much advertising users will tolerate.

"Millions more customers" are due in the coming weeks. Amazon says more than 400 million customers used Alexa for Shopping in the past 12 months and that use of agentic features grew more than eightfold since January. Company figures.

Five slots instead of fifty

Here's what I find interesting: a search results page has dozens of slots. A text message has a few. Digiday says each reply only has room for a handful of products. That means the consideration set isn't built by the shopper anymore. It's built by the agent. And part of it is paid for.

In my view, that's the real shift in retail media. Until now, you paid for visibility. Next, you pay to make the shortlist at all. If you're not in the first reply, you don't exist for that purchase.

The catch: the agent is salesperson and advisor at once

The second-order point: auto-purchases stay ad-free, suggestions don't. So the most valuable decision, which brand the agent picks on its own when the price is right, is organic. You can't buy it. You earn it through reviews, availability, price and clean product data.

And Amazon is building the wall around it. Meta's shopping agent Muse was already locked out this summer. Amazon wants customers talking to its agent, not someone else's.

What I'd do now

• Write product data for questions, not keywords. An agent answers "what goes with this recipe?" Does your listing say what the product is for, for whom, in what quantity?
• Treat reviews and stock as media. The agent auto-buys when price and trust line up. Out of stock means out.
• Budget a 2027 test for conversational ads. The winners will be the ones who learned early how to measure "a slot in the chat."

Bottom line: There's no page two in a chat. You're either in the answer or out of the game.
