Postscript Shopper: AI Agents, Channels and the Rollout

By Rene Siller, Zobi. Sources checked 2026-11-13.

What Postscript's Shopper agents do, which channels they cover today, the order brands switch them on, and what to check before an AI-run SMS program goes live.

## Quick answer

Postscript Shopper is a set of AI agents inside Postscript that decide and write one-to-one messages for each subscriber. Postscript names four on its Shopper page (https://postscript.io/shopper). Responses handles conversations when a subscriber texts in. Automations decides each subscriber's next message and replaces welcome, abandonment and lifecycle flows. Campaigns decides who should get a campaign and what it should say. Ask Shopper lets you search and query what customers are telling you. All of them draw on the voice, offers, FAQs and catalogue you set in Brand Center.

Shopper works across SMS and RCS today, and Postscript says more channels are coming. Every brand starts with Brand Centre and Shopper Responses, then can expand into Shopper Automations and Campaigns (Alpha), in Postscript's wording. The Shopper page does not publish a price and routes you to a demo instead.

## Shopper starts with Brand Center and Responses

Shopper is easier to evaluate as five pieces than as one product, because the pieces arrive at different points. The table follows the order Postscript gives for getting started.

Table: Shopper components, in Postscript's rollout order
Component | What it does, per Postscript | When a brand gets it
Brand Center | Holds the voice, offers, FAQs, catalogue and strategies every Shopper message pulls from | At the start
Responses | Answers subscribers who text in, works through objections, recommends products and closes the sale | At the start
Automations | Decides each subscriber's next message and replaces welcome, abandonment and lifecycle flows | Expansion
Campaigns | Decides who should get a campaign and what it should say | Expansion, listed as Campaigns (Alpha)
Ask Shopper | Makes conversations searchable so you can query them and get reports | Not given in the rollout description

Source: Postscript's Shopper page (https://postscript.io/shopper), FAQ answers on Shopper agents and on getting started. Brand Center is the set of inputs Shopper reads from, not one of the four agents.

The order matters if abandoned carts are your reason for looking at Shopper. The agent that replaces abandonment flows is Automations, and Postscript's path puts it after Brand Center and Responses. So a brand's first live Shopper stage is an agent that replies when subscribers text in. That is useful on its own, but it is not the same as Shopper taking over cart follow-up. In the demo, ask when Automations would be switched on for your account and what keeps running your current abandonment messages until then.

Postscript describes the agents as reading from one shared context platform, so work passes between them in a logical sequence. Each subscriber's profile combines browse and cart data with what that person says in conversations. For every message, the agents decide when to send, what to say, which offer to include and how to personalise it. Postscript says Shopper uses the same mechanisms as its Infinity Testing product, and that the longer it runs, the more it learns which strategies work for different groups of subscribers.

## Brand voice, preview and support handoff

Shopper is trained on your Brand Center inputs, your Shopify store and your knowledge base. You set the voice, tone and banned language, and Postscript says you can preview real conversations in Shopper Playground and make adjustments before anything goes live. For a supplement brand, that preview is where you see how Shopper handles everyday shopping questions before any subscriber gets an answer.

Two ordinary checks tell you a lot. Ask about a product that is already in a cart, such as whether the 60-count comes in a larger size, and see whether the answer matches your catalogue. Then ask whether that product has a subscription option, and compare the reply with how you actually sell it. If an answer is off, trace whether it came from your catalogue, your FAQs or your offers, since those are the inputs Postscript says Shopper draws on.

Then look at the handoff. Postscript says Shopper can point subscribers to your support email, phone number or contact form, or open a ticket directly in Gorgias or Zendesk that carries the last 10 messages, so your team is not starting cold. Postscript gives cancellations and refunds as examples of topics that need that extra help. Ask to see one of those requests reach your helpdesk, and check what your support team actually receives.

Postscript also says that for regulated categories such as health and supplements, Shopper runs with built-in guardrails on medical claims and that individual use cases are reviewed before going live. Ask what that review covers for your products and who on your side signs off. It describes Postscript's process; your own review of product claims still applies.

## Which channels Shopper covers today

Shopper's FAQ says it works across SMS and RCS today. Postscript calls these the most conversational marketing channels and says Shopper is expanding across the customer journey, with future channels to follow. The page does not name those channels or give dates.

Postscript also sells an Email product, listed separately in its navigation, but the Shopper FAQ does not include email among Shopper's channels today. If a large part of your customer base answers somewhere other than SMS or RCS, ask what future channels means for your account and when.

Shopper is part of Postscript's platform and works on your subscribers under Postscript's platform rules for opt-outs, quiet hours and consent. For a brand on another SMS provider, then, evaluating Shopper also means evaluating Postscript. Our Postscript alternatives (https://zobi.com/dtc/compare/postscript-alternatives/) and Postscript vs Attentive (https://zobi.com/dtc/compare/postscript-vs-attentive/) comparisons cover that wider decision.

## What to ask Postscript before you buy

Ask Postscript to demonstrate Shopper against the work your store needs it to do. Bring a real product question, an abandoned cart and a request that should reach your support team. Then settle the commercial and rollout questions:

What Shopper costs for your list size, since the Shopper page publishes no price.

When Automations would go live for your account, and what runs your abandonment messages until then.

What the Alpha label on Campaigns means for availability and support.

Which future channels are planned, and whether any have dates.

Which topics escalate to your support team by default, and whether you can change that list.

Who on your team keeps Brand Center current as products, offers and FAQs change.

## Choose Zobi for conversations across more channels

If Shopper appeals to you because each customer gets a personal message instead of the same blast as everyone else, Zobi is built around that kind of conversation too, with wider channel reach and a sign-off step on every campaign.

Zobi texts shoppers like someone from your team. It starts on iMessage where possible and uses RCS, SMS, WhatsApp or email when needed. Cart recovery, replies, reorders and add-ons run in one thread that remembers the cart, the last reply and what the customer bought, so a question about a larger size is answered in the same conversation that brought the shopper back to the cart. Zobi's concierge reads the cart and writes and personalises each message. You approve every campaign before a word goes out, and you can read the full transcript afterwards.

Shopper is a strong fit for a brand committed to a Postscript SMS program, with Brand Center controls, Playground previews and helpdesk handoff in place. If you want the shopper conversation to reach customers on iMessage, WhatsApp and email as well, with your approval on each campaign, apply with your Shopify store.
