Sell through two-way AI SMS conversations

The problem

SMS gets read, but replies such as "does this come in blue?" or "when will it be back in stock?" often go unanswered or wait hours for a human, so high-intent shoppers drift away.

How AI helps

Conversational SMS tools use AI trained on your catalogue, policies and past conversations to answer replies in seconds, recommend products, share a checkout link and hand off to a person for anything sensitive. They work best on top of well-segmented campaigns and flows.

How to roll it out

1. 1

   Confirm consent and UK PECR rules: marketing texts need prior opt-in and an easy STOP option.

2. 2

   Start with cart recovery, back-in-stock and post-purchase flows where replies are most likely.

3. 3

   Give the AI clear guardrails: discount limits, topics it must hand over (allergies, complaints, refunds).

4. 4

   Review every AI conversation daily for the first two weeks, then sample weekly.

5. 5

   Measure revenue per message and opt-out rate together.
