How to Use AI Database Reactivation to Rebook Past Customers via SMS

You have thousands of past customers sitting in your CRM right now, people who already trust your business, who have already paid you, and who would likely buy again if someone simply reached out. The problem is that no one on your team has the time to call them. That is exactly the gap that AI database reactivation fills.

In this episode, David Jenyns sits down with Gareth Rydon, co-founder of Friyay.ai, to unpack how small businesses are using AI-powered SMS assistants to restart conversations with dormant contacts, book them into services, and respond to new enquiries in seconds instead of days. If you have been looking for a practical, revenue-first place to start with AI, hit play.

📋 AI Database Reactivation: A 6-Step SMS Sales Playbook

Based on the interview with Gareth Rydon, Co-Founder of Friyay.ai

Gareth’s approach to AI-powered SMS outreach follows a practical, step-by-step sequence that any small business can adopt. Below is the framework he walked through during the conversation, expanded with context from real client examples he shared.

Step 1: Start Where the Money Is

Before touching any AI tool, get clear on where revenue is being left on the table. Gareth recommends asking one question: if you had 10,000 salespeople ready to call every customer and get them to take one action, what would that action be? The answer becomes your campaign brief. Most business owners already know the conversation they are dying to have with their customers. They just lack the capacity to have it at scale.

Starting with the highest-value conversation, rather than trying to automate everything at once, gives you a focused campaign that delivers fast results.

Step 2: Build Your Reactivation List

Pull together a list of past customers or prospects who have already interacted with your business and who have opted in to receive communications. These are people who already trust you and are far more likely to respond than cold contacts.

In one of Gareth’s client examples, a pest control business was sitting on a database of 14,000 past customers. The owner knew that many of those customers were overdue for a spray, but the small office team simply could not get through the list by phone. That dormant database became the foundation of a highly effective AI reactivation campaign.

Step 3: Craft a First Message That Is Easy to Say Yes To

The opening SMS needs to feel like a genuine conversation, not a marketing blast. Gareth stresses that despite being under 160 characters, significant design thinking goes into that first message. It should contextualise the relationship (“you got a spray from us in the past”), surface a relevant concern (“are you worried about termites in your area?”), and make it effortless for the recipient to reply with a simple yes.

In Friyay’s testing, the choice of even a single word can shift response rates by five to ten percent. The goal is to break the pattern of mass-marketing SMS so the customer realises this is an actual two-way conversation.

Step 4: Set Up Your AI Assistant Behind the SMS Channel

The technical setup involves getting a compliant mobile number and connecting an AI assistant (built on tools like ChatGPT or Claude) to sit behind that SMS channel. In Australia, the Spam Act requires your first message to include opt-out options such as the words “no,” “stop,” or “delete.” Gareth notes that Friyay invested significant time ensuring the compliance language still feels human rather than robotic.

If you are operating in New Zealand, the requirements are even more stringent and costly, so factor in local regulations early. SMS remains the fastest path to revenue for most Australian businesses because it has better cut-through than email or phone calls, and the compliance setup is more straightforward than WhatsApp.

Step 5: Keep Each Campaign Focused on One Job

Resist the temptation to make your AI assistant do everything in a single SMS thread. Each campaign should have one clear objective: book a pest spray, schedule a skin check, follow up on a proposal.

Gareth uses the example of medical centres reaching out to patients after summer to book skin checks. The assistant’s brief is simple: help the patient understand whether they need a skin check, and if so, book them in. That is it. Over SMS, customers want the interaction wrapped up in 90 seconds or less. A tightly scoped campaign also makes the messaging flow much easier to design and test.

Once one campaign is working, you can layer in the next one with confidence because you are building from lived experience rather than theory.

Step 6: Add Speed-to-Lead for Inbound Enquiries

Once your outbound reactivation campaign is running, the natural next step is inbound response automation. Many businesses receive website enquiries at times when no one is available to reply, particularly on Friday and Saturday evenings for wellness and cosmetic clinics. By the time a team member responds on Tuesday morning, the prospect has moved on. Gareth shared data suggesting that responding within the first 30 minutes of an enquiry makes you roughly 12 times more likely to convert that lead.

An AI assistant that replies immediately, answers clarifying questions, and books a consultation on the spot captures revenue that would otherwise be lost to slow follow-up. Even a simple acknowledgement and calendar booking is vastly better than a voicemail promise that someone will call back.

What makes Gareth’s approach so practical is the constraint he puts around getting started: one campaign, one conversation, one clear action. Too many business owners stall on AI because they see hundreds of possible applications and cannot decide where to begin. The answer, as this episode makes clear, is to start where the money is. Pick the one conversation you wish you could have with every past customer, let an AI assistant have it for you over SMS, and watch the bookings come in.

Once you have seen it work with your own data and your own customers, you will never wonder where to apply AI next.
