Bulk SMS vs AI Conversations: A 3x Conversion Rate Case Study

We recently worked with Good To Go Garages to test the difference between traditional bulk SMS and our AI conversational approach. The results? A 3x increase in conversion rates. Here's exactly how we did it.

The Challenge: 1500+ Past Clients, Zero Scalability

Good To Go Garages wanted to re-engage over 1500 past clients to book garage door annual service appointments—essential for maintaining warranties and fixing minor issues. Cold calling every single client wasn't practical. Their sales team was already handling new clients daily, and adding 20+ cold calls per day on top of that would crush their bandwidth.

Traditional bulk SMS was the obvious alternative, but it came with a major problem: friction. By asking clients to call back, conversion rates stayed disappointingly low.

The Test: Bulk SMS vs AI Conversation

We ran a head-to-head test with virtually identical copy, but with one key difference:

• Bulk SMS: Asked clients to call the business directly to schedule their service
• AI SMS: Started a conversational thread by asking if their garage door had been serviced lately

The AI approach included automatic follow-ups (which alone drives an extra 30% conversion rate) and only forwarded positive responses to the sales team. If a client said they weren't interested or hadn't had their door serviced, the AI explained why they should—and then asked if they'd like to schedule a call.

The Results: 3x Better Conversion Rate

The AI conversational SMS delivered a conversion rate three times higher than bulk SMS. By removing the friction of "call us back" and only surfacing warm leads to the sales team, Good To Go Garages got most of the benefits of cold calling without the time investment.

As Nabil from Good To Go Garages confirmed, this is exactly what we outlined at the start—and it's exactly what we delivered.

The Bridge Between Bulk SMS and Cold Calling

This approach isn't a replacement for your sales team actually calling clients. It's a force multiplier that sits between bulk SMS and cold calling, giving you:

• The scale of bulk messaging
• The engagement of a real conversation
• A pre-qualified pipeline of warm leads for your sales team

If you're currently running bulk SMS campaigns as a service-based business, we highly recommend experimenting with conversational AI. The results speak for themselves.
