Automating Customer Conversations: Integrating Telnyx SMS and AI Agents with n8n
In a world where customer attention is short and expectations are high, instant communication isn’t a luxury—it’s a necessity. At Anpu Labs, we help modern businesses automate intelligently by combining best-in-class tools with custom AI workflows. One powerful example: integrating Telnyx SMS with AI agents and n8n to handle customer conversations on autopilot.
Here’s how we do it—and why this combination is a game-changer.
Why Automate SMS Conversations?
SMS is still one of the most effective ways to engage with customers. With open rates as high as 98% and average response times under 90 seconds, it's an ideal channel for:
Booking appointments
Answering frequently asked questions
Following up on lead forms
Delivering personalized promotions
Re-engaging dormant users
But managing this manually is time-consuming. That’s where automation comes in.
Tools of the Trade
n8n is a powerful, open-source workflow automation platform. We use it to build event-driven workflows that are flexible, visual, and developer-friendly.
Telnyx provides enterprise-grade programmable SMS at a fraction of the cost of legacy providers like Twilio. It’s reliable, scalable, and easy to integrate.
AI Agents (developed by Anpu Labs) are intelligent systems designed to respond to customer queries using retrieval-augmented generation (RAG), custom prompts, and integrations with business data.
How It Works
We built a system that connects all the dots. Here's a simplified breakdown:
Inbound Message Triggers Workflow
A customer sends an SMS to your Telnyx number. This incoming message triggers a webhook in n8n, kicking off the automation.Message Enrichment + Context Lookup
The AI agent accesses relevant business knowledge—product FAQs, recent orders, or user-specific data—via a RAG pipeline.AI Response Generation
The AI agent generates a human-like response tailored to the user’s query, combining static info (e.g., business hours) with dynamic content (e.g., order status).Response Sent via Telnyx SMS
n8n sends the AI-generated reply back to the customer through Telnyx in real-time.Analytics & Logging
All interactions are logged—tagged with intent, sentiment, and resolution status—for insight and continuous improvement.
Real Use Case: AI Scheduling Assistant
One of our clients needed to handle appointment scheduling via SMS. We implemented a conversational AI agent integrated with their booking system.
✅ The user texts “I want to schedule a consultation.”
✅ The agent checks availability and responds with time slots.
✅ The customer selects a time, and the agent confirms the booking.
✅ A reminder SMS is automatically sent 24 hours before the appointment.
This system ran 24/7, reduced back-and-forth communication, and helped the client capture more leads with less manual effort.
Why It Works
Always On: AI agents never sleep, ensuring 24/7 responsiveness.
Context-Aware: By combining AI with workflow automation, responses are timely and relevant.
Fully Customizable: Using n8n, we tailor every part of the workflow—from logic branches to fallback responses.
Cost-Efficient: Using Telnyx reduces messaging costs while maintaining deliverability and scale.
Future Potential
Integrating Telnyx SMS, AI agents, and n8n opens the door to even more use cases:
Automated onboarding sequences
Customer support ticketing via SMS
Loyalty program engagement
Real-time lead qualification
And with LLMs continuing to evolve, these agents are only getting smarter.
