Introducing AI-Powered SMS Integration With Siena x Klaviyo

From day one, we built Siena with a bold vision: one AI agent should seamlessly power every customer interaction, regardless of channel. While others patch together different solutions for chat, email, and SMS, we've taken a fundamentally different approach.

Why SMS Support Needs a Rethink

Modern e-commerce brands are increasingly turning to SMS marketing for its immediacy and engagement rates. Klaviyo leads this transformation, helping brands deliver personalized SMS campaigns that drive real results. But here's the challenge: when customers reply, brands are forced to choose between slow manual responses or clunky help desk workflows that break the conversational nature of SMS.

Enter Siena: First AI Agent for Klaviyo SMS

We're proud to lead the way in bringing truly conversational support to Klaviyo SMS campaigns. This isn't just another integration – it's the first solution that maintains the natural flow of SMS while delivering intelligent, automated responses.

From Campaign to Conversation

When your customer hits "reply" to a Klaviyo SMS campaign, something different happens with Siena. Instead of their message disappearing into a help desk queue or requiring manual routing, here's the exact flow:

Your customer's reply flows directly into Siena through our native Klaviyo integration. No middleware, no complex routing - just instant connection. Siena immediately:

• Understands the context of their original SMS campaign

• Accesses their customer history and preferences

• Responds through the same SMS thread they're already using

Why This Matters

Imagine sending a promotional campaign to 10,000 customers. With traditional setups, even a 1% response rate means 100 conversations your team needs to manually handle. With Siena, these responses are automatically managed while maintaining:

• Brand consistency through dedicated SMS personas

• The natural flow of text conversation

• Seamless handoff to your support team for complex issues

Because Siena was built for cross-channel support from day one, it doesn't just handle SMS in isolation. The same AI brain that manages your SMS responses also powers your chat, email, and other support channels - creating truly unified customer intelligence.

How It Works in Practice

Let's look at a real scenario:

• Your brand sends a Valentine's Day campaign with a 10% discount code

• A customer replies a week later: "Hey, I bought something but can't track my order"

• Siena instantly checks your order management system

• The customer receives their tracking info directly via SMS, in seconds

Or another common situation:

• A promotional code isn't working for a customer

• Instead of waiting for support, Siena can automatically provision a new code

• The customer completes their purchase without leaving SMS

This integration is just the beginning. We're working on some exciting initiatives to further our partnership, like bi-directional insights sharing between Siena and Klaviyo, enhanced personalization based on cross-channel interaction history, and deeper integration with your e-commerce stack.

The Power of True Multi-Channel Support

Siena was built from the ground up to be channel-agnostic. Whether your customer reaches out via chat, email, or SMS, they're interacting with the same intelligent agent that knows their history and can provide consistent, personalized support.
