When Twilio and Klaviyo operate independently, critical customer engagement data can be lost. For instance, if a customer responds to a Twilio SMS, that interaction is not automatically recorded in Klaviyo. As a result, marketing teams manually enter this response data into Klaviyo, wasting hours each week and increasing the risk of human error. This disconnect means that follow-up campaigns may not be tailored to customer behavior, ultimately affecting conversion rates.

Top Ways to Automate Twilio & Klaviyo

Automated SMS Notifications: Instantly send personalized SMS notifications to customers based on their behavior in Klaviyo, ensuring timely communication that enhances engagement and drives conversions.
Triggered Email Campaigns: Automatically trigger targeted email campaigns in Klaviyo when specific events occur in Twilio, such as a missed call or a new SMS inquiry, ensuring no lead goes unattended.
Centralized Customer Insights: Synchronize customer data between Twilio and Klaviyo to create a unified view of customer interactions, allowing for more informed decision-making and tailored marketing strategies.

How to Build the Twilio → Klaviyo Sync

Set up a Twilio webhook to listen for incoming SMS messages. Use the endpoint: https://api.twilio.com/2010-04-01/Accounts/{AccountSid}/Messages.json.
In your Twilio console, configure the webhook URL to point to your server endpoint that processes incoming messages.
Extract the relevant payload data from the incoming webhook, specifically the From, Body, and Timestamp fields.
Prepare a JSON object with the extracted data formatted for Klaviyo. For example: { "phone_number": "From", "message": "Body", "received_at": "Timestamp" }.
Use the Klaviyo REST API to insert this data. POST to the endpoint: https://a.klaviyo.com/api/v1/identify with your API key in the headers and the prepared JSON object in the body.

Developer Warnings & API Gotchas

Ensure that the phone number format from Twilio matches the expected format in Klaviyo. Twilio may return numbers with country codes, while Klaviyo might expect them without.
Be cautious of the data types; Klaviyo may require the received_at timestamp in a specific ISO 8601 format, which may differ from Twilio's output.
When mapping the Body of the SMS, ensure that special characters are properly encoded to prevent JSON parsing errors when sending to Klaviyo.
