# Introduction

## Overview
Our integration with [Klaviyo](https://klaviyo.com) enables brands to create customer segments and trigger automated flows using verified retail purchases and account connection events from Subtotal.
This integration makes it easy to:
* Segment customers based on real-world retail purchases
* Trigger flows when customers link or unlink accounts
* Engage with retail customers in real-time
Connect your Klaviyo account to get started.
