Welcome to KlavX — the fastest way to connect your Lightspeed Retail X POS with Klaviyo for smarter email marketing and better customer data.
This guide walks you through everything you need to get set up in under 10 minutes.
1. What is KlavX?
KlavX is a simple integration tool that syncs your in-store customer and sales data from Lightspeed Retail X directly into Klaviyo.
This means:
You can send email campaigns to your in-store customers
Automate flows based on purchases made in-store
Build segments combining online and offline behaviours
Track real ROI from your POS data
No more manual exports or complicated API builds — just plug in and go.
2. How KlavX Works
KlavX works in the background to keep your systems in sync.
✅ Customer data: names, emails, phone numbers, and consent preferences
✅ Sales data: products, categories, brands, order values
✅ Sync frequency: every 15 minutes (default), or real-time (available soon)
✅ Duplicate protection: KlavX checks if a customer or sale already exists before syncing
