If you're running a retail business on Lightspeed POS, you already know it's great for managing inventory, processing sales, and keeping your shop floor running smoothly.
But here's the thing: Lightspeed wasn't built for marketing.
Every transaction, every customer profile, every purchase pattern sitting in your POS is data that could be driving repeat sales, building loyalty, and growing your revenue on autopilot. The problem is getting that data out and into a tool that knows what to do with it.
That's where Klaviyo comes in.
What Klaviyo Does That Lightspeed Can't
Klaviyo is purpose-built for ecommerce and retail email marketing. While Lightspeed tracks what happened, Klaviyo helps you do something about it.
With your Lightspeed data flowing into Klaviyo, you can:
- Segment customers by purchase behaviour - not just demographics, but what they bought, when, and how often
- Trigger automated flows - welcome series, post-purchase follow-ups, win-back campaigns for lapsed customers
- Personalise at scale - product recommendations based on actual purchase history, not guesswork
- Track revenue attribution - know exactly which emails drove which sales
The Gap Between Lightspeed and Klaviyo
Lightspeed and Klaviyo don't have a native, real-time integration. That means most retailers are either:
- Doing nothing - leaving money on the table because the data never reaches their email platform
- Exporting CSVs manually - tedious, error-prone, and always out of date
- Using Zapier - which works for basic triggers but can't sync full purchase history or handle complex segmentation data
None of these are good enough if you're serious about retention.
What a Proper Integration Looks Like
A real Lightspeed-to-Klaviyo integration should:
- Sync customer profiles automatically as they're created or updated in Lightspeed
- Push transaction data in real-time so Klaviyo segments and flows always have fresh data
- Include product details so you can build recommendations and cross-sell flows
- Handle historical data so you're not starting from zero
This is exactly what Gather does. We sit between Lightspeed and Klaviyo, keeping both systems in sync without any manual work.
The Revenue Impact
Retailers using Klaviyo with connected POS data typically see:
- 3-5x higher email revenue compared to batch-and-blast campaigns
- 20-30% of total revenue from automated email flows within 6 months
- Significant improvement in repeat purchase rate through targeted win-back and loyalty campaigns
The data is already in your POS. The customers are already in your store. The only missing piece is the connection.
