Automate Everything by Omni · #8

Inventory-Driven Marketing Engine
with Shopify, Klaviyo & n8n

Your inventory is talking — your marketing isn't listening. This system connects Shopify stock levels to automated Klaviyo campaigns via n8n. Overstock clearance, low-stock urgency, trending product pushes — all driven by real inventory data, not guesswork.

The Problem

Your marketing team and your warehouse have never met.

📦

Overstock bleeding margin

Products sitting 60+ days. Storage costs climbing. You don't run a clearance campaign because you don't even know which SKUs are stuck. By the time you check, the margin is already gone.

Missed urgency windows

A bestseller drops to 20 units. Nobody on your team notices until it's sold out. You send a back-in-stock email 3 weeks later. The customer already bought from your competitor.

📈

Trending products discovered too late

A product suddenly sells 3x its normal rate. The marketing team finds out next month in a report. The momentum is already gone. You never capitalized on it.

💸

Blanket discounts killing profit

Every sale is "10% off sitewide." High-margin products get the same discount as low-margin ones. VIPs get the same code as first-time visitors. You're leaving money on the table every time.

The System

How inventory drives your marketing

Three engines running in the background. Every campaign is triggered by real inventory data, not a marketing calendar. Your stock levels decide what gets promoted, when, and to whom.

1
Overstock Liquidation Engine
Products sitting too long get flagged automatically. AI calculates the minimum discount needed to move them without destroying your margin. Campaign fires to the right segment — no blanket sales, no guessing.

Low Stock Urgency Engine
When a product drops below threshold, the system calculates how many days of inventory remain at current velocity. Customers who browsed or carted it get an urgency push — before it sells out, not after.

Trending Product Amplification
When a product's sell rate spikes 2x+ above its 30-day average, the system catches it in real time. If there's enough inventory to support a push, a "trending now" campaign fires automatically to lookalike buyers.

The Intelligence Layer

Every discount is calculated, not guessed

Across all three engines, the system pulls product cost, current margin, inventory age, and customer lifetime value before deciding what offer to make. No more blanket codes.

High Margin + Heavy Overstock + VIP

Aggressive clearance

Product has 65% margin and has been sitting 90+ days. Customer has $800+ CLV. System generates a 25-30% single-use code with 48hr expiry.

25-30% OFF
High Margin + Moderate Overstock + New Customer

Acquisition offer

Product has 55% margin, 50 days in stock. Customer is first-time browser. System generates a 15% welcome code to convert the first purchase.

15% OFF
Low Margin + Any Stock Level

Protect the margin

Product only has 25% margin. No room for discounting without losing money. System offers free shipping instead — moves product without cutting price.

FREE SHIPPING
Any Margin + VIP + Trending Product

Early access, no discount

Product is trending. VIP customer with high engagement. No discount needed — exclusivity is the offer. System sends early access notification before the campaign goes wide.

What this system actually does for your store

Founder, Omni Online Strategies
Klaviyo is the best email engine for Shopify. But it can't see your warehouse. It doesn't know which products are stuck, which ones are about to sell out, and which ones are suddenly trending. This system gives Klaviyo a brain it doesn't have. Most DTC brands are running Klaviyo's built-in flows and calling it done. Welcome series, abandoned cart, browse abandonment — that's table stakes. The brands that pull ahead are the ones whose marketing reacts to what's actually happening in the business, not just what customers click on. This system makes your inventory the trigger.
