Klaviyo: Segmentation & Personalization

A first-time buyer and your best customer shouldn’t get the same email.

One List, Many Customers

Everyone on your list gets the same message, so new buyers, regulars and lapsed customers all hear the same pitch. That leaves money on the table.

We build segments from real purchase behavior, product categories, customer value and engagement. Each email then speaks to customers in a way that matches their relationship with your brand. We keep it helpful and product-focused, so it never feels like spying.

How Messages Get Personal

Segments based on purchase behavior and customer value

Dynamic content blocks that change by segment

RFM segments, which rank customers by recency, frequency and spend

Predictions and suppression rules that protect your engagement

Building Segments That Matter

1

Read the Data

We look at purchases, product categories, customer value and engagement to see which groups really behave differently.

2

Define Core Segments

New customers, repeat buyers, VIPs, lapsed customers and category groups come first, because they change how you communicate.

3

Score With RFM

RFM scoring shows your best customers, those at risk of leaving and those who need a nudge, then feeds flows and campaigns.

4

Personalize Content

Dynamic blocks and product data let each email reflect what someone viewed, bought or left in their cart.

Why Choose System Strats

We work across Shopify, BigCommerce, WooCommerce and ERPs, so we understand Klaviyo in the context of the broader ecommerce operation. That helps us build segments on the customer data your other systems hold, rather than treating email as a silo.

Frequently Asked Questions

Fewer than you’d think. A handful of meaningful segments beats dozens of overlapping ones. We focus on those that change how you communicate: new customers, repeat buyers, VIPs, lapsed customers and category-specific groups.

RFM stands for recency, frequency and monetary value. It’s a simple way to spot your best customers, those at risk of leaving and those who need a nudge. Our RFM segments feed targeted flows and campaigns.

By staying helpful. We focus on product-level relevance and value, avoid overly specific personal details, and respect customer preferences at every step.
