Quick Summary

Klaviyo segmentation allows you to send targeted messages based on customer behavior, purchase history, and engagement. Most ecommerce brands underuse segmentation, leading to lower conversions and missed revenue opportunities.

  • Segmentation improves targeting and conversion rates
  • Built on behavior, engagement, and purchase data
  • Enables more personalized campaigns
  • Supports better deliverability and engagement
  • Most brands don’t fully leverage segmentation

How Does Klaviyo Segmentation Work?

Klaviyo segmentation is built on customer data.

Default Data Klaviyo Tracks

Klaviyo automatically collects:

  • Purchase history
  • Browse behavior
  • Email engagement (opens, clicks)
  • Site activity

This forms the foundation for segmentation.

What Are Custom Properties?

Custom properties are additional data points you collect about your customers.

Examples:

  • Product preferences
  • Quiz results
  • Gender, location, or interests

These allow for:

  • More personalized campaigns
  • More precise targeting
  • Better conversion rates

 

The more relevant your data, the more effective your segmentation.

 

How Does the Logic Builder Work?

Klaviyo uses AND / OR logic to define segments.

Examples:

  • Purchased in last 90 days AND opened last email
  • Viewed product OR added to cart

 

This allows you to create:

  • Highly specific segments
  • Dynamic targeting rules
  • Scalable personalization

 

Real-Time vs Static Segments

Real-time segments:

  • Update automatically
  • Add/remove users based on behavior

 

Static lists:

  • Fixed unless manually updated

 

Real-time segmentation is what makes Klaviyo powerful.

What Are the Essential Klaviyo Segments?

If you’re not using these, your targeting is too broad.

Active Customers

Definition: Purchased in the last 90 days

Why it matters:

  • Highest likelihood to buy again
  • Ideal for campaigns and cross-sells

 

At-Risk Customers

Definition: No purchase in 90–180 days

Why it matters:

  • Still recoverable
  • Key segment for win-back flows

 

Lapsed Customers

Definition: No purchase in 180+ days

Why it matters:

  • Low engagement
  • Should be targeted carefully or suppressed

 

VIP Customers

Definition: Top 10–20% by spend

Why it matters:

  • Highest lifetime value
  • Should receive exclusive offers

 

High Engagement / Low Purchase

Definition: Engaged but never bought

Why it matters:

  • Strong intent
  • Needs conversion-focused messaging

 

New Subscribers

Definition: Joined in the last 30 days

Why it matters:

  • Highest engagement window
  • Key for welcome flows

 

One-Time Buyers

Definition: Purchased once, never returned

Why it matters:

  • Biggest opportunity for LTV growth

 

Most brands send the same email to all of these groups, and that’s where revenue is lost.

How Do Klaviyo Predictive Analytics Segments Work?

Klaviyo includes predictive analytics that go beyond basic segmentation.

Predicted LTV

Estimates how much a customer will spend over time.

 

Churn Risk

Identifies customers likely to stop buying.

 

Expected Next Order Date

Predicts when a customer is likely to purchase again.

 

How to Use These

  • Trigger flows based on predicted behavior
  • Send campaigns at the right time
  • Prioritize high-value customers

 

Predictive segmentation lets you act before the customer disengages.

What Is RFM Segmentation and How Do You Use It?

RFM stands for:

  • Recency — how recently someone purchased
  • Frequency — how often they purchase
  • Monetary — how much they spend

 

How to Build RFM Segments in Klaviyo

Use combinations like:

  • High recency + high frequency = VIP
  • Low recency + high frequency = at-risk
  • Low frequency + low monetary = low value

 

How to Use RFM Segmentation

  • Personalize campaigns
  • Prioritize high-value customers
  • Adjust offers based on behavior

 

RFM is one of the simplest ways to improve segmentation immediately.

How Does Segmentation Impact Deliverability?

Segmentation directly affects deliverability.

When you:

  • Send to engaged users → higher opens and clicks
  • Avoid inactive users → fewer spam complaints

You improve:

  • Sender reputation
  • Inbox placement

Sending to everyone is one of the fastest ways to hurt deliverability.

→See the Klaviyo Deliverability Guide for deeper setup.

What Are Common Klaviyo Segmentation Mistakes?

Too Many Overlapping Segments

Creates confusion and inconsistent targeting.

 

Never Auditing Segments

Outdated segments reduce accuracy and performance.

 

Ignoring Engagement Data

Sending to unengaged users hurts both revenue and deliverability.

Good segmentation is simple, clear, and maintained regularly.

How Should You Use Segmentation With Flows?

Segmentation makes flows more powerful.

Examples:

  • Different welcome flows for VIP vs new users
  • Different cart flows for first-time vs repeat buyers
  • Different win-back flows based on churn risk

Flows + segmentation is where most performance gains happen.

Frequently Asked Questions

What is Klaviyo segmentation?

Klaviyo segmentation is grouping customers based on behavior, purchases, and engagement to send more relevant messages.

Start with 5–7 core segments, then expand as needed. Too many segments can reduce clarity and effectiveness.

It uses data to estimate customer behavior, such as lifetime value, churn risk, and next purchase timing.

Segment customers based on top 10–20% of spend or purchase frequency.

Custom properties are additional data points you collect, such as preferences or quiz results, used for deeper segmentation.

Sending targeted emails to engaged users improves inbox placement and reduces spam complaints.
