How to Create a Segment in Klaviyo

Creating targeted and dynamic email campaigns stands as one of the most powerful strategies to boost your email marketing performance. Klaviyo segments help you automatically group your contacts based on behavior, profile properties, or custom criteria that update in real-time as your customers take action. This comprehensive guide will walk you through everything you need to know about creating effective segments in Klaviyo—from fundamental concepts to advanced techniques that will transform your marketing strategy.

What Are Klaviyo Segments?

Klaviyo segments function as dynamic groupings of contacts defined by specific rules and conditions you establish. Unlike static lists where you manually add or import contacts, segments update automatically as people meet or no longer meet your defined criteria. This automatic updating ensures your marketing always reaches the right audience at the right moment without constant manual intervention.

The power of segments lies in their ability to reflect real-time customer behavior. For example, you might create a segment for customers who purchased a specific product in the last 30 days or for subscribers who haven’t opened any emails in the past two months. These dynamic groupings help you send highly targeted campaigns, trigger automated flows, and perform detailed audience analysis with minimal effort.

Segments serve as the foundation for personalized communication strategies. By grouping contacts based on similar characteristics or behaviors, you can craft messages that speak directly to their specific needs and interests. This targeted approach typically results in higher engagement rates, improved conversion rates, and ultimately, increased revenue for your business.

Benefits of Strategic Segmentation

Effective segmentation transforms generic marketing into personalized conversations with your audience. The strategic grouping of contacts based on specific criteria allows you to tailor your messaging to address unique customer needs and behaviors.

Segmentation delivers measurable improvements to your marketing performance. Campaigns sent to highly targeted segments often generate three times more revenue per recipient compared to unsegmented campaigns. This dramatic increase occurs because relevant messages naturally drive higher open rates, click-through rates, and conversion rates across your marketing efforts.

Dynamic updates represent another key advantage of Klaviyo segments. As customer behaviors change, your segments automatically adjust in real-time, ensuring your marketing always reaches the right people. This automatic updating saves countless hours of manual list management while maintaining the accuracy of your targeting.

When to Use Segments vs. Lists

Understanding when to use segments versus static lists can significantly impact your marketing effectiveness. Segments work best for dynamic groupings that change based on customer behavior, while lists serve better for fixed groups that rarely change.

Segments excel when you need to target based on changing behaviors. For example, creating a segment of customers who haven’t purchased in 60 days allows you to automatically send re-engagement campaigns to the right people at the right time. The segment updates itself as customers make purchases, removing them from the re-engagement flow without any manual intervention.

Lists prove more appropriate for permanent groupings or imported contacts. If you collect emails at a trade show or want to maintain a VIP group that you manually curate, a static list offers the right solution. Lists don’t automatically update based on behavior, giving you complete control over membership.

Creating Your First Klaviyo Segment

Starting with your first segment requires navigating to the right section of your Klaviyo account. The process begins with accessing your dashboard and finding the segment creation tools.

The segment builder interface provides an intuitive way to define exactly who should be included in your target audience. With a clear understanding of the basic navigation, you can quickly move on to creating powerful segments that drive your marketing strategy forward.

Setting up your first segment establishes the foundation for more sophisticated targeting in the future. As you become comfortable with the basic process, you’ll find it easier to implement advanced segmentation strategies that deliver even better results for your campaigns.

Navigating to the Segment Builder

Finding the segment builder requires just a few simple clicks within your Klaviyo account. After logging in to your dashboard, locate the “Audience” option in the left-hand navigation menu and click to expand it.

Select “Lists & Segments” from the dropdown menu to access your existing segments and create new ones. This section displays all your current lists and segments in one convenient location for easy management.

Look for the “Create New” button in the upper right corner of the screen and click it to begin the segment creation process. When prompted with options, select “Create Segment” to open the segment builder interface where you’ll define your targeting rules.

Defining Your First Segment Conditions

Starting with a clear, descriptive name helps you identify your segment’s purpose later. Choose a name that clearly indicates who’s included and why, such as “Customers Who Purchased in Last 30 Days” rather than simply “Recent Customers.”

The heart of any segment lies in its conditions—the rules that determine who belongs. Click the “Select a condition” dropdown menu to view available options, which typically fall into categories like “What Someone Has Done” (behavioral conditions) or “Properties About Someone” (profile details).

For your first segment, consider starting with a simple condition like “Placed Order at least once” or “Opened Email at least once in the last 30 days.” This straightforward approach helps you understand how conditions work before building more complex segments.

Combining Multiple Conditions Effectively

Powerful segments often use multiple conditions to precisely target specific audience groups. Adding a second condition allows you to narrow or expand your segment based on additional criteria that matter to your marketing goals.

The connection between conditions dramatically affects who qualifies for your segment:

• Using “AND” between conditions requires contacts to meet both criteria (narrowing your audience)
• Using “OR” between conditions includes contacts who meet either criterion (expanding your audience)

For example, creating a segment with “Placed Order at least once in the last 30 days” AND “Opened Email at least once in the last 7 days” targets recent customers who remain engaged with your emails—a perfect audience for cross-selling campaigns.

How to Use Advanced Segment Features

Advanced segmentation features unlock powerful targeting capabilities beyond basic conditions. These tools help you create highly specific segments that drive exceptional marketing results through precise audience targeting.

Klaviyo’s advanced features save time while improving accuracy in your segmentation strategy. Understanding these tools allows you to build sophisticated segments without spending hours manually configuring complex conditions.

Mastering advanced features transforms your segmentation from basic to strategic. With these tools at your disposal, you can create segments that precisely match your marketing objectives and deliver outstanding results.

Leveraging the Define with AI Tool

Klaviyo’s Define with AI tool revolutionizes segment creation by generating conditions based on simple descriptions. This feature helps you quickly build segments even when you’re unsure how to structure the necessary conditions.

To use this powerful tool, click “Create New” and select “Create Segment” as usual. Instead of manually setting conditions, look for the “Define with AI” option and enter a simple description of your desired audience, such as “customers who purchased summer products but haven’t bought anything in three months.”

The AI analyzes your description and generates appropriate segment conditions automatically. You can accept the suggested conditions or click “Open in builder” to refine them further, giving you a perfect starting point for complex segments without the technical setup.

Creating and Using Segment Snapshots

Segment snapshots provide a static record of who belonged to a dynamic segment at a specific moment. This feature proves invaluable when you need to preserve a particular audience grouping for historical analysis or one-time campaigns.

Creating a snapshot takes just a few clicks:

• Navigate to your existing segment
• Click the “Manage Segment” dropdown menu
• Select “Snapshot segment”
• Name your snapshot for easy reference

Unlike dynamic segments that continuously update, snapshots remain fixed. This static nature makes snapshots perfect for maintaining consistent audiences for A/B testing, preserving groups for compliance documentation, or analyzing how segment membership changes over time.

Cloning Conditions for Faster Building

The condition cloning feature dramatically speeds up segment creation when working with similar or related criteria. This time-saving tool allows you to duplicate existing conditions rather than rebuilding them from scratch.

To clone a condition, locate the clone icon (typically appearing as two overlapping squares) next to any existing condition in your segment builder. Clicking this icon creates an exact duplicate of the condition, which you can then modify as needed.

Cloning proves especially valuable when building complex segments with multiple similar conditions. For example, if you’re creating a segment based on purchase behavior across several product categories, you can set up one product condition perfectly, then clone and modify it for each additional category—saving significant time and reducing errors.

Powerful Segmentation Strategies

Strategic segmentation transforms generic marketing into personalized conversations with your audience. By implementing thoughtful segmentation strategies, you can dramatically improve campaign performance while building stronger customer relationships.

Effective segmentation strategies align with specific business objectives. Whether you’re looking to increase repeat purchases, reactivate dormant customers, or identify your most valuable audience segments, the right segmentation approach can help you achieve your goals.

The most powerful strategies combine multiple data points to create highly targeted audience groups. By considering both behavioral data (what customers do) and profile data (who customers are), you can create segments that deliver exceptional marketing results.

Customer Lifecycle Segmentation

Customer lifecycle segmentation groups contacts based on their relationship stage with your brand. This approach allows you to deliver perfectly timed messages that match each customer’s current needs and interests.

Common lifecycle segments include:

• New subscribers: People who joined your list within the last 7-14 days
• First-time customers: Those who made their first purchase but haven’t returned
• Active repeat customers: People who have purchased multiple times within a recent period
• At-risk customers: Previously active customers showing declining engagement
• Lapsed customers: Those who haven’t purchased in an extended period

Creating segments for each lifecycle stage enables you to develop targeted campaigns that move customers forward in their journey. For example, you might send product education content to new customers while offering loyalty rewards to active repeat purchasers.

Engagement-Based Segmentation

Engagement segmentation groups contacts based on how actively they interact with your emails and website. This strategy helps you identify your most engaged subscribers while spotting those who may need re-engagement efforts.

To create engagement-based segments, consider metrics like:

• Email open frequency (opened emails at least X times in Y days)
• Click activity (clicked links at least X times in Y days)
• Website visits (visited site at least X times in Y days)
• Purchase recency (purchased within the last X days)

Highly engaged segments typically respond well to exclusive offers and early access opportunities. Meanwhile, low-engagement segments benefit from re-engagement campaigns with attention-grabbing subject lines and special incentives to return.

Purchase Behavior Segmentation

Purchase behavior segmentation groups customers based on their buying patterns and preferences. This approach allows you to create highly relevant offers that align with each customer’s demonstrated interests.

Effective purchase behavior segments might include:

• High-value customers: Those who spend above a certain threshold
• Category enthusiasts: Customers who repeatedly purchase from specific product categories
• Discount buyers: Those who primarily purchase during sales
• Seasonal shoppers: People who buy during specific times of year

By understanding these purchase patterns, you can tailor your marketing accordingly. For example, you might avoid discounting to full-price shoppers while offering special promotions to price-sensitive segments that won’t purchase without incentives.

Best Practices for Effective Segmentation

Following proven best practices ensures your segments deliver maximum marketing impact. These guidelines help you avoid common pitfalls while implementing segmentation strategies that drive meaningful results.

Effective segmentation requires ongoing refinement based on performance data. Regularly reviewing your segments and adjusting your approach based on results helps you continuously improve your targeting precision.

The most successful segmentation strategies balance specificity with practicality. While highly targeted segments often perform best, you also need sufficient audience size to generate meaningful results from your campaigns.

Naming and Organization Conventions

Clear naming conventions make segment management dramatically easier as your strategy grows. Adopt a consistent naming system that instantly communicates each segment’s purpose and criteria.

1. Include key criteria in the name (e.g., “Purchased Last 30 Days – No Email Opens”)
2. Add date references when appropriate (e.g., “Holiday 2024 Shoppers”)
3. Use prefixes to group related segments (e.g., “ENGAGEMENT: High” and “ENGAGEMENT: Low”)
4. Document complex segment definitions in a central location for team reference
5. Review and archive outdated segments quarterly to maintain a clean workspace

Following these naming practices ensures anyone on your team can quickly understand each segment’s purpose without needing to examine the specific conditions. This clarity becomes increasingly valuable as your segmentation strategy grows more sophisticated.

Testing and Refining Your Segments

Segment testing helps you determine which audience groupings deliver the best results. This iterative process allows you to continuously improve your targeting precision over time.

Start by creating variation segments with slightly different criteria, then send identical campaigns to each group and compare performance. For example, test whether “Purchased in last 30 days” or “Purchased in last 60 days” generates better engagement and conversion rates.

Monitor key metrics for each segment, including:

• Open rates and click-through rates
• Conversion rates and revenue per recipient
• Unsubscribe rates and spam complaints

Use these performance insights to refine your segment definitions, gradually improving their effectiveness. Remember that segmentation is an ongoing process of optimization rather than a one-time setup.

Avoiding Common Segmentation Mistakes

Even experienced marketers sometimes make segmentation errors that undermine their results. Awareness of these common pitfalls helps you avoid them in your own segmentation strategy.

The most frequent segmentation mistakes include:

• Creating overly narrow segments with too few contacts
• Using too many segments, making campaign management unwieldy
• Neglecting to update segment criteria as business needs change
• Misusing AND/OR operators, resulting in unexpected audience selection
• Failing to test segment performance against broader audiences

Avoiding these errors requires careful planning and regular review of your segmentation strategy. Take time to validate that each segment contains the expected contacts before launching campaigns, and periodically audit your segments to ensure they still align with your marketing objectives.

Maximizing Your Segmentation Success

Maximizing segmentation success requires thinking beyond basic targeting to create a comprehensive strategy. This approach ensures your segments work together cohesively to support your overall marketing goals.

Successful segmentation strategies evolve alongside your business needs. As your customer base grows and your marketing objectives change, your segmentation approach should adapt accordingly to maintain optimal performance.

The most effective segmentation strategies connect seamlessly with your broader marketing ecosystem. By integrating your segments with automated flows, personalized content, and cross-channel campaigns, you can create a cohesive customer experience that drives exceptional results.

Integrating Segments with Automated Flows

Segments reach their full potential when integrated with automated marketing flows. This powerful combination creates personalized customer journeys that respond dynamically to changing behaviors and preferences.

To effectively connect segments with flows:

1. Use segments as flow triggers to automatically start personalized sequences
2. Incorporate segment conditions in flow filters to control who receives specific messages
3. Create segment-specific content variations within flows for maximum relevance
4. Set up exit criteria based on segment changes to ensure timely flow completion
5. Regularly review flow performance by segment to identify optimization opportunities

For example, you might create a win-back flow triggered when customers enter your “At-Risk – No Purchase in 60 Days” segment. The flow could automatically end if they make a purchase and leave the segment, ensuring they never receive irrelevant messages.

Measuring Segment Performance

Regular performance measurement helps you identify your most valuable segments and refine your targeting strategy. Tracking key metrics for each segment provides insights that drive continuous improvement.

Focus on these critical performance indicators:

• Revenue per recipient (total revenue divided by number of recipients)
• Conversion rate (percentage of recipients who completed desired actions)
• Engagement metrics (open rates, click rates, and site visits)
• List health metrics (unsubscribe rates and spam complaints)
• Growth/decline rates (how quickly segments gain or lose members)

Compare these metrics across different segments to identify which audience groups deliver the highest return on investment. This analysis helps you allocate resources effectively, focusing your marketing efforts on the segments that generate the greatest business impact.

Taking Your Klaviyo Segmentation Further

Advancing your segmentation strategy requires looking beyond basic targeting to implement sophisticated approaches. As you grow more comfortable with Klaviyo’s segmentation capabilities, you can explore advanced techniques that deliver even better results.

Continuous learning plays a crucial role in segmentation success. Staying current with Klaviyo’s evolving features and industry best practices ensures your segmentation strategy remains effective in a changing marketing landscape.

Exploring Predictive Analytics Segments

Predictive analytics segments leverage artificial intelligence to forecast future customer behavior. These powerful segments help you proactively address customer needs before they explicitly signal their intentions.

Klaviyo offers several predictive properties you can use in segmentation:

• Predicted customer lifetime value (CLV)
• Churn risk score
• Expected date of next order
• Predicted average order value

By incorporating these predictive metrics into your segments, you can identify high-value customers before they make large purchases or intervene with at-risk customers before they abandon your brand. This proactive approach dramatically improves marketing efficiency by focusing resources where they’ll have the greatest impact.

Building Cross-Channel Segmentation Strategies

Cross-channel segmentation extends your targeting beyond email to create consistent experiences across all customer touchpoints. This comprehensive approach ensures your messaging remains relevant regardless of how customers interact with your brand.

Effective cross-channel segmentation strategies:

• Sync Klaviyo segments with social media platforms for targeted advertising
• Use segment data to personalize on-site experiences and product recommendations
• Coordinate SMS and email messaging based on channel preferences
• Align in-store experiences with digital segments for loyalty program members
• Create consistent messaging themes across all channels for each segment

This integrated approach creates a seamless customer experience while maximizing the impact of your marketing investment. By maintaining consistent targeting across channels, you reinforce your messaging and improve overall campaign performance.
