How to Segment Klaviyo: Build Revenue-Driving Audiences 2026
TL;DR
A segment in Klaviyo is a dynamic group of profiles that automatically updates based on conditions you define, like purchase behavior, email engagement, or location. Unlike static lists, segments grow and shrink in near real time as customers meet or fall out of your criteria. Segmented campaigns return 3x the revenue per recipient compared to unsegmented sends. Getting segmentation right is one of the single highest-impact things you can do inside Klaviyo.
If you’re new to the platform, start with our complete guide to Klaviyo for broader context.
What Is a Segment in Klaviyo?
A segment in Klaviyo is a dynamic grouping of profiles defined by a set of conditions you choose. Think of it as a living filter applied to your entire contact database. Once you set the rules, Klaviyo continuously adds profiles that match and removes profiles that no longer qualify.
This is the critical word: dynamic. A Klaviyo segment is not a fixed snapshot. It updates in close to real time after a customer takes a qualifying action, whether that’s placing an order, opening an email, or visiting a product page.
When you create a segment, it pulls members from all people in your account based on the definition you establish. You set conditions once. After that, profiles move in and out automatically based on whether their behavior and attributes match your criteria.
This matters because it means your targeting stays current without manual upkeep. A “purchased in last 30 days” segment today will contain different people than it did last month, and that happens without you touching it.
Segment vs. List: The Key Difference
This distinction trips up more Klaviyo users than almost anything else.
List | Segment | |
|---|---|---|
Type | Static | Dynamic |
Purpose | Consent and entry point | Targeting logic |
How profiles join | Manual add, signup form, import | Automatically, based on conditions |
Updates | Only when you add or remove someone | Near real time |
Lists represent how someone entered your world and gave consent. Segments represent how you target them based on what they’ve done since. As one practitioner put it on Joy Joya’s blog: “Lists should represent entry and consent. Segments should represent targeting logic.”
Confusing them creates real problems. It affects who gets your emails, how flows trigger, and whether your reporting makes any sense. One important gotcha: segments pull from everyone in your account unless you constrain them to a specific list. That means you could accidentally email people who never opted in to marketing messages.
For a deeper breakdown, see our dedicated Klaviyo list vs segment comparison.
Types of Segment Conditions
Klaviyo’s segment builder gives you five main categories of conditions to work with.
1. What Someone Has Done (or Not Done)
This is behavioral segmentation, the most powerful type. You can filter by any event Klaviyo tracks: Placed Order, Opened Email, Clicked SMS, Viewed Product, Started Checkout, and dozens more. Each event condition supports up to 10 filters, so you can get specific (e.g., “placed order where product name contains ‘serum’ at least 2 times in the last 90 days”).
2. Properties About Someone
These are profile attributes: first name, custom properties from your Shopify integration, tags, or anything you’ve manually added. Useful for demographic or preference-based targeting.
3. Where Someone Is Located
Klaviyo supports location-based segmentation. For customers in the US, EU, Australia, New Zealand, or Canada, you can segment by a radius around a specific zip code. Helpful for local events, regional promotions, or shipping zone targeting.
4. Whether Someone Is in a List or Segment
This lets you combine existing groups. You can build meta-segments like “in my VIP segment AND in my email newsletter list,” which is exactly how you constrain segments to opted-in contacts.
5. Predictive Analytics
Klaviyo’s machine learning generates predictions for Customer Lifetime Value (CLV), churn risk, and expected next order date. These require sufficient order history (typically 500+ orders in your store), but they let you target customers based on where they’re headed, not just where they’ve been.
A single segment supports a maximum of 100 conditions. There’s also an account-level cap on total lists and segments, though most brands won’t hit it.
For more on building a complete segmentation strategy, we cover the tactical playbook separately.
How to Create a Segment in Klaviyo
The process is straightforward:
Navigate to Audiences > Lists & Segments
Click Create List / Segment, then choose Segment
Name your segment something descriptive (e.g., “Engaged 90d, Purchased 2+”)
Add conditions using the builder, combining them with AND/OR logic
Preview the segment to verify the audience size and composition
Click Create Segment
The segment immediately begins populating and will continue updating as profiles match or stop matching your conditions.
Using Segments AI
Klaviyo now lets you describe your desired audience in plain English, and the AI translates it into segment conditions. Type something like “customers who bought twice in the last 6 months but haven’t opened an email in 30 days,” and the builder generates the matching rules.
This feature requires a paid Klaviyo account. Practitioners report it’s genuinely useful for quickly drafting segments, though you should always review the generated conditions before saving. For more on AI capabilities in email marketing, check out our guide to AI tools for ecommerce email.
Essential Segments Every Ecommerce Brand Needs
Most brands need five to eight core segments as a foundation. Here are the ones that matter most.
VIP Customers. Your top 10% by revenue or purchase frequency. According to Top Growth Marketing’s analysis of RFM data, these “Champions” (5/5/5 scores) drive 30-40% of revenue from just 5-10% of your customer base. They deserve different treatment. Our VIP email marketing strategy guide covers this in detail.
Engaged Subscribers. People who have opened or clicked an email in the last 30, 60, or 90 days. These are your safest send targets and your deliverability anchors.
Unengaged Subscribers. No opens in 90+ days, never purchased. Practitioners on the Klaviyo Community forum consistently recommend sending this group no more than one campaign per month. Excluding them from most sends protects your email deliverability.
Recent Purchasers (0-30 days). Fresh buyers in the post-purchase honeymoon phase. Perfect for cross-sells, review requests, and brand education.
At-Risk Customers (60-180 days since last purchase). These people bought from you but are drifting. A well-timed three-email win-back sequence with a compelling offer can recover 10-15% of this group before they go fully dormant.
Product-Specific Buyers. Customers who purchased a specific product or category. Essential for targeted cross-sell campaigns and new product launches in the same category.

Why Segments Drive More Revenue
The data on Klaviyo segmentation is unambiguous. Highly segmented campaigns return more than 3x the revenue per recipient compared to unsegmented campaigns. Klaviyo Academy’s own guidance states that sending at least two-thirds of your campaigns to segments rather than lists will help you get the most out of the platform.
The revenue gap gets even wider with automation. Behavioral flows, which are inherently segmented, generate 41% of total email revenue from just 5.3% of sends, with revenue per recipient nearly 18x higher than campaigns. The top 10% of email flows achieve RPR as high as $7.79 and click rates over 10%, according to Klaviyo’s 2026 email benchmarks.
The reason is simple. Sending the right message to the right person at the right time beats blasting everyone with the same thing. Every time. If your email revenue feels stuck, the problem is almost always that you’re sending bulk emails instead of segmented ones.

Advanced Features: RFM, Predictive Analytics, and Snapshots
RFM Analysis
Klaviyo’s RFM (Recency, Frequency, Monetary) report scores customers on how recently they purchased, how often they buy, and how much they spend. This creates natural lifecycle groups: Champions, Loyal, At Risk, Needs Attention, and others. You can build segments directly from these RFM groupings, which gives you a purchase-behavior framework rather than relying solely on open rates.
Practitioners on the Klaviyo Community forum note that many users plateau at basic engagement segments. RFM-based segmentation is the next level that most ecommerce brands skip.
Predictive Analytics in Segments
Klaviyo’s three most useful predictive properties for segmentation are:
Predicted CLV: Projects each customer’s future value. You can build a “high predicted CLV” segment and treat those customers like VIPs before they’ve hit that spending threshold.
Churn Risk: Flags customers likely to lapse before it actually happens. Brands activating this feature typically recover 12-18% more at-risk customers compared to time-based win-back triggers alone.
Expected Next Order Date: Lets you time campaigns to arrive right when a customer is likely ready to reorder.

Segment Snapshots
Sometimes you need a static version of a dynamic segment. Klaviyo’s snapshot feature lets you freeze a segment at a specific moment in time, creating a new list containing all current members. The original segment keeps updating dynamically, but the snapshot stays fixed. This is useful for one-time promotions, A/B test holdout groups, or compliance documentation.
Cross-Channel Segments: Beyond Email
A Klaviyo segment isn’t just for email. The same segment definitions apply across SMS, push notifications, and even social ad syncing. Build a segment once, and you can target those same profiles in a Klaviyo SMS flow, sync them to Facebook Custom Audiences, or trigger push notifications.
This cross-channel capability is one of the reasons practitioners on Shopify app reviews (4.6 stars, 2,570+ reviews) consistently highlight Klaviyo’s segmentation. One reviewer from The Autism Helper noted the tools are “key for our business to be able to properly segment our audience to offer personalized messaging due to the native integration with Shopify.”
For a full walkthrough of Klaviyo’s SMS capabilities, we cover setup and pricing in a separate guide.
Common Segmentation Mistakes to Avoid
Sending to full lists instead of segments. This is the most expensive mistake, both in terms of revenue left on the table and deliverability damage. Klaviyo’s own benchmarks confirm that segmented sends outperform list sends by 3x on revenue per recipient.
Not excluding unengaged subscribers. Every campaign you send to people who never open drags down your sender reputation. Create an unengaged segment (no opens/clicks in 90+ days, never purchased) and exclude it from most sends.
Forgetting to constrain segments to a list. If your segment doesn’t include a “member of [your email list]” condition, it pulls from every profile in your account, including people who never consented to marketing emails.
Ignoring the cost implications. Capterra reviewers frequently mention that Klaviyo charges based on total profiles, not just active ones. Smart segmentation paired with regular list cleaning directly controls your bill. Unused profiles sitting in your account cost real money every month.
Over-relying on open-based segments. Open rates became less reliable after Apple’s Mail Privacy Protection. Building your segmentation framework around purchase behavior and RFM data gives you signals that actually correlate with revenue, not just inbox activity.
Frequently Asked Questions
How often do Klaviyo segments update?
Segments process updates in near real time. When a customer takes a qualifying action (places an order, opens an email), the segment reflects that change shortly after. During periods of high platform traffic, minor delays can occur.
Can I use a segment to trigger a Klaviyo flow?
Yes. Segments can serve as flow triggers. When a profile enters a segment, that entry event can kick off an automated sequence. This is common for win-back flows, VIP welcome sequences, and churn prevention automations. See our guide to the best Klaviyo flows for specific examples.
What’s the maximum number of conditions per segment?
A single segment supports up to 100 conditions, and each event-based condition can have up to 10 filters. There’s also an account-level limit on total lists and segments, though Klaviyo doesn’t publish the exact number publicly.
Are segments the same across email and SMS in Klaviyo?
Yes. A segment you create works across all channels in Klaviyo, including email, SMS, push, and ad platform syncing. You don’t need to rebuild segments for different channels.
What’s the difference between a segment and a segment snapshot?
A segment is dynamic and continuously updates. A snapshot freezes the segment membership at a single point in time into a static list. The original segment keeps updating after you take the snapshot.
Do I need a paid Klaviyo account to use Segments AI?
Yes. The AI-powered natural language segment builder is only available on paid plans.
How does Klaviyo segmentation affect my bill?
Klaviyo prices based on total active profiles in your account, not how many you email. Keeping unsegmented, unengaged profiles inflated in your database means paying for contacts you’re not monetizing. Regular suppression segment hygiene keeps costs down.
Can I segment Klaviyo contacts by Shopify data?
Absolutely. Klaviyo’s native Shopify integration syncs order data, product information, customer tags, and browsing behavior. You can segment by specific products purchased, total spend, Shopify customer tags, and more. Learn how to connect Klaviyo with Shopify if you haven’t set up the integration yet.
