Instead of manually configuring every condition, you can now describe the audience you're looking for in plain English, and Klaviyo's AI will translate that into a working segment - ready to review, refine, and use. How to Use Klaviyo's AI-Powered Segment Builder | warbble·digital Klaviyo - Email Marketing # How to Use Klaviyo's AI-Powered Segment Builder to Find Your Best Customers Faster If you've ever spent an afternoon wrestling with segment conditions in Klaviyo - stacking filter after filter, second-guessing your logic, only to end up with an audience that feels a bit off - you're going to love what they've been building. This post walks you through exactly how it works, where it shines, and how to get the most out of it. 35% Typical open rate lift when moving from broad blasts to precision-segmented campaigns 30min Average time saved per segment build using AI vs. manual condition stacking Real-time Klaviyo segments update dynamically as your customer data changes - no manual refreshing The Basics ## What Is the AI-Powered Segment Builder? Klaviyo introduced natural language segmentation as part of their broader push to bring AI-driven tools into everyday marketing workflows. Rather than building segments by manually selecting properties and operators, you type a plain-language description of your target audience and Klaviyo generates the segment conditions for you. It's worth being clear: the AI isn't making marketing decisions for you. It's translating your intent into Klaviyo's segment logic. You still review, approve, and refine the output. Think of it as a very capable assistant that handles the technical heavy lifting - while you stay in control of the strategy. **Quick tip.** This feature is available on Klaviyo's standard plans and above. If you can't see it yet, check your plan tier or reach out to Klaviyo support directly. Why It Matters ## Why Good Segmentation Is the Highest-Leverage Activity in Email Marketing The difference between a segment built with real precision and a rough approximation can be the difference between a 35% open rate and a 15% one - and between nurturing a loyal customer and landing in the promotions tab. The problem has always been the gap between what marketers know and what they can build. Most people can articulate their ideal audience in a sentence. Far fewer can translate that into a nested set of Klaviyo conditions without it taking thirty minutes and three attempts. The AI segment builder closes that gap - making sophisticated segmentation accessible for anyone managing a Klaviyo account, not just specialists. Average open rate by segmentation approach Open rate comparison by segmentation method. Broad blast (no segmentation) Basic list segmentation Behaviour-based segments AI-powered precision segments Step by Step ## How to Use the AI Segment Builder Here's the exact process from start to a live, dynamic segment - including where your expertise still matters most. 01 #### Navigate to the Segment Builder Head to Lists & Segments in your Klaviyo account and click Create Segment. You'll land in the familiar segment editor - but now you'll notice a new option at the top: "Describe your segment" or a similar AI prompt field, depending on which version of the interface you're on. 02 #### Describe Your Audience in Plain Language This is where it gets genuinely interesting. Type a description of the audience you want to reach. Be as specific as you can - the more detail you give, the more accurate the output. You can reference purchase history, engagement behaviour, spend thresholds, time windows, and even predictive properties like churn risk or predicted LTV. 03 #### Review the Generated Conditions Klaviyo will generate a set of segment conditions based on your description. Don't just hit save - take a moment to review them. Check that the logic matches your intent, that the operators (at least, exactly, is not) are correct, and that the time windows make sense for your send frequency. This is where your expertise still matters most. The AI handles the translation - you handle the strategy. 04 #### Preview and Refine Use the Preview option to see how many profiles your segment currently includes. If the number looks too high or too low, adjust the conditions manually or try rephrasing your description. A well-built segment typically has a clear, defensible rationale - if you can't explain in one sentence why someone belongs in that audience, it's worth tightening the logic. 05 #### Name, Save, and Use Give your segment a name that makes sense to anyone on your team - not just you right now, but future-you and your colleagues. Something like "New Customers - No Second Purchase (60 Days)" beats "Segment April 2026" every single time. Once saved, your segment is live and dynamic - it will update automatically as your customer data changes. Prompt Examples ## Prompts That Work Well The quality of your prompt directly affects the quality of your segment. Here are examples that consistently produce accurate, useful results. Win-back "Customers who placed their first order in the last 60 days and haven't purchased again" VIP actives "VIP customers who've spent over £500 in the last 12 months and are active email openers" Engaged non-buyers "Subscribers who clicked a link in the last campaign but didn't purchase within 7 days" Lapsed buyers "Lapsed customers - last purchase over 6 months ago, previously bought at least twice" Unengaged "Subscribers with no email opens or clicks in the last 90 days who joined more than 6 months ago" Predictive LTV "Customers with high predicted lifetime value who haven't purchased in the last 45 days" Where to Start ## Five High-Value Segments to Build First Not sure which segments to prioritise? These five audiences consistently deliver the highest ROI across Klaviyo accounts - and all five translate well into AI prompt descriptions. | Segment | Why It Matters | Best Used For | | --- | --- | --- | | Win-back candidates | Lapsed customers with 2+ previous purchases - your most recoverable churned buyers | Targeted re-engagement campaigns with a time-limited incentive | | Post-first-purchase non-repeaters | New customers who haven't returned within 45-60 days - highest churn risk window | Second purchase nudge flows with product recommendations | | Engaged non-buyers | Consistent openers and clickers who've never converted - qualified but unconvinced | Social proof-heavy campaigns, offer-led conversion push | | High-value actives | Top spenders still engaging - your most valuable relationships to protect | VIP treatment, early access, loyalty programmes | | Unengaged subscribers | 90+ days of no engagement - candidates for sunset or re-engagement before they hurt deliverability | Last-chance re-engagement campaign, then suppression | **Worth knowing.** Klaviyo's predictive analytics - including predicted customer lifetime value and churn risk - can also be referenced directly in your natural language prompts. This makes segments even more powerful when combined with AI, letting you act on future behaviour rather than just past actions. Healthcheck ## Is Your Klaviyo Segmentation Working Hard Enough? #### Doing It Well You have distinct segments for new, active, lapsed, and unengaged customers Segments are named clearly and consistently across the team You're using behavioural data - opens, clicks, purchases - not just list membership Predictive properties (LTV, churn risk) are informing at least some segments Unengaged subscribers are being sunset or re-engaged on a regular cadence Open and click rates sit consistently above 30% and 3% respectively #### Warning Signs Most sends go to your full list with minimal or no segmentation Segments haven't been reviewed or updated in more than 3 months You don't have a defined win-back or lapsed customer segment Unengaged subscribers are still receiving every campaign Open rates have been declining over the last 2-3 months You've never used predictive data to inform a segment or flow Revenue contribution by segment type - typical Klaviyo account Revenue by segment type. VIP actives Post-purchase sequences Win-back campaigns Engaged non-buyers Other Common Questions ## Frequently Asked Questions Does the Klaviyo AI segment builder work for SMS as well as email? ▾ Yes - segments in Klaviyo apply across channels. A segment you build with the AI tool can be used for email campaigns, SMS sends, or both. The segment logic is channel-agnostic, so you build it once and use it wherever it's relevant to your programme. Can I edit the conditions after the AI generates them? ▾ Absolutely. The AI-generated conditions are fully editable. You can adjust operators, change time windows, add or remove conditions, and refine the logic just as you would with a manually built segment. Think of the AI output as a first draft - always worth reviewing before you save and use it. Is the AI segment builder available on all Klaviyo plans? ▾ AI features in Klaviyo are typically available on paid plans, though the specific tier requirements can change as they roll out updates. Check your account or Klaviyo's pricing page for the most current information. If you can't see the prompt field in your segment builder, your plan tier is the first thing to check. How often does a dynamic segment update? ▾ Klaviyo segments update in real time as your data changes. When a customer meets or no longer meets the segment conditions, they'll be added or removed automatically. This means your segment is always current without any manual intervention - which is particularly important for time-sensitive conditions like "purchased in the last 30 days". What if the AI generates conditions that don't match my intent? ▾ Try rephrasing your prompt with more specific language - include exact time windows, spend thresholds, and behavioural actions. If the output still isn't right, edit the conditions manually and save. The more you use the tool, the better you'll get at writing prompts that produce accurate first-pass results. It's a skill worth developing. Klaviyo Partner ### Not Sure If Your Klaviyo Setup Is Working Hard Enough?
