AI is an integral part of Klaviyo, offering significant advantages for eCommerce businesses.
However, our experience across over 100 Klaviyo accounts at Magnet Monster indicates that many brands and agencies are only using a fraction of its potential.
While flows and campaigns are common, the built-in intelligence that can enhance timing, targeting, and overall performance is often overlooked.
This guide provides a detailed breakdown of Klaviyo’s 11 core AI-powered features, along with practical eCommerce applications, clear explanations of their impact, and direct links to their location within the platform.

Understanding Klaviyo AI: Three Core Areas
Klaviyo’s AI functionalities are strategically organized into three key areas:
- Prediction: Enabling you to anticipate customer behavior, such as their next purchase date and potential lifetime value.
- Personalization: Facilitating dynamic adjustments to your communication – timing, content, and offers – tailored to individual subscribers.
- Automation: Streamlining your workflow by assisting with content creation, email A/B testing, and continuous optimization, freeing up time for strategic initiatives.
Proficiently using these AI tools is a crucial factor differentiating effective email marketing from truly exceptional, revenue-generating customer engagement.
The 11-Point Checklist for Optimizing Your Klaviyo Strategy:
1. Smart Send Time Optimization: Deliver at the Optimal Moment
Klaviyo’s AI analyzes individual subscriber engagement patterns to automatically send campaigns when they are most likely to open.
Why it matters: Move beyond standard send times. Delivering at optimal times can significantly improve open rates (often by 10-20% or more) and enhance click-through rates without increasing list fatigue or appearing intrusive.
How to use it: When scheduling a campaign, activate the "Send at recipient’s optimal time" option. Klaviyo's algorithms will manage the timing.

2. Predictive Analytics: Gain Deeper Customer Insights
Klaviyo uses historical data to forecast essential customer attributes:
- Customer Lifetime Value (LTV): Predicts the total revenue a customer is likely to generate.
- Predicted Gender: Estimates the subscriber's gender based on purchase history and engagement.
- Next Expected Order Date: Forecasts when a customer is likely to make their next purchase.
Use cases:
- Winback Flows: Initiate targeted winback emails or SMS messages for customers whose predicted next order date has passed.
- Personalized Content: Segment your audience by predicted gender to customize product recommendations and messaging (e.g., promoting specific product lines).
- VIP Segmentation: Identify and prioritize high-LTV customers with exclusive offers and early access, fostering stronger loyalty.

3. AI Subject Line Assistant: Improve Open Rates with Data-Driven Suggestions
If you need help crafting effective subject lines, Klaviyo’s AI can generate 3-5 diverse options based on your email content and proven best practices.
Why it matters: Subject lines are critical for email engagement. The AI Assistant offers a quick and efficient way to create multiple variations for A/B testing, helping you identify the most compelling language and increase open rates, especially when time is limited or managing large-scale email programs.

4. Personalized Product Recommendations: Display Relevant Products Automatically
Within emails and flows, you can integrate dynamic product recommendation blocks that automatically populate with products most relevant to each subscriber based on their past behavior, browsing history, and purchase patterns.
Why it matters: Enhance relevance, increase clicks, and drive sales without manual product tagging or segmentation. This feature ensures subscribers see products aligned with their interests.
Use it in:
- Cart Abandonment Flows: Show the exact items left in their cart alongside related products.
- Post-Purchase Flows: Recommend complementary items or products from the same category.
- Winback Flows: Feature popular items or new arrivals to re-engage inactive customers.
- Replenishment Flows: Suggest previously purchased products, timed around their predicted repurchase window.

5. Predictive Replenishment Timing: Proactive Re-engagement for Repeat Purchases
Utilize Klaviyo’s "Predicted Next Order Date" property to send timely reminders via email or SMS before customers are likely to need to repurchase frequently bought items, effectively reducing churn.
Example:
- Supplement Brand: Send an SMS reminder around day 25 for a 30-day supply of protein powder.
- Cosmetics Retailer: Trigger an email on day 40 with a restock reminder for a 60-day supply of their preferred serum.
Why it works: This proactive strategy intercepts potential churn by reminding customers to repurchase when it’s most convenient, often before they actively think about it, providing an advantage over solely relying on retargeting efforts.

6. Smart List Cleaning and Churn Prediction: Maintain an Engaged Subscriber Base
Klaviyo's AI continuously analyzes each subscriber's engagement level and predicts their likelihood of becoming inactive. This enables the creation of intelligent suppression and winback segments.
Use cases:
- Suppression Segments: Automatically exclude low-engagement profiles from promotional sends, improving deliverability and optimizing sending costs.
- Proactive Winback: Initiate targeted winback campaigns for valuable subscribers showing signs of disengagement before they become completely inactive.
Pro tip: Develop segments based on users "Likely to churn in the next 30 days" and implement specific re-engagement tactics to retain valuable customers and protect LTV.

7. Create Dynamic and Personalized Customer Journeys
Implement logic within your flows based on Klaviyo's predictive properties to create highly personalized customer experiences.
Examples:
- Upselling: "If predicted LTV is over $250, present a bundle upsell offer."
- Content Personalization: "If predicted gender is female, display product images featuring female models."
- Offer Optimization: "If a customer is likely to reorder soon, remove the discount step in the replenishment flow to maximize margin."
Why it works: This behavioral logic ensures your messaging and offers are highly relevant to each individual, leading to improved conversion rates compared to standard, non-personalized flows.

8. Benchmarking Engine (AI-Powered Data Comparisons): Understand Your Performance Relative to Your Industry
Klaviyo aggregates performance data from numerous sends within your sector, providing valuable benchmarks to assess your results.
You get:
- Open and click rate comparisons against your industry averages.
- Insights into bounce and unsubscribe trends.
- Flow-level performance comparisons, allowing you to evaluate your automation effectiveness.
Use case: Instead of speculating about the quality of a 38% open rate, Klaviyo's benchmarks will indicate if it's above, below, or average for eCommerce businesses in your specific industry, enabling data-driven optimization.

9. AI-Enhanced Signup Form Targeting: Optimize Initial Customer Acquisition
Klaviyo's signup forms can intelligently display different messages and offers based on various visitor behaviors, session history, and location.
Examples:
- New Visitor Incentive: A first-time visitor might see a pop-up offering a signup discount.
- Loyalty Focus: A returning user who hasn't purchased recently might see a call to action highlighting your loyalty program benefits.
- Cart Abandonment Recovery: A visitor who abandoned their cart might see a form offering a small incentive to complete their purchase.
Why it matters: This AI-driven personalization begins at the initial interaction, improving conversion rates and building a more engaged email list from the start.

10. SMS Send Time Optimization: Deliver Text Messages at the Right Time
For accounts using Klaviyo SMS, this beta feature extends smart send time optimization to text messages, ensuring your SMS campaigns are delivered when subscribers are most likely to engage.
Why it matters: Avoid sending SMS messages at inconvenient times, which can lead to lower engagement and higher opt-out rates. Optimizing send times improves click-through rates and reduces subscriber churn.
How to check: This feature is typically enabled via the "Smart Send Time" option within the SMS campaign builder (availability may vary based on your account's beta access).

11. Auto-Generated Email Content: Accelerate Email Creation Processes
Klaviyo Labs is testing innovative AI-powered tools designed to assist with writing and building emails more efficiently.
Includes:
- Smart Block Suggestions: AI-driven recommendations for email layouts and content blocks based on your campaign objectives.
- Copy Generation for Welcome Flows: AI assistance in drafting effective welcome email content.
- Dynamic Layout Previews: Intelligent previews of how your email will render across different devices.
Note: As this is an early beta feature within Klaviyo Labs, availability and functionality may be limited and subject to change. However, it indicates the potential for AI to streamline email creation, allowing for quicker generation of initial drafts and concepts.
