Do you ever get the feeling that a website, email, or pop-up just “gets” you? Like it knows exactly what you’re looking for, before you even finish typing?
That’s ecommerce personalization at work, and it’s why you're more likely to buy from brands that remember your preferences, recommend products based on your behavior, and treat you like an individual instead of website traffic.
According to Klaviyo's 2025 Future of Consumer Marketing Report, 74% of consumers expect brands to provide more personalized experiences, and 66% expect brands to make them feel valued and understood.
Ecommerce personalization tools use customer data like browsing behavior, purchase history, location, and preferences to meet those kinds of expectations and customize the shopping experience. These platforms dynamically adjust product recommendations, search results, homepage content, and more based on individual behavior.
By integrating your B2C CRM with ecommerce personalization tools, you can create consistent, data-driven experiences across channels to turn one-time browsers into repeat customers.
How do ecommerce personalization tools help marketers reach their goals?
Generic product pages and blanket recommendations leave money on the table. Ecommerce personalization tools fix that by showing each shopper exactly what they’re most likely to want.
Here’s how personalizing the ecommerce shopping experience improves marketing outcomes:
- More subscribers: Personalized recommendations are one of the top 3 reasons consumers sign up for ongoing updates from retail or ecommerce brands, according to our Future of Consumer Marketing Report.
- Higher conversion rates: When shoppers see products that match their preferences and behavior, they're more likely to complete a purchase. When deciding which ecommerce brand to purchase from, 1 in 6 consumers say personalized product suggestions based on their needs or interests influence their decisions, according to our Future of Consumer Marketing Report.
- Bigger cart sizes and fewer abandoned carts: When people see personalized up- and cross-sells that match what they're already browsing or buying, they're more likely to add more items to their cart and less likely to leave empty-handed. Curated experiences like these translate to sales: according to research from Deloitte, brands that are great at personalization are 48% more likely to surpass their revenue goals.
16 of the best ecommerce personalization tools
The right ecommerce personalization tools integrate with your existing tech stack so they have access to as much customer data as possible. Here are 16 ecommerce personalization tools that work with your CRM to help you create and automate shopping experiences customers want:
Giftnote
Giftnote powers branded gift messages, e-gift cards, and store credit to customers the moment gifts arrive. It tracks interactions, like when someone opens or redeems a gift, so you can follow up with both senders and recipients at important moments.
To turn gift purchases into personalized experiences that keep customers coming back, Klaviyo’s Giftnote integration lets you:
- Instantly respond to actions like gift opens, clicks, or redemptions by triggering gift-related flows.
- Segment customers by gifter and recipient behavior and track gift-driven revenue in real time.
- Send personalized, branded messages via Klaviyo when a gift is delivered.
LaunchPad by LiftEngine
LaunchPad by LiftEngine enriches your customer profiles with the kind of data you can’t get from purchase history alone: things like gender, age, income, and household composition. It’s the difference between knowing someone bought a candle and knowing they’re a 35-year-old homeowner with kids who probably wants home goods and not singles’ night bar accessories.
Using Klaviyo's LaunchPad integration, you can use this new demographic information anywhere—your customer data platform for advanced insights, for example, or social platforms like Meta to build custom audiences.
With Klaviyo and LaunchPad, you can also:
- Create even more niche segments based on ecommerce, loyalty, and review integration data.
- Get access to LaunchPad’s database of 250 million US consumers to grow your customer list.
Nosto
Nosto unifies your marketing and product data so you can personalize both what happens on your website and what lands in your customers' inboxes. It uses AI to adjust product recommendations, search results, and category pages based on each shopper's behavior. Think of it like a smart assistant that doesn’t require a developer to build custom features.
Using Klaviyo’s Nosto integration, you can:
- Sync customer segments from Nosto to Klaviyo to power targeted ecommerce campaigns.
- Import Klaviyo lists to personalize on-site banners and recommendations.
- Trigger abandonment flows when someone searches but doesn’t buy.
- Drop personalized product recommendation blocks straight into your emails.
Tea maker Harney & Sons needed to target their sign-up CTAs to the subscribers they wanted—specifically, mobile web visitors who hadn’t yet signed up for email. With Klaviyo SMS and the Nosto integration, they were able to target only un-cookied mobile web visitors with SMS sign-up pop-ups.
Rebuy
Rebuy uses AI and machine learning to suggest smart product recommendations across the ecommerce experience, driving up- and cross-sells at key moments like cart, check-out, and post-purchase. A customer who buys beard oil might see a discounted beard comb in their cart, while someone buying skincare gets serum recommendations—all automatically matched to their purchase.
To grow your subscriber list and boost conversions across the customer lifecycle, use Klaviyo’s Rebuy integration to:
- Personalize on-site offers based on customer segments.
- Capture high-intent shoppers’ phone numbers in the cart to grow your text message subscriber list while shoppers are already engaged.
- Recommend products in flows or your customer account pages based on “order placed” triggers.
- Feature customer ratings and reviews in personalized product recommendations.
Men’s personal care product brand Every Man Jack relies on an ecosystem of integrations to create a hyper-personalized experience for DTC shoppers. For example, they send AI-powered re-stock reminders triggered by customers’ predicted next order date that include links to a pre-filled Rebuy cart.
Swym Wishlist Plus
According to research from bizrate insights, over 30% of people use wishlists to save items for the future. Swym engages shoppers with wishlists, save-for-later buttons, and back-in-stock reminders that brands can use to personalize the ecommerce experience.
You can use Klaviyo’s Swym Wishlist Plus integration to bring wishlist data into your marketing activities and drive more revenue by:
- Automatically nudging shoppers about items they’ve saved
- Sending wishlist, price drop, or back-in-stock mobile notifications via Klaviyo using Tapcart
- Triggering emails or text messages when wishlist items are on sale
When lifestyle brand POPFLEX wanted to modernize their holiday strategy, they leaned on browsing data, purchasing data, and wishlist data from Klaviyo’s Swym integration to send more targeted, timely messages and stand out in the inbox.
The strategy involved running a shopping spree giveaway that required entrants to create holiday wishlists on the POPFLEX site. Nearly 100,000 customers entered, which gave them tons of browsing and wishlist data from Swym to use for targeted holiday messaging.
Athos Commerce
Athos Commerce (previously Searchspring) gathers customer behavioral data and uses machine learning to display hyper-relevant products throughout your website, marketplaces, and social channels. Rather than showing everyone the same bestsellers, it shows each person what they’re most likely to actually buy.
To make product discovery smarter, Klaviyo's Athos Commerce integration allows you to:
- Upload customer shopping data to create laser-focused segments for targeted messaging.
- Deliver machine learning-powered personalized product recommendations in your email and text message campaigns.
- Alert shoppers to price drops, shipping updates, and cart reminders.
Doofinder
Doofinder is an AI-powered search engine and discovery enhancer built into your website that displays text, image, or voice results quickly. The goal is to help customers find what they’re looking for more easily while they browse.
Klaviyo's Doofinder integration automatically brings that search data into your CRM so you can:
- Re-engage shoppers who searched but bailed.
- Build campaigns around what people are actually searching for, segmenting customers by interests, trending products, or specific search terms.
- Track trending searches to spot patterns and adjust your messaging before your competitors do.
Fast Simon
Fast Simon uses AI to help online stores show shoppers the right products at the right time, whether they’re searching, browsing, or checking out, so that more people buy and spend more. It analyzes a customer’s behavior, then personalizes product displays accordingly. Someone who filters by "sale," for example, consistently sees discounted items prioritized.
To make product discovery smarter, Klaviyo’s Fast Simon integration allows you to:
- Trigger intent-based flows like abandoned search flows (when someone searches for "leather boots" but doesn't buy) and abandoned browsing flows (when they view multiple products in a category but leave).
- Pull AI-powered product recommendations based on what customers specifically searched for and browsed, not just what they added to cart or purchased.
- Create segments that identify high-intent shoppers based on their search patterns and product exploration behavior.
Kimonix
Kimonix is a merchandising platform that uses AI to organize which products show up (and in which order) in your product collections, based on what will be the most profitable. It considers your inventory levels and profit margins to automatically rearrange your collections in real time, so you can push products you actually want to sell and not just what’s popular.
With Klaviyo’s Kimonix integration, you can be more efficient and drive more revenue from your ecommerce marketing by:
- Promoting personalized product recommendations
- Automating marketing messages based on inventory levels and what’s selling
- Creating collections that match customer behavior
LimeSpot
LimeSpot is a no-code AI-driven personalization platform that powers:

Use Klaviyo with LimeSpot to add tailored product recommendations based on shopper preferences and intent directly into your emails and text messages, and test and optimize campaign recommendation types based on performance metrics.
Eikona
Eikona replaces manual content creation and A/B testing with generative AI and reinforcement learning. It automatically creates, adapts, and optimizes variations of your creative assets like images, videos, and marketing content for different audiences.
With Klaviyo's Eikona integration, you can use AI testing to automatically match users with the creative variation that will resonate most with them, and scale personalization with auto-generated assets that align with your brand.
Mailability
Mailability analyzes thousands of micro-behaviors and assigns each person an "intent score" that predicts how likely they are to buy right now. It identifies which specific customers are ready to buy and which ones need to be left alone for now, so you're targeting high-intent shoppers when they’re most likely to engage instead of annoying people who aren't interested yet.
Klaviyo's Mailability integration helps you re-engage shoppers who’ve gone dormant, nudge high-intent buyers when they're ready to convert, and understand exactly how much incremental revenue you’re generating by tracking:
- Revenue generated
- Klaviyo-attributed revenue
- Number of orders
- Site activity
- Click rate
- Open rate
- Bounce rate
- Unsubscribe rate
- Spam rate
Monocle
Monocle is an AI layer that curates personalized experiences for each individual customer, deciding when to send them a message, which message to send, how many times to reach out, and whether to include a discount.
Instead of treating everyone in a "cart abandoners" segment the same way, for example, Monocle analyzes their behavior and intent to figure out that Customer A needs one nudge with no discount, while Customer B needs 3 messages ending with a 15% off code.
To get more from what you’ve already built, Klaviyo's Monocle integration:
- Adapts each flow for each customer to capture revenue that static flows leave behind
- Pinpoints high-intent audiences for campaign sends, protecting list health while driving more revenue
- Surfaces high-value segments your current set-up can’t see
