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've even finished typing?
That's ecommerce personalisation at work, and it's why you're more likely to buy from brands that remember your preferences, recommend products based on your behaviour, and treat you like an individual instead of website traffic.
UK shoppers are still waiting for most brands to get this right. Research from Retail Economics for Infobip found that over half of UK shoppers consider retailers' communications too generic, and 60% find them irrelevant. Personalisation closes that gap: businesses see consumers spend 38% more on average when their experience is personalised, according to Twilio Segment's 2024 State of Personalisation Report.
Ecommerce personalisation tools use customer data like browsing behaviour, purchase history, location, and preferences to meet those expectations and customise the shopping experience. These platforms dynamically adjust product recommendations, search results, on-site content, and messaging based on individual behaviour.
By connecting your B2C CRM with ecommerce personalisation tools, you can build consistent, data-driven experiences across channels and turn one-time browsers into repeat customers.
How ecommerce personalisation tools help marketers reach their goals
Generic product pages and blanket recommendations leave money on the table. Ecommerce personalisation tools fix that by showing each shopper what they're most likely to want.
Here's how personalising the shopping experience improves marketing outcomes:
- More subscribers: Personalised recommendations are one of the top 3 reasons consumers sign up for ongoing updates from retail or ecommerce brands, according to Klaviyo's 2025 Future of Consumer Marketing Report.
- Higher conversion rates: When shoppers see products that match their preferences and behaviour, they're more likely to complete a purchase. One in 6 consumers say personalised product suggestions influence which ecommerce brand they buy from, according to the same report.
- Bigger basket sizes and fewer abandoned baskets: When people see personalised up-sells and cross-sells that match what they're already browsing or buying, they're more likely to add more items to their basket and less likely to leave empty-handed. Curated experiences translate to sales: brands that are great at personalisation are 48% more likely to surpass their revenue goals, according to Deloitte research.
8 of the best ecommerce personalisation tools
The right ecommerce personalisation tools integrate with your existing tech stack so they have access to as much customer data as possible. Here are 8 tools that work with your CRM to help you create and automate the shopping experiences UK customers expect:
Dynamic Yield by Mastercard
Dynamic Yield is a personalisation and experimentation platform that adjusts on-site content and email based on a shopper's behaviour, affinity, geo-location, and offline purchase history.
Klaviyo's Dynamic Yield integration creates a consistent journey from your site experience to your email campaigns. Using the integration's Universal Block Connector, you can improve product discovery with Dynamic Yield's recommendation widget rendered directly inside Klaviyo emails, personalise email banners, maps, menus, and countdown timers that render fresh content at the moment someone opens the email rather than when it was sent, and trigger order confirmation emails with complementary product recommendations.
Nosto
Nosto unifies your marketing and product data so you can personalise 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 behaviour, without needing 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 personalise on-site banners and recommendations.
- Trigger abandonment flows when someone searches but doesn't buy.
- Drop personalised product recommendation blocks straight into your emails.
Doofinder
Doofinder is an AI-powered search engine and discovery layer built into your website that returns text, image, or voice results quickly, helping customers find what they're looking for while they browse.
Klaviyo's Doofinder integration brings that search data into your CRM so you can re-engage shoppers who searched but didn't convert, build campaigns around what people are actually searching for by segmenting customers by interest or trending products, and track trending searches to spot patterns and adjust your messaging ahead of the competition.
Rebuy
Rebuy uses AI and machine learning to surface smart product recommendations across the shopping experience, driving up-sells and cross-sells at key moments like basket, check-out, and post-purchase.
Use Klaviyo's Rebuy integration to grow your subscriber list and boost conversions across the customer lifecycle by personalising on-site offers based on customer segments, capturing high-intent shoppers' phone numbers at the basket stage to grow your text message list while they're already engaged, recommending products in flows or account pages based on order-placed triggers, and featuring customer ratings and reviews inside personalised product recommendations.
Wunderkind
Wunderkind is an AI decisioning platform built around identity resolution. Its identity graph tracks more than 9 billion device profiles and over a billion unique user identities, using more than 2 trillion digital events a year to turn anonymous website traffic into known customers without relying on third-party cookies.
Wunderkind joined the Klaviyo App Marketplace in January 2026. The integration feeds Wunderkind's identity insights directly into your unified customer profile, so you can identify more visitors by recognising shoppers across sessions, devices, and brands, build real-time profiles, segments, and flows around visitors you couldn't previously identify, and drive incremental revenue through expanded audience reach, higher match rates, and better-timed triggered campaigns.
Contentsquare
Contentsquare is an experience analytics platform that shows you what shoppers actually do on your site: session replays, heatmaps, journey drop-off points, and frustration signals like rage clicks or dead clicks that a conversion report alone won't surface.
Its behavioural data can be connected to Klaviyo through workflow-automation platforms like Workato, pulling friction and engagement signals into the same customer profile you already use for segmentation. That makes it possible to flag high-friction pages and route affected visitors into a dedicated win-back or support-led flow, segment shoppers by on-site engagement depth rather than purchase history alone, and prioritise which parts of the site experience to fix first.
Algolia
Algolia powers fast, relevant on-site search and discovery, letting you personalise search results and category pages based on what shoppers search for, not just what they click on.
The Algolia and Klaviyo Connect integration is a bi-directional connection with a guided setup wizard. Once connected, you can send search behaviour, including queries, clicks, conversions, and null-result searches, into Klaviyo as trackable events on each customer's timeline alongside purchase history and email engagement, recover abandoned searches with targeted follow-up messages, bring Klaviyo segments into Algolia to personalise on-site search results by audience, and trigger campaigns from real buying intent rather than browsing or purchase behaviour alone.
Movable Ink
Movable Ink personalises the content inside an email or text message at the moment it's opened, rather than at the moment it's sent, using real-time data to change what someone sees.
Through Movable Ink's Universal Data Activation partnership with Klaviyo, you can feed real-time interaction data from Klaviyo flows into Movable Ink, which automatically maps it into personalised content with no manual data work required. That includes personalising email content at open time based on the latest customer data rather than a static snapshot from send time, personalising text message content the same way, with Klaviyo Text orchestrating the send while Movable Ink personalises what's inside it, and keeping content relevant across a campaign's full send window even as inventory, pricing, or customer behaviour shifts.
