Choosing the right tool is essential to optimise your email marketing strategy. Klaviyo and Splio are two well-known CRM platforms offering advanced tools for managing customer data, building personalised campaigns and automation. This article will help you identify their key differences and determine which one best meets your needs.

Whether you are looking for integration through a customer data platform (CDP), precise segment creation, or efficient management of email campaigns, SMS or push notifications. This analysis explores criteria such as automation, usability (drag & drop, API), the quality of the data used and conversion rates. By optimising your CRM and your data platform, you can improve the customer experience and maximise the impact of your marketing campaigns.

Comparing the main features

Automation and segmentation features

Klaviyo stands out for its advanced automation and segmentation features, particularly well suited to the needs of e-commerce businesses. Thanks to its ability to analyse detailed behavioural data (purchases, product page visits, cart abandonment, etc.), Klaviyo creates dynamic segments that update automatically.

These segments make it possible to target specific customers at the right moment with hyper-personalised messages. The platform also offers an intuitive drag & drop editor, simplifying the creation of automated marketing workflows. This system helps brands personalise their email and SMS campaigns according to the different stages of the customer journey (acquisition, retention, reactivation, etc.), thereby optimising conversions and customer engagement.

Splio, on the other hand, positions itself more as a multichannel CRM platform and focuses on fine-grained segmentation and automated marketing workflows, while integrating an omnichannel approach. Its Customer Data Platform (CDP) centralises all customer data, whether it comes from the web, physical points of sale or other channels, enabling in-depth personalisation of the customer relationship.

Splio is notable for its ability to connect various data sources via APIs, thereby enriching its segments and automations with additional information. The platform makes it easier to orchestrate campaigns across several channels (email, SMS, push notifications, social media, etc.), which delivers a smooth and consistent customer experience, regardless of the touchpoint.

So while Klaviyo stands out for its precision in real-time automation and segmentation for mainly e-commerce brands, Splio, with its robust CDP and multichannel approach, is better suited to broader CRM strategies that involve interaction across different channels and touchpoints.

Integration with e-commerce and CRM platforms

Klaviyo integrates easily with leading e-commerce platforms such as Shopify, WooCommerce and Magento, as well as with popular CRMs. This synchronisation simplifies the use of customer data and lets you create targeted marketing campaigns using the information in your database. The goal is to maximise conversion through optimal data management.

Splio also connects to a wide range of CRM systems and marketing tools. It positions itself as an integrated platform able to centralise customer data across different channels. Its features include advanced options for Google Ads and cross-channel marketing campaign workflows, ideal for an omnichannel strategy.

Accessibility and ease of use

Klaviyo is valued for its ease of use. Its drag & drop interface allows non-technical marketing teams to create complex campaigns and workflows without needing programming skills. The segmentation and automation tools are designed to be accessible and easy to get to grips with.

Splio, for its part, offers a more technical interface, suited to businesses with complex needs that are looking for a highly customisable solution. While it requires a larger initial investment to master fully, Splio offers advanced possibilities for managing customer data and building marketing automation workflows.

Support and available resources

Klaviyo offers responsive customer support and a comprehensive resource library, including tutorials, webinars and practical guides. These tools help users make the most of its marketing automation, CRM, CDP and email marketing features. In addition, the active user community is a valuable resource for getting advice and sharing best practices.

Splio provides specialised technical support and supports its clients with dedicated training. As a provider of global marketing solutions, Splio also offers strategic advice to maximise the use of its tools, particularly in creating segments, managing scenario-based campaigns and cross-channel marketing activation.

Pros and cons: Klaviyo vs Splio

Klaviyo advantages

Klaviyo stands out for its customer-data-centric approach, allowing extremely fine-grained segmentation and advanced automation of email and SMS campaigns. Thanks to its ability to build marketing workflows based on real-time behaviour, it offers a decisive advantage for optimising conversion rates.

Native integration with leading e-commerce platforms, such as Shopify, simplifies data synchronisation and makes it easy to create relevant campaigns without significant technical effort. In addition, its intuitive drag & drop interface and its rich resource support make the platform accessible even to marketing teams without deep technical skills. Finally, Klaviyo combines marketing automation, CRM and customer data management in a single solution, delivering a smooth and unified customer experience.

Klaviyo drawbacks

The main drawback of Klaviyo lies in its pricing, which can rise quickly depending on the number of active contacts and the combined use of the email and SMS channels. This can represent a significant budget for growing businesses. Furthermore, although relatively simple to use, its advanced features require a certain learning curve to fully tap into the platform's potential, particularly for very complex marketing workflows. Finally, Klaviyo is mainly geared towards e-commerce, which can limit its appeal for certain industries that need a more general-purpose or broadly multichannel CRM approach.

Splio advantages

Splio establishes itself as a very comprehensive marketing automation and CRM platform, ideal for organisations looking for an integrated solution with strong multichannel potential (email, SMS, push notifications). Its Customer Data Platform makes it possible to centralise and enrich customer data from multiple sources thanks to a powerful web API, thereby making it easier to create granular segments and personalised marketing workflows.

The tool is particularly well suited to omnichannel strategies and advanced marketing activation, integrating, for example, Google Ads and other marketing solutions for unified campaign management. Its ability to handle the complexity of customer journeys and to offer in-depth personalisation considerably strengthens the customer experience.

Splio drawbacks

On the other hand, Splio can seem more complex to get to grips with, particularly for small marketing teams or SMEs, due to an interface that is less intuitive than Klaviyo's. The initial setup and configuration often require more sustained technical support. In addition, the costs related to licensing and to integrating the various features can be high and difficult to scale.

Finally, while its functional richness is an asset, it can also seem oversized for simpler marketing needs, sometimes making the solution less agile for quick test campaigns or one-off uses.

However, the complexity of the platform may require technical support, which represents a constraint for small teams. Pricing is also mentioned as a potential obstacle.

On the other hand, businesses with complex CRM and customer data management needs particularly appreciate the power of Splio and the quality of its technical support.
