So, when is it relevant to switch email marketing tools to Klaviyo? In this article, we analyze the main concrete cases that justify a migration. You will discover how Klaviyo helps you:
- Segment and personalize your campaigns at scale

- Integrate your tools (Shopify, CRM, advertising) for an omnichannel strategy
Each scenario is illustrated with real-world examples and testimonials from companies that have gained in productivity, customer engagement, and ROI thanks to Klaviyo.
Introduction: Why Migrate to Klaviyo?
Since 2023, Klaviyo has experienced rapid growth, particularly after its IPO and strengthened partnership with Shopify. The platform has established itself as a leading alternative to Mailchimp, Sendinblue/Brevo, or HubSpot, thanks to its ultra-fine segmentation and its marketing automation engine. According to a 2024 Forrester study, 76% of e-commerce brands using Klaviyo see an increase in their email conversion rate within the first six months.
I have observed this transformation firsthand with my clients: an SME in fashion doubled its click-through rate by personalizing its email sequences with Klaviyo. Their marketing became more fluid, more targeted, and above all, much more profitable.
Case Study 1: Improve Segmentation & Personalization
Most email marketing tools offer basic segmentation. Klaviyo goes much further by combining transactional, behavioral, and CRM data. This allows you to send the right message at the right time to each customer.
Concrete example: one of my clients previously sent the same newsletter to all their contacts. With Klaviyo, we created dynamic segments: new customers, VIPs, inactive buyers… Each audience received tailored emails. Result: +40% open rates and +25% conversions.
According to the Litmus Email Marketing Report 2024, advanced personalization can generate up to 122% additional ROI. Klaviyo makes this approach accessible even to small marketing teams.
Case Study 2: Automate Your Marketing Campaigns
Marketing automation is no longer a luxury: it's a necessity. Klaviyo excels in this area with its ready-to-use workflows (abandoned cart recovery, post-purchase, birthday, win-back, etc.).
A merchant I worked with used to spend an hour a day sending manual emails. After migrating to Klaviyo, everything was automated. His team saved time to focus on strategy… while seeing sales increase by 30% thanks to automated scenarios.
Case Study 3: Better Analyze Your Performance
"What gets measured gets improved." Klaviyo offers an unparalleled level of advanced reporting in email marketing. Opens, clicks, sales attribution, SMS impact… everything is centralized in a customizable dashboard.
In 2024, Klaviyo launched new multi-touch attribution reports, allowing you to compare the impact of emails versus social media or paid advertising. A real game-changer for understanding where to invest your marketing budget.
Case Study 4: Integrate Your Marketing Tools
One of Klaviyo's strengths is its native integration with Shopify, WooCommerce, BigCommerce, as well as hundreds of other tools (Facebook Ads, Google Ads, CRM, customer support tools, etc.). This interoperability allows for orchestrating coherent omnichannel campaigns.
Example: by connecting Klaviyo to Shopify, a client was able to synchronize their purchase data and launch targeted SMS sequences in addition to emails. Result: +18% average order value and strengthened customer loyalty.
Conclusion
Migrating to Klaviyo is not just a tool change: it's a paradigm shift in how you manage your email and SMS marketing. Fine segmentation, smart automation, advanced analytics, and powerful integrations make it an indispensable lever for any e-commerce brand in 2025.
If you're looking to increase conversions, retain customers, and save time, Klaviyo is likely the evolution your marketing needs.
