Klaviyo + Shopify: The Best Email Marketing Solution

1. What is Klaviyo?

Klaviyo is an email marketing and CRM platform that allows businesses to create targeted and automated email campaigns using their customer data. It offers features such as mailing list segmentation, flow creation (email flows), deep integration with online stores, and performance analysis tools to help brands maximize their conversions and sales. Klaviyo benefits from a global partnership with Shopify. The two solutions are very well integrated, making them a winning duo for many e-commerce stores.

In 2024/2025, Klaviyo is focusing on real-time personalization, synchronized audiences (paid & owned), generative AI (subjects, content, testing), and multi-channel attribution measurement — levers that increase ROI and marketing execution speed.

2. Klaviyo features include:

• The ability to segment mailing lists to target email marketing campaigns based on profile data and customer journeys;
• Customizable email templates to create aesthetic and reassuring designs;
• Flow creation and campaign automation to send relevant and timely messages;
• Integration with e-commerce platforms like Shopify to synchronize product and customer data;
• Performance analytics to measure campaign effectiveness and optimize results;
• Advanced email marketing features such as win-back campaigns, loyalty campaigns, referral campaigns, and retargeting campaigns;
• Integrations with other marketing tools such as social networks, other Shopify apps (JudgeMe, etc.), traffic tracking tools, and payment tools.

Note: Klaviyo also offers native signup & pop-ups (A/B testable), synchronized advertising audiences (Meta, Google, TikTok), SMS (opt-in, scenarios, opt-out), and APIs to ingest business events (post-purchase, loyalty, returns, etc.).

3. What is a flow in Klaviyo?

A flow in Klaviyo is a set of automated rules and actions that are triggered by specific events. Flows allow brands to set up automated email marketing campaigns that are triggered by specific customer actions, such as signing up for a mailing list, purchasing a product, abandoning a cart, etc.

Flows can also be used to create personalized email sequences based on customer interests and behaviors. For example, you can create a flow that sends a welcome email to a new customer, or a flow that sends a reminder email to a customer who has abandoned a shopping cart.

There are many types of flows available in Klaviyo, such as welcome flows, win-back flows, loyalty flows, referral flows, and retargeting flows. Each of these flows allows targeting customers and prospects at the best time to maximize conversions.

Best practices: dynamic time delays, clear entry/exit conditions, splits by customer lifetime value (CLV) and channel, and automatic suppression of inactive profiles according to GDPR criteria.

4. How does Klaviyo work?

Klaviyo works by allowing brands to connect their e-commerce platform (e.g., Shopify, Magento, BigCommerce, etc.) to their Klaviyo account. Klaviyo can then synchronize data from your e-commerce products, customers, and other applications (Referrals, reviews, returns, etc.) with its platform, allowing you to target your marketing campaigns in a highly sophisticated way.

Once the data is synchronized, you can use Klaviyo's mailing list segmentation features to create customer segments based on criteria such as purchase history, interests, profile information, Shopify tags, Shopify order statuses, etc.

You can then use these segments to target your automated email campaigns. Klaviyo also provides analytics tools to track the effectiveness of email campaigns, including open rates, click-through rates, conversions, and sales. Brands can then use this data to refine their strategy and optimize their campaigns.

Useful new levers: real-time profile enrichment via forms, predictive analytics (purchase propensity, estimated purchase date), multi-touch attribution, CDP connectors, and webhooks to synchronize your own events.

5. What are the benefits of Klaviyo?

The benefits of Klaviyo include:

6. What are the difficulties in using Klaviyo?

There are some potential hurdles to overcome when using Klaviyo, including:

• Cost: pricing depends on the base size (email/SMS). Clean regularly to remove inactive users and control costs.
• Learning curve: to exploit its full potential (triggers, conditions, web tracking), expect a learning period.
• Advanced integration: in multilingual/multi-store environments, the mapping of events and attributes requires precise framing.
• Basic hygiene: deliverability, opt-in, bounce management: to be handled continuously.
• Strategy: define objectives, segmentation, scoring, content, cadence — then iterate via tests.

7. The integration of Klaviyo and Shopify: a winning combo!

Klaviyo and Shopify are official partners, and their integration is very popular with Shopify users.

The integration of Klaviyo with Shopify is quite simple to set up and is one of the services offered by Stellar. Shopify offers a Klaviyo app in the App Store, which can be installed directly into your online store. Once installed, the app will automatically synchronize product and customer data from your online store with your Klaviyo account, allowing email campaigns to be targeted based on this data.

It is also possible to manually connect your Klaviyo account to your online store using Shopify's integration settings. This allows synchronization of customer and order data from your online store with Klaviyo.

There are also integrations with other Shopify features, such as payment settings, order confirmation pages, thank you pages for subscriptions, subscription confirmation pages, unsubscribe pages, welcome pages for subscriptions, etc.

In summary, the integration of Klaviyo with Shopify is seamless and allows you to synchronize your product catalog, customer base, and e-commerce orders with your Klaviyo account to improve your email marketing strategy precisely and effectively for a "seamless" user experience and a better conversion rate.

8. How much does Klaviyo cost?

Klaviyo offers a pricing model based on the number of contacts in your mailing list. Prices start at $0 per month for a maximum of 250 contacts, and increase depending on the number of contacts. There are also higher plans for businesses with more advanced needs. Here is Klaviyo's official pricing table.

It is also important to note that some Klaviyo fees depend on the integrations and tools used. For example, integrations with e-commerce platforms or certain traffic tracking tools may incur additional costs.

It is important to note that Klaviyo offers a 14-day free trial period to allow you to test the platform in real time before committing to a long-term paid subscription. It is therefore important to understand the features and associated costs before committing and migrating your email base from another solution.

9. Between Klaviyo and Mailchimp: which solution to choose for your Shopify store?

There are many email marketing tools available on the market, but Klaviyo and Mailchimp are considered the two main choices for Shopify users. Here are some factors to consider to help you decide which one is best suited for your store:

• Segmentation: Klaviyo excels in behavioral & e-commerce segmentation (Shopify events). Mailchimp is simpler but less granular.
• Automation: rich scenarios and multiple triggers on Klaviyo; more basic workflows on Mailchimp.
• Analytics & attribution: Klaviyo offers revenue-oriented reports, cohorts, CLV; Mailchimp's analysis is more generic.
• Cost: Mailchimp may seem cheaper, but Klaviyo's revenue lift often compensates. Optimizing basic hygiene is key to controlling the bill.
