This shared intelligence allows for more informed decision-making and a cohesive customer journey. Without a solid integration, you'd be forced to manually export and import CSV files, a process that is not only tedious but also prone to errors and delays, leading to outdated customer information and missed opportunities.
Syncing Data and Personalizing the Customer Journey
The core of a successful Klaviyo and HubSpot integration is the bidirectional synchronization of contact data. This means that when a contact is created or updated in HubSpot, that information is automatically pushed to Klaviyo. Conversely, behavioral data from Klaviyo—such as email opens, clicks, and purchase history—can be synced back into HubSpot. This real-time data exchange enables hyper-targeted and personalized marketing. For example, a lead who has just filled out a form in HubSpot can be immediately added to a Klaviyo welcome flow, or a customer who has purchased a specific product can be segmented for a targeted cross-sell campaign, with all of this activity being visible to the sales team in HubSpot.

Common Use Cases and Strategic Automation
The possibilities for automation and enhanced workflows are extensive once the integration is in place. You can trigger Klaviyo flows based on specific HubSpot events, such as a lead changing their lifecycle stage from Marketing Qualified Lead (MQL) to Sales Qualified Lead (SQL). This can initiate a new nurture sequence designed to warm them up for a sales conversation. Similarly, if a deal goes "cold" in HubSpot, you can trigger a reactivation campaign in Klaviyo to re-engage the contact with targeted offers or content. This not only keeps leads warm without manual effort from your sales team but also helps to revive conversations that might otherwise be lost.
Overcoming the Lack of a Native Integration
It's important to note that Klaviyo and HubSpot do not offer a native, out-of-the-box integration. This means you will need to utilize a third-party tool or a custom API integration to connect the two platforms. Popular third-party automation tools like Zapier, Outfunnel, or Skyvia are often used to create workflows that automate the data transfer. These tools allow you to configure specific triggers and actions, defining exactly how and when data should move between the two systems. While a custom API integration offers the most control and flexibility, it typically requires more development resources and technical expertise.
Best Practices for a Seamless Integration
To ensure a smooth and effective integration, there are several best practices to follow. First, clearly define your business goals and the specific data points you need to sync. This will help you choose the right integration tool and set up your workflows efficiently. Second, pay close attention to field mapping to ensure that data is transferred and stored correctly in both platforms. Be sure to establish a clear naming convention for your Klaviyo lists and segments that reflects the data source from HubSpot. Finally, and most importantly, regularly review and test your integration to ensure it is functioning as intended. As your business evolves, your workflows may need to be updated to reflect new processes or data fields.
The Bottom Line: A Powerful Combination
Ultimately, the integration of Klaviyo and HubSpot creates a powerful synergy that combines the strength of a robust CRM with a top-tier email marketing platform. By unifying your customer data and automating key workflows, you can deliver highly personalized experiences, improve marketing efficiency, and drive significant business growth. While the lack of a native integration may require an intermediary solution, the benefits of a well-executed connection far outweigh the initial setup effort. For any business serious about scaling its marketing and sales efforts, a Klaviyo and HubSpot integration is a strategic necessity.
