Key features & capabilities
Our enhanced Klaviyo integration enables you to create seamless cross-channel marketing experiences.
Here's what you can now accomplish:
Sync customer data between platforms in real time
Collect valuable information from your WhatsApp conversations, such as product preferences and customer feedback, and automatically sync this zero-party data with Klaviyo to enrich your customer profiles.
This real-time syncing ensures that your customer data is always up-to-date, allowing for more timely and relevant communications. For example, collect product preferences through a WhatsApp conversation and use that information to personalize your next email campaign.
Leverage WhatsApp engagement data in Klaviyo
Leverage WhatsApp engagement data for more targeted campaigns. Our integration allows you to use WhatsApp-specific metrics like message open rates and click-through rates to create highly targeted segments in Klaviyo.
This enhanced segmentation capability enables you to tailor your messaging based on how customers interact with your WhatsApp communications.
Trigger charles flows from Klaviyo
Trigger WhatsApp flows directly from Klaviyo events for use cases like abandoned carts, back-in-stock notifications, and more.
The new direct metrics trigger allows you to initiate charles flows based on Klaviyo metrics without additional configuration in Klaviyo itself, streamlining your cross-platform automation.
This streamlined automation ensures that you're reaching customers at the right time, on the right channel. For instance, send an immediate WhatsApp message for a time-sensitive offer, followed by an email reminder if the customer hasn't responded.
Import Klaviyo audiences into charles
You can also import your pre-existing lists and segments from Klaviyo directly into charles for targeted WhatsApp broadcast campaigns, ensuring consistent audience targeting across channels.
Real world impact

Another client, Wellnest, significantly boosted their occupancy rates by leveraging personalized WhatsApp communications triggered by Klaviyo events.
