Understanding Klaviyo's Key Events

Events are the foundation of Klaviyo's power. These are actions that customers take on your store, and they trigger automations and enable sophisticated segmentation. Here are the essential Shopify events that Klaviyo tracks:

Core Ecommerce Events

Placed Order Triggered when a customer completes a purchase. This event includes:

• Order value and items purchased
• Shipping and billing addresses
• Discount codes used
• Customer lifetime value updates

Use cases: Post-purchase flows, cross-sell sequences, review requests, loyalty programme updates.

Ordered Product A separate event for each individual product in an order. This granular data enables:

• Product-specific follow-ups
• Related product recommendations
• Category-based segmentation

Fulfilled Order Triggered when an order ships. Includes tracking information when available.

Use cases: Shipping notifications, delivery follow-ups, "How's your order?" sequences.

Cancelled Order Fires when an order is cancelled, enabling win-back attempts.

Refunded Order Tracks full or partial refunds for customer service follow-up.

Browsing Behaviour Events

Viewed Product Captures when someone views a product page. This event is crucial for:

• Browse abandonment flows
• Retargeting based on interests
• Understanding product popularity

Added to Cart Triggered when items are added to the shopping cart. Combined with checkout data, this powers cart abandonment sequences.

Started Checkout Fires when a customer begins the checkout process but hasn't completed it.

Always test one variable at a time and ensure statistical significance.
