Klaviyo (Actions) Destination

Klaviyo is a powerful email platform focused on ecommerce that helps companies make more money. It supports segmentation based on category and event triggers like product bought, page viewed, email engagement, or amount spent.

It measures opens, clicks, revenue generated, breakdown of generated revenue based on custom attributes (like campaign type or amount gained per recipient), and provides trend reports, cohort analysis, and subscriber growth.

Klaviyo lets you send personalized newsletters, automates triggered emails, product recommendations, welcome campaigns, order announcements, push notifications, and syncs your data to Facebook custom audiences.

FAQ

Dealing with Error Responses from Klaviyo’s API

429 Too Many Requests

If you’re encountering rate limiting issues, consider enabling batching for the Action receiving these errors. To enable batching, navigate to the mapping configuration and set “Batch data to Klaviyo” to “Yes”. This adjustment might help alleviate the rate limiting problem.

409 Conflict

In most cases, you can safely ignore a 409 error code.

When you use the Upsert Profile mapping to send Identify events, Segment first attempts to create a new profile in Klaviyo. If the first request returns with a 409 error code, Segment sends a second request to update the existing profile with the given profile ID.

403 Forbidden

Some customers experience 403 errors when sending audience data to Klaviyo through Segment. This occurs due to Klaviyo’s security measures blocking requests from shared IPs, which are common when using cloud-hosted platforms, like Segment, that use dynamically generated IP addresses.

To reduce the number of 403 errors that you encounter, enable IP Allowlisting for your workspace. For more information the range of IP addresses Klaviyo uses for integration traffic, see Klaviyo’s How to allowlist Klaviyo integration traffic IP addresses documentation.

Can I send Engage Audiences to a pre-created Klaviyo List?

No. Engage audiences are designed to initiate the creation of new lists in Klaviyo when you use the “Add Profile to List - Engage” mapping. You cannot link Engage lists to existing Klaviyo lists and cannot edit the List ID for Engage audiences.

How can I unsuppress a profile when adding it to a list?

When adding a user to a list, our action make use of the Bulk Profile Import endpoint (when batching is enabled), and the Add Profile To List endpoint for non-batched requests. Both of which will not update a users suppression status if they were previously suppressed.

To ensure a suppressed profile gets unsuppressed, you can use the “Subscribe Profile” action. When a profile is subscribed in Klaviyo, it automatically unsuppresses any previously suppressed user. You can combine this action with other actions to achieve your goal. If this solution does not fully address your use case, please contact us at friends@segment.com so we can consider your specific requirements.

Engage

You can send computed traits and audiences generated using Engage to this destination as a user property. To learn more about Engage, schedule a demo.

For user-property destinations, an identify call is sent to the destination for each user being added and removed. The property name is the snake_cased version of the audience name, with a true/false value to indicate membership. For example, when a user first completes an order in the last 30 days, Engage sends an Identify call with the property order_completed_last_30days: true. When the user no longer satisfies this condition (for example, it’s been more than 30 days since their last order), Engage sets that value to false.

When you first create an audience, Engage sends an Identify call for every user in that audience. Later audience syncs only send updates for users whose membership has changed since the last sync.

Settings

Segment lets you change these destination settings from the Segment app without having to touch any code.
