Klaviyo Connector

September 24, 2026
Whalesync changelog

The Klaviyo connector is live in beta. A Klaviyo account becomes a base with three tables, Profiles, Lists, and Segments, that you can sync with Airtable, Notion, Google Sheets, Supabase, HubSpot, or any other Whalesync connector.

Profiles sync both ways: the built-in fields, the address, the custom properties Whalesync finds on your profiles, and list membership, so adding a row to a list in Airtable adds that person to the list in Klaviyo. Lists can be created, renamed, and deleted. Segments, segment membership, email and SMS consent, and Klaviyo’s predictive analytics are read-only. Changes arrive by polling rather than webhooks. Whalesync never deletes a Klaviyo profile and never sends a message to one.

Sign in with Klaviyo or paste a private API key, and map. Read the Klaviyo connector docs.
