What data syncs between HubSpot and Klaviyo
HubSpot is the source of truth for contacts in this integration: every contact, lifecycle stage, and deal event flows into Klaviyo, and Klaviyo email and SMS engagement is written back onto the HubSpot timeline.
| Data | Direction | Details |
|---|---|---|
| Contacts | HubSpot → Klaviyo | Every HubSpot contact with an email becomes a Klaviyo profile; Klaviyo never creates new contacts back in HubSpot. |
| Lifecycle stage and deal events | HubSpot → Klaviyo | Lifecycle stage changes, deal creation, deal stage changes, and closed-won arrive in Klaviyo in real time as flow-triggering events. |
| Email and SMS engagement | Klaviyo → HubSpot | Opens, clicks, sends, and unsubscribes are written to the HubSpot contact timeline with last-engagement properties. |
| Consent state | Two-way | Each system's consent state is mirrored onto the other as a visible property only; native subscription status is never changed or enforced across systems. |
| Custom properties | Two-way | HubSpot contact properties can map to Klaviyo profile properties and vice versa, configured per account. |
How teams use the HubSpot integration
Trigger flows from deal stage changes
Fire a Klaviyo flow when a deal moves to closed-won in HubSpot, sending onboarding or upsell email tied to the deal outcome.
See email engagement without leaving HubSpot
Sales and CS teams check the HubSpot contact timeline to see recent Klaviyo opens and clicks before a call, no need to check Klaviyo directly.
Segment by lifecycle stage in Klaviyo
Build a Klaviyo segment of contacts in the marketing-qualified-lead stage to run a nurture campaign that hands off cleanly once they become sales-qualified.
