Why teams connect Klaviyo and Lusha
Flow Lusha data into Klaviyo in real time — no exports, no schedulers, no custom scripts.
Lusha is a read-only source: Stacksync reads its data in real time and delivers it into Klaviyo, so Klaviyo always reflects the current state of Lusha — without exports, scripts, or schedulers.
Two tools in the daily stack often hold overlapping information: the same people, the same companies, or the same pieces of work, described twice. The tools do different jobs, so consolidating is not the answer; the overlap just needs to stop drifting.
Stacksync syncs Metrics, Campaigns, Flows, Templates in Klaviyo with Company Profiles, Email Addresses, Phone Numbers, Prospecting Results in Lusha in real time. You choose which records overlap, map the fields that should match, and pick a direction or let changes flow both ways. From then on, an update made in either tool is reflected in the other within seconds, without exports or copy-paste.
Because the sync is field-level, each tool keeps its own extras; only the shared data is held in agreement.
Common use cases
- Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
- Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
- Build prospecting lists from Lusha search results and sync them into the CRM as leads.
- Re-verify stale contact data on a schedule and flag records that no longer resolve.
Where both tools track people or companies: one consistent record
Contact and company details corrected in either tool update the other, so nobody works from the old version.
Where one tool produces events: mirror them in the other
Payments, replies, messages, or tickets created in one tool can create or update matching records in the other, keeping context in one place.
Where Lusha is where the team documents or plans: keep its data fed
Information that originates in Klaviyo stays current in Lusha instead of going stale after a one-time paste.
What you can sync between Klaviyo and Lusha
Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.
| Klaviyo objects | Lusha objects | |
|---|---|---|
| Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. | Person Profiles Contact-level enrichment results (work emails, phone numbers, title, company) returned per lookup. | |
| Lists Static audience memberships sync in from CRMs and forms for targeting. | Company Profiles Firmographic records (industry, size, location) appended to account or company rows. | |
| Segments Dynamic audiences are readable so other tools can mirror who qualifies. | Email Addresses Work emails written into CRM contact fields during enrichment. | |
| Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows. | Phone Numbers Direct-dial and mobile numbers appended for outbound calling workflows. | |
| Metrics Event type definitions organize the activity stream used in segmentation and attribution. | Prospecting Results Search-based lists of people and companies matching filters, used to seed lead lists. | |
| Campaigns Email and SMS sends expose performance data for warehouse-based reporting. | Bulk Enrichment Requests Batch lookups that enrich multiple records per request, used to backfill large contact lists rather than one-off calls. |
