Why teams connect Full Enrich and Klaviyo

Stop re-entering the same information in Full Enrich and Klaviyo: Stacksync keeps the records they share consistent in real time, in both directions.

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 Phone numbers, Credits, Enrichment requests, Contacts in Full Enrich with Events, Metrics, Campaigns, Flows in Klaviyo 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

  • Run waterfall enrichment over warehouse lead lists before importing them into outbound sequencers.
  • Backfill missing phone numbers on aging CRM records on a schedule.
  • Push offline, ERP, or subscription order events into Klaviyo as metrics to trigger post-purchase and win-back flows
  • Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data

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 Klaviyo is where the team documents or plans: keep its data fed

Information that originates in Full Enrich stays current in Klaviyo instead of going stale after a one-time paste.

What you can sync between Full Enrich and Klaviyo

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.

Full Enrich objects Klaviyo objects
Enrichment requests Submitted batches of contacts to enrich; processed asynchronously by the waterfall. Tags Organizational labels on campaigns, flows, and lists support reporting rollups.
Contacts The person inputs (name plus company or domain) sent for enrichment. Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes.
Enrichment results Completed records fetched by request ID or delivered via webhook. Lists Static audience memberships sync in from CRMs and forms for targeting.
Emails Returned addresses with verification status, written back to the CRM or database. Segments Dynamic audiences are readable so other tools can mirror who qualifies.
Phone numbers Returned mobile and direct-dial numbers from the provider waterfall. Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows.
Credits Account balance consumed on successful finds; monitored to pace sync jobs. Metrics Event type definitions organize the activity stream used in segmentation and attribution.
