Why teams connect Customer.io and Full Enrich

Stop re-entering the same information in Customer.io and Full Enrich: 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 Events, Segments, Campaigns, Broadcasts in Customer.io with Enrichment requests, Contacts, Enrichment results, Emails in Full Enrich 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

  • Land delivery and engagement events (sent, opened, clicked, bounced) from reporting webhooks into a warehouse for attribution analysis.
  • Keep unsubscribe and subscription-preference state consistent between Customer.io and the CRM to avoid compliance gaps.
  • Enrich new CRM contacts with verified emails and mobile numbers as they are created.
  • Run waterfall enrichment over warehouse lead lists before importing them into outbound sequencers.

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

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