Two-way sync
Changes in Klaviyo or Nimble instantly reflect in both systems. No stale data, no manual imports.
Keep Klaviyo and Nimble in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Klaviyo holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.
Stacksync connects Flows, Templates, Catalog Items, Tags in Klaviyo to Companies, Deals, Tasks, Activities in Nimble with bi-directional, real-time sync. Activity and record changes in Klaviyo update the matching contact or account in Nimble, and CRM data flows the other way wherever Klaviyo can store and use it.
Prospects, sends, and replies sync into Nimble, keeping lead status current without manual imports.
Enriched fields land directly on records in Nimble, and refreshes keep them from going stale.
Charges, refunds, and subscription changes appear on the account in Nimble, so revenue context lives with the relationship.
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 | Nimble objects | |
|---|---|---|
| Metrics Event type definitions organize the activity stream used in segmentation and attribution. | Deals Pipeline records linked to contacts, synced to keep revenue systems aligned with sales activity | |
| Campaigns Email and SMS sends expose performance data for warehouse-based reporting. | Tasks To-do items tied to contacts, mirrored into work-management tools or reporting tables | |
| Flows Automation definitions and their engagement data sync outward for attribution. | Activities Calls, events, and interaction history used for engagement reporting outside Nimble | |
| Templates Message templates are accessible via API for content management workflows. | Notes Free-text records attached to contacts, replicated for a complete account timeline | |
| Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. | Tags Segmentation labels that map to list membership or filters in downstream systems | |
| Tags Organizational labels on campaigns, flows, and lists support reporting rollups. | Custom fields Account-defined contact attributes that carry enrichment or internal identifiers |

Yes. Stacksync provides a managed, real-time two-way integration between Klaviyo and Nimble: authenticate both systems, choose the objects to sync (such as Klaviyo's Metrics and Campaigns), map fields visually, and changes propagate both ways in milliseconds — no code required.
Change detection on Klaviyo: Polling on updated timestamps; outbound webhooks exist for event topics (availability depends on plan or app-partner status) and as flow webhook actions. On Nimble: Polling on record modification timestamps. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
On the Klaviyo side: Flows, Templates, Catalog Items, Tags, plus custom fields where Klaviyo exposes them. On the Nimble side: Companies, Deals, Tasks, Activities. Stacksync auto-detects both schemas and converts types between the two systems.
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
