Why teams connect Klaviyo and Nimble

Sync what happens in Klaviyo with the customer records in Nimble, in real time and in both directions.

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.

Common use cases

  • 01 Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
  • 02 Sync catalog items from an ERP or PIM so product recommendations and back-in-stock flows use current data
  • 03 Feed Nimble activity and task data into reporting dashboards without manual CSV exports.
  • 04 Sync Nimble contacts and companies into Postgres so ops teams can query socially enriched profile data with SQL.

Common sync patterns

Where Klaviyo runs outreach

Prospects, sends, and replies sync into Nimble, keeping lead status current without manual imports.

Where Klaviyo supplies contact or company data

Enriched fields land directly on records in Nimble, and refreshes keep them from going stale.

Where Klaviyo processes payments

Charges, refunds, and subscription changes appear on the account in Nimble, so revenue context lives with the relationship.

What you can sync between Klaviyo and Nimble

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 How this pairing syncs
Tags Organizational labels on campaigns, flows, and lists support reporting rollups. Tags Segmentation labels that map to list membership or filters in downstream systems Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. Tasks To-do items tied to contacts, mirrored into work-management tools or reporting tables Profiles is specific to Klaviyo and Tasks to Nimble — each maps to any object or custom field on the other side.
Lists Static audience memberships sync in from CRMs and forms for targeting. Activities Calls, events, and interaction history used for engagement reporting outside Nimble Lists is specific to Klaviyo and Activities to Nimble — each maps to any object or custom field on the other side.
Segments Dynamic audiences are readable so other tools can mirror who qualifies. Notes Free-text records attached to contacts, replicated for a complete account timeline Segments is specific to Klaviyo and Notes to Nimble — each maps to any object or custom field on the other side.
Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows. Custom fields Account-defined contact attributes that carry enrichment or internal identifiers Events is specific to Klaviyo and Custom fields to Nimble — each maps to any object or custom field on the other side.
Metrics Event type definitions organize the activity stream used in segmentation and attribution. Contacts Person records with multi-value fields for email, phone, and social profiles; the primary sync entity Metrics is specific to Klaviyo and Contacts to Nimble — each maps to any object or custom field on the other side.

How changes propagate between Klaviyo and Nimble

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Klaviyo Nimble Sub-second propagation

DetectionKlaviyo notifies Stacksync of record changes through webhook events. Polling on updated timestamps.

DeliveryEach detected change is written to Nimble through its API, with automatic retries and rate-limit backoff.

Nimble Klaviyo Interval-based propagation

DetectionStacksync polls Nimble for changes on an incremental schedule, reading only records changed since the previous pass. Polling on record modification timestamps.

DeliveryEach detected change is written to Klaviyo through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Klaviyo: Per-endpoint burst and steady rate limits apply.
  • Nimble: Subject to per-account API request quotas.
