Why teams connect Klaviyo and SugarCRM

Sync what happens in Klaviyo with the customer records in SugarCRM, 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 Lists, Segments, Events, Metrics in Klaviyo to Tasks, Campaigns, Custom modules, Accounts in SugarCRM with bi-directional, real-time sync. Activity and record changes in Klaviyo update the matching contact or account in SugarCRM, and CRM data flows the other way wherever Klaviyo can store and use it.

Common use cases

  • 01 Sync customer profiles between Klaviyo and the CRM or warehouse so segments can use fields beyond storefront data
  • 02 Push offline, ERP, or subscription order events into Klaviyo as metrics to trigger post-purchase and win-back flows
  • 03 Replicate Sugar modules into Postgres so RevOps can query CRM data with SQL and drive internal tools
  • 04 Keep contacts and leads aligned with marketing automation for consistent segmentation

Common sync patterns

Where Klaviyo supplies contact or company data

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

Where Klaviyo processes payments

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

Where Klaviyo can store CRM context: fields kept current

Owner, lifecycle stage, or account details from SugarCRM sync into Klaviyo, so people working there have the context without switching tools.

What you can sync between Klaviyo and SugarCRM

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 SugarCRM objects How this pairing syncs
Campaigns Email and SMS sends expose performance data for warehouse-based reporting. Campaigns Marketing efforts tied back to leads and opportunities. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Lists Static audience memberships sync in from CRMs and forms for targeting. Leads Unqualified prospects that convert into contacts and opportunities. Lists is specific to Klaviyo and Leads to SugarCRM — each maps to any object or custom field on the other side.
Segments Dynamic audiences are readable so other tools can mirror who qualifies. Opportunities Deals with revenue line items, synced to forecasting and billing. Segments is specific to Klaviyo and Opportunities to SugarCRM — 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. Cases Support tickets kept aligned with help desk tools. Events is specific to Klaviyo and Cases to SugarCRM — 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. Calls and Meetings Activity records used for engagement reporting. Metrics is specific to Klaviyo and Calls and Meetings to SugarCRM — each maps to any object or custom field on the other side.
Flows Automation definitions and their engagement data sync outward for attribution. Tasks Follow-ups attached to records across modules. Flows is specific to Klaviyo and Tasks to SugarCRM — each maps to any object or custom field on the other side.

How changes propagate between Klaviyo and SugarCRM

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.

Rate-limit considerations

  • Klaviyo: Per-endpoint burst and steady rate limits apply.
  • SugarCRM: Limits depend on the hosting model; on-premise instances are constrained by server capacity rather than fixed quotas.
