Why teams connect Klaviyo and Salesforce
Sync what happens in Klaviyo with the customer records in Salesforce, 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 Metrics, Campaigns, Flows, Templates in Klaviyo to Tasks and Events, Products and Price Books, Custom Objects, Accounts in Salesforce with bi-directional, real-time sync. Activity and record changes in Klaviyo update the matching contact or account in Salesforce, and CRM data flows the other way wherever Klaviyo can store and use it.
Common use cases
- Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
- Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
- Trigger provisioning or billing changes in an operational database when an Opportunity moves to closed-won.
- Consolidate multiple Salesforce orgs into a single database for cross-org reporting after an acquisition.
Where Klaviyo supplies contact or company data
Enriched fields land directly on records in Salesforce, and refreshes keep them from going stale.
Where Klaviyo processes payments
Charges, refunds, and subscription changes appear on the account in Salesforce, so revenue context lives with the relationship.
Where Klaviyo can store CRM context: fields kept current
Owner, lifecycle stage, or account details from Salesforce sync into Klaviyo, so people working there have the context without switching tools.
What you can sync between Klaviyo and Salesforce
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 | Salesforce objects | |
|---|---|---|
| Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. | Tasks and Events Activity records; usually read-only in syncs to feed activity reporting. | |
| Lists Static audience memberships sync in from CRMs and forms for targeting. | Products and Price Books Catalog and pricing data; commonly mastered in an ERP and written into Salesforce. | |
| Segments Dynamic audiences are readable so other tools can mirror who qualifies. | Custom Objects Org-specific tables with the __c suffix; discoverable via describe metadata so field mappings can be generated. | |
| Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows. | Accounts Company records that anchor most syncs; typically mapped to customer tables in a database or ERP. | |
| Metrics Event type definitions organize the activity stream used in segmentation and attribution. | Contacts People linked to Accounts; synced two-way with marketing, support, and warehouse person records. | |
| Campaigns Email and SMS sends expose performance data for warehouse-based reporting. | Leads Unqualified prospects; often written into Salesforce from enrichment or product-signup pipelines. |

FAQ
Klaviyo and Salesforce integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Klaviyo and Salesforce: authenticate both systems, choose the objects to sync (such as Klaviyo's Profiles and Lists), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Common patterns for Klaviyo and Salesforce: Where Klaviyo supplies contact or company data; Where Klaviyo processes payments; Where Klaviyo can store CRM context: fields kept current. Enriched fields land directly on records in Salesforce, and refreshes keep them from going stale.
-
Klaviyo: REST API compliant with the JSON:API specification. Authentication: OAuth 2.0 for apps or private API keys. Salesforce: REST, SOAP, and Bulk APIs. Authentication: OAuth login via a Salesforce user (browser-based authorization flow); requires "API Enabled" permission for polling mode, plus "Author Apex" and "Customize Application" OR "Modify All Data" for trigger mode. Stacksync manages authentication, retries, and rate limits on both sides.
-
Klaviyo: Klaviyo's current APIs follow the JSON:API specification, so payloads use typed resource objects with relationships rather than flat JSON. Salesforce: Non-writable objects, non-triggerable objects (trigger mode), and tables without a last_modified_data column (polling mode) cannot be synced yet. Stacksync's field mapping accounts for these differences between Klaviyo and Salesforce without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Klaviyo and Salesforce records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Klaviyo and Salesforce connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Klaviyo–Salesforce integration in-house.
