Why teams connect Klaviyo and MariaDB

Mirror Klaviyo's data into MariaDB so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Klaviyo through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in MariaDB.

Stacksync mirrors Campaigns, Flows, Templates, Catalog Items from Klaviyo into Primary and Unique Keys, System-Versioned Tables, JSON Columns, Stored Procedures in MariaDB and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Klaviyo, so the tool and the database never disagree.

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
  • Two-way sync between a MariaDB application database and a CRM so both systems hold the same customer records
  • Replicate ERP or billing master data into MariaDB databases that power customer-facing applications

React to changes as they happen

Updates in Klaviyo arrive as row changes in MariaDB, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Klaviyo with a query

Records from Klaviyo are ordinary rows in MariaDB; join them, index them, and use them in application logic without touching the vendor API.

What you can sync between Klaviyo and MariaDB

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 MariaDB objects
Templates Message templates are accessible via API for content management workflows. Tables The primary sync target; rows map to records in connected systems.
Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. Views Read-side projections used as outbound sync sources.
Tags Organizational labels on campaigns, flows, and lists support reporting rollups. Columns Field-level mapping targets with engine-typed values.
Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. Primary and Unique Keys Match keys for idempotent upserts.
Lists Static audience memberships sync in from CRMs and forms for targeting. System-Versioned Tables Temporal tables that retain row history natively, useful for auditing synced changes.
Segments Dynamic audiences are readable so other tools can mirror who qualifies. JSON Columns Semi-structured payloads validated with JSON functions.
