Klaviyo / Omnisend Email & SMS Sync

Key Features

Real-time event streaming via Magento observers and plugins: product viewed, added-to-cart, started checkout, and order placed pushed to Klaviyo Track or Omnisend Events API

Full catalog feed sync (SKU, price, stock, images, URLs, EAV custom attributes) refreshed via cron and on catalog_product_save_after

Customer, subscriber, and list/segment sync with newsletter consent state preserved across Magento and the messaging platform

Abandoned-cart and browse-abandonment events captured from quote and product-view activity to feed your recovery flows

Back-in-stock event hooks fired when inventory crosses the salable threshold to trigger 'now available' automations

Choice of provider at build time: Klaviyo or Omnisend, wired to the correct REST endpoints and auth scheme

Cron-backed retry queue so transient API failures are re-attempted rather than silently dropped

Multi-store-view aware: per-website API keys, store-scoped catalog feeds, and locale-correct payloads

Admin configuration panel gated by Magento ACL, with masked API keys and an on-demand connection test

Webhook/API-key health logging and a status surface so retention ops can confirm events are flowing

Built with dependency injection (di.xml), service contracts, and PSR-12 code that survives Magento upgrades

Compatible with Magento Open Source and Adobe Commerce 2.4.x, frontend / adminhtml / crontab areas

About this Product

Retention teams live in Klaviyo or Omnisend, but those platforms are only as smart as the Magento data they receive. The off-the-shelf connectors often miss custom attributes, multi-store views, or the exact event timing your flows depend on. This extension is custom-built by ECOSIRE to push deep, reliable Magento 2 data into whichever platform you've standardized on.

We ship a dedicated module under app/code/Ecosire/KlaviyoOmnisendSync that hooks Magento's native event/observer system and plugins (interceptors) to capture behavior in real time: checkout_cart_product_add_after, catalog_controller_product_view, sales_order_place_after, and customer/subscriber lifecycle events. Each event is normalized through a service contract and pushed to the Klaviyo Track/Identify API or the Omnisend Events API, with a cron-backed retry queue so a transient API outage never drops a signal.

Your product catalog is synced as a structured feed — name, SKU, price, stock status, images, URLs, and the EAV custom attributes your flows segment on — refreshed via cron and on catalog_product_save_after. Customer and subscriber data flow to the right lists/segments with consent state intact, and back-in-stock hooks fire as inventory crosses zero so your "now available" automations trigger themselves.

Everything respects multi-store views, admin ACL for the configuration panel, and Magento's areas (frontend, adminhtml, crontab). It runs on Magento Open Source and Adobe Commerce 2.4.x. Because it's build-to-order, we scope it to your data model, install it on your environment, run a verified end-to-end test against your real Klaviyo/Omnisend account, and support it afterward. This is not an instant Adobe Commerce Marketplace download — it is engineered for your store and delivered with a clear lead time.

Who this is for

DTC Retention Marketer

Owns the Klaviyo/Omnisend account and needs Magento behavioral and catalog data flowing reliably so abandoned-cart, browse, and back-in-stock flows actually fire on accurate signals.

Magento Store Owner / Ecommerce Manager

Has standardized retention on one platform and wants a connector that respects custom attributes and multi-store views without an in-house developer maintaining it.

Agency or In-House Magento Developer

Wants a clean, DI-based, upgrade-safe module that uses native events and service contracts instead of a black-box extension, and a vendor who will support it.

Frequently Asked Questions about Klaviyo / Omnisend Email & SMS Sync

How long until it's delivered and live on my store?

Because this is build-to-order, typical delivery is around 5 to 10 business days after we confirm scope, your Magento version, and which platform (Klaviyo or Omnisend) you use. We build and test on a staging copy first, then install on production. Heavier customization (many custom attributes, complex multi-store mappings) can extend the timeline, and we give you a firm estimate before any work begins.

Do you provide ongoing support and updates after delivery?

Yes. Every build includes a post-delivery support window to resolve any issue with the events, catalog feed, or platform configuration. Because Klaviyo's and Omnisend's APIs and Magento's 2.4.x releases evolve, we also offer ongoing maintenance to keep the integration compatible. Support and update terms are agreed up front so there are no surprises.

Is this an Adobe Commerce Marketplace extension I can download instantly?

No. This is a custom extension that ECOSIRE builds, installs, and supports on your specific Magento install. There is no instant Marketplace download. That trade-off is deliberate: we tailor the events and catalog feed to your exact data model and verify it end-to-end against your real Klaviyo or Omnisend account before sign-off.

Will it work with my custom product attributes and multiple store views?

Yes. We map the EAV custom attributes your flows segment on into the catalog feed, and the module is multi-store-view aware — per-website API keys, store-scoped feeds, and locale-correct payloads. We confirm exactly which attributes and store views to include during scoping.

Does it run on both Magento Open Source and Adobe Commerce?

Yes, on Magento Open Source and Adobe Commerce 2.4.x. The module uses native Magento patterns — observers, plugins (interceptors), service contracts, di.xml, and cron — so it installs cleanly on either edition and is built to survive standard Magento upgrades. We confirm your exact patch version during scoping.
