Release Notes for Klaviyo's WooCommerce Extension

Last updated at:


Customers who integrate with WooCommerce also install the Klaviyo WooCommerce extension/plugin which allows you to add a newsletter signup form to your website, enable website activity tracking, and get data about when people start checkouts and view products so you can send out abandoned cart emails.

Install Plugin Updates

Plugin updates can now be installed directly from your WordPress Admin page. When an update is available, you'll see an alert next to your Plugins tab.  Click on your Plugins tab, scroll down to find the Klaviyo plugin, and install the update. 
If you prefer, you can still download the Klaviyo WooCommerce plugin manually from the Wordpress store.
