Woo Email Control is a powerful enhancement for the Woocommerce email system, offering users greater customization and control over their email communications. This free WordPress plugin allows for the addition of product images, easy selection of header images, and the ability to display product categories and SKUs for each line item. It requires Woocommerce version 2.5 or higher, with full functionality available from version 2.6 onward. Users can embed and attach images within emails, which helps reduce spam classification and broken image links.

The plugin also features a robust testing facility that allows users to preview emails in their browser or send them directly to their email address. This functionality utilizes real order data, providing a realistic view of how emails will appear to customers without needing to create test orders. Woo Email Control is compatible with both standard and custom email templates, provided the necessary hooks and filters are maintained.
