WPML

The premium version of the “YITH WooCommerce Recvover Abandoned Cart” plugin gives you the compatibility with the multi-language sites that use WPML. The abandoned cart report tracks the language of the user of that cart. Click on any abandoned cart of your shop to know the related languages.

Just like any other WordPress post, the created email template can be translated with WPML in any language configured in the site.
Open the email template and activate the option you find at the bottom of the page, within the “Multilungual Setup” section.
Now you have to create the translated copy of the template with WPML through the related box in the right part of the page.

Once you will have ended the translation of all created templates, the plugin will send the emails in the related languages of the abandoned carts.
