Hi there @cafeleathersupply
Thanks for your follow-up and clarification. Unfortunately it would not be possible to link different Woocommerce language forms to different lists; It's because that accepts marketing only allows customers to be added to one list. However, if you want to allow customers to choose which list they are added to, the following Community post outlines how to take advantage of multiple buttons within a signup form.
Alternatively, another solution would be creating a signup form with a multi-checkbox field asking what sort of information your subscribers would like to receive. Each of these options in the multi-checkbox can then be used to tag your subscribers with a specific profile property. You can then use segmentation to capture these customers who are on this particular list your signup form is submitting to and have this specific profile property. So you could have one for EN preference and ES.
The best alternative I would suggest would be to either use different Klaviyo accounts for your different language sites or somehow segmenting the users out from one main list into the EN and ES segments. The second one would require some manual work as you would have to export CSV files and edit them and reimport them. A related article can be found:
Hope this helped clear things up!
