How to use pop up on Spanish Language pages

Hello support team,

I manage a bilingual website. We are using PopUp Pro to help sign up subscribers for our MailChimp newsletter list. The challenge is that we need to popup two different sign up forms based on the language of the page. We have two different lists in MailChimp, one for English language visitors and the other Spanish language visitors. How can I do this?

Thanks in advance for your help,
