People are not able to subscribe to my newsletter (Recapchat) - Brooklyn theme

I have several issues with my bottom page subscribing newsletter. Firstly, the Recapchat doesn't work even if you have a good answer. Also, people aren't receiving the 10% in the email confirmation. I know it could be a problem with Klaviyo since the two are linked, but I know that the subscribed newsletter on the bottom of my page is in the Brooklyn theme by default. 

My store is www.artifulboutique.com if you ever want to check and help me. Thanks!
