Hello, I need some big help in fixing or better understanding how my email subscriptions work. I see that I have two different locations to add your email. A pop up and down below in the footer. When I try to type my email into the footer I get "404: page not found" and also "That's odd. This page appears to be missing". How can I fix this problem? Also with the pop up, how can I make it were a automatic discount code is sent to the subscriber? Thank you.
