The Newsletter Pop-Up add-on displays a pop-up box asking people to sign-up to receive newsletters.
In previous versions of the Debutify Shopify theme, the language for the Newsletter Pop-Up add-on was changed in the theme settings. When updating your Shopify theme to Debutify 4.6.0, you will notice there are no text boxes or labels under theme settings (admin> customize> theme settings> newsletter pop-up).
Click here if you are using Debutify 4.5.0 or earlier.
