You may need to remove the Newsletter Request as by default, if you have imported the demo content, it appears in all pages.
First, you need to know there is a MailChimp short-code that handles all the requests. The code is inside a PL | Multibox widget placed on the Footer Widget Area. You can change text or even remove the Newsletter.
Go to Dashboard > Appearance > Widgets and locate the Footer Widget Area 1-1
Remove the PL | Mutlibox or change it’s contents.
Note: you can place a newsletter field anywhere (page, post, widget) by inserting the MailChimp code provided by the plugin.
