Hello Lesley,

Thanks for reaching out and thank you for using Crio Pro WordPress theme!

The default footer layout can be easily changed using the Customizer by doing the following.

1. In the Dashboard navigate to Appearance → Customize
2. In the Customizer menu navigate to Design → Footer → Layout

I didn’t see a blog on your site, so I’m unsure how you are going to set up for your newsletter, but if you needed to set up a blog for your newsletter you can use that guide to assist with the setting up of your blog. If you go this route you can put your signup form in a block at the bottom of your blog.

If you are just looking for a basic signup form you can use any contact form to accomplish this.

Setting up weForms
Setting up Ninja Forms
Contact Form Information

There are many others if you search contact form in the WordPress repository you will find many others that can accomplish this.

Let me know if you need me to go into detail on anything I will gladly assist where I can.

Thanks
Elana D.
