You need to configure the outgoign smtp mail server for Confluence first. If you did not configure the outgoing mail server, this app does not work. You can find the documenation how to configure the mail server here.
Installation & Licensing
Log in to your Confluence instance as an administrator.
Click the admin dropdown and choose Atlassian Marketplace. The 'Find new apps' screen will be displayed.

E-Mail Stylesheet is a feature that needs some CSS knowledge to use. Some content on the page needs to have a different style while sent as an email. We can define a custom style for them using this option.
Here are the steps to create a custom style:
Open the HTML inspector of the browser on the page
Inspect the content to apply style
Define a "CSS selector" for it (using id, class, attribute, or tag name).
Test this selector by adding it to the CSS section of the inspector
Add new CSS into the selector and check the result
copy the selector and CSS into the app configuration and save it
