If you want to create a Email subscription using google Feedburner, we will need to have rss.xml which can be added as feed, below is an example of simple xml file which we can upload to website and give as input to feedburner.
<?xml version="1.0" encoding="UTF-8" ?>
<rss version="2.0">
<channel>
<title>Website Title</title>
<link>https://www.mywebsite.com</link>
<description>My Website Description</description>
<item>
<title>Home Page</title>
<link>https://mywebsite.com/index.html</link>
