If your business wants to create a blog or news feed that users can subscribe to via email, this is the best way to do it.
You’ll need the following:
1. A WordPress Website
2. A Ton of Content (blogs/news articles)
3. A Mailchimp account
Many WordPress RSS plug-ins aren’t supported anymore, but all WordPress sites have an automatic built in RSS feed at domainname.com/feed
Mailchimp has a special RSS to Email feature you can use to send updates to your lists automatically on your schedule after you make new posts to your WordPress site.
