Core News has quite a few subscribers via RSS and email, but a few months back Google terminated the Feedburner email service. We have now moved over to a Feedburner alternative called follow.it.
The new service offers way more subscribing alternatives like filtering on keywords and tags, and deliver updates to Telegram, Twitter, email, etc. See subscribing options on this site: https://follow.it/core-news?action=followPub&filter
For those subscribing via email there will be some visual changes as follow.it have a different layout compared to Feedburner and other time slots of sending out newsletters.
Hers is my affiliate link if anyone one to use it on their own website: https://follow.it/s/oIOS
Let us know if you are facing any issues with the new service.
