Stay updated with private channel messages in Slack by creating an RSS feed for them. With this workflow, when a new message is posted to a private channel in your Slack, an item will be added to your RSS feed in the RSS by Nekton app. It's an easy way to keep track of important updates and discussions from your private channels in one central location.
RSS (really simple syndication) is pretty much the industry standard for feed readers. You'll find RSS feeds in almost every app imaginable.
