WPMonty

Get Notified helps users know when certain events happen on their site. For now, the plugin simply sends a notification via email or a message to a Slack channel when a post changes status (i.e. publish, pending, draft, trash) your site.
I hope that others help contribute to this project to expand it and grow the number of integrations and WordPress events.

Get Notified

Get Notified is a simple to use notification plugin that notifies you of certain WordPress events.
