<h4>Notify every WordPress post change!</h4>
You want to be notified when one of your contributors have submitted a new post for revision or an editor published one? Vice versa you want to notify your contributors when their posts got published? 
This is just the beginning of what you can achieve with Post Status Notifier (PSN)!
It works with all kind of custom post types, supports all custom taxonomies like categories and tags other plugins are using. You can grab all these taxonomy values and custom fields attached to a post and use them as placeholders in your custom notification texts. PSN has a powerful conditional template syntax featuring many filters and functions to get the most out of the placeholders!
Define as many notification rules as you need with all kind of settings, like custom CC, BCC and FROM emails addresses. PSN is extensible! Build your custom module to implement a new notification service.
PSN works great with plugins like WP Job Manager (<a href="https://www.ifeelweb.de/2014/666/notify-wp-job-manager-listings-wordpress-plugin-post-status-notifier/" rel="nofollow ugc">read more</a>), Calendarize.it (<a href="https://www.ifeelweb.de/2014/748/notify-calendarize-events-wordpress-plugin-post-status-notifier/" rel="nofollow ugc">read more</a>), Crowdfunding by Astoundify (<a href="https://www.ifeelweb.de/2014/706/notify-payments-crowdfunding-astoundify-post-status-notifier/" rel="nofollow ugc">read more</a>) or Advanced Custom Fields, just to name a few.
