This actor enables you to monitor content on any web page and sends an email notification with before and after screenshots whenever any content changes. You can use this to create your own watchdog for prices, product updates, sales, competitors, or any content that you want to keep an eye on.
Technically, it extracts text by selector and compares it with the previous run. If there is any change, it runs another actor to send an email notification, save, and send screenshots.

The actor needs a URL, content selector, and email address. A screenshot selector can also be defined or, if not defined, the content selector is used for the screenshot.
|url||String||URL to check||https://www.kickstarter.com/projects/solgaarddesign/carry-on-closet-solgaard-suitcase-shelf-and-usb||yes|
|contentSelector||String||Monitored area selector||.mb2-lg .flex||yes|

|sendNotificationText||String||Notification Text||Follow instructions in company wiki for updating the database||no|
|navigationTimeout||Number||Navigation Timeout in milliseconds||30000||no|
