Alerts for new RSS feed content

How can I setup notifications on DTP, so that anytime I get new content for an RSS feed I am alerted?

You could set up a smart rule like this…

However, note you will not get notifications from Notification Center when you’re in DEVONthink, but you can choose other options.

Where does the “group name” variable come from?

When editing the smart rule right click and from the context menu choose *Insert Placeholder".
