It's easy to shape a single mailing campaign using audience filtering. You can use that some functionality for your RSS-based campaigns, too.
All you need is an RSS-based campaign and a group. Perhaps you want to send more focused emails to a subset of your audience.
Start at your list's dashboard.
Click Settings > Edit Campaign
On the next screen, click Edit Audience.
On the next screen click Choose Group Filters
When that expands, choose the group you want to use to shape your RSS-based mailing. Then click Next Step: Settings
To apply your changes, on the next screen you must click Finish: Save This Campaign
Shaping your RSS-based campaigns audience is a feature only available to FeedBlitz Accel and Enterprise Clients.
