You can control how many posts appear in your RSS bundle in two different ways, depending on what you want:
Option 1: Limit total number of posts (all feeds combined)
This controls the total number of posts your bundle will show, across all feeds.
1. Open your Bundle.
2. Click the Customize button under the Feed Output section.
3. Adjust the value of Number of posts.
4. Click Save.
Option 2: Limit Number of Posts Per Feed
This option controls how many posts are pulled from each individual feed in your bundle.
1. Open your Bundle.
2. Scroll to the Feeds section.
3. Toggle Limit posts per feed to ON.
4. Set the number of posts you want per feed (e.g. 5).
The "Limit posts per feed" option is only available for bundles with fewer than 100 feeds.
