Every result (item/record) from a search/list module will output a bundle. To “combine” them into a single structure, you’ll need to use an aggregator of some sort.
Aggregators are modules that accumulate multiple bundles into one single bundle. An example of a commonly-used aggregator module is the Array aggregator module. The next popular aggregator is the Text Aggregator which is very flexible and has applies to many use-cases.
There are other types of aggregator modules, click the below links to find out more:
- Array aggregator

Simply put an aggregator just before your Gmail module, and set the “Source Module” to your Facebook List module.
