What does the "Apply to each" action do in the created cloud flow?

The "Apply to each" action is designed to loop through a collection of items, allowing you to perform a set of actions for each item in that collection. In the case of processing multiple attachments in a single email, this action can be particularly powerful. When you receive an email with various attachments, the "Apply to each" action allows the flow to take each attachment one at a time and execute specified processing steps, such as analyzing the content of each attachment, extracting data, or applying any other business logic.

By using this action, the cloud flow can handle each attachment independently while still maintaining the context of the email that contained them. This modular approach ensures that all attachments are processed efficiently without requiring multiple flows for each attachment, streamlining the overall workflow. This functionality aligns perfectly with processing multiple attachments from a single email context, enabling comprehensive automation in scenarios where batch processing is necessary.
