Automatically Label Gmail Messages with AI

Overview

This n8n workflow is designed to automate the labeling of your Gmail messages. It begins by triggering on new incoming emails via the Gmail trigger node. Then, it fetches the full message content using the Get message content node. The core logic resides in the Assign labels for message node, which utilizes an AI (specifically, an OpenAI Chat model) to analyze the email's text and determine appropriate labels based on a pre-defined prompt. The AI's output is parsed by the JSON Parser node to extract the suggested labels. Subsequently, the Get all labels node retrieves existing labels from your Gmail account, and the Split out assigned labels and Merge corresponding labels nodes process these alongside the AI-generated labels. Finally, the Aggregate label IDs and Add labels to message nodes are used to add the determined labels to the original email. This workflow solves the problem of manually sorting and categorizing emails, saving time and improving organization by intelligently assigning labels.
