This n8n workflow automates the process of generating and sending a daily email digest of recent emails. It is designed to save time by summarizing important email content using AI, making it easier for professionals to stay updated without manually reading through all messages.

The workflow begins with a Schedule Trigger that activates every morning at 7 AM. It then constructs a Gmail search query to fetch emails received in the last 24 hours. The Gmail node retrieves all matching emails that are unread. These emails are passed to an Aggregate node to consolidate relevant data fields like sender, recipient, subject, snippet, and CC.

Next, the aggregated data is analyzed using an AI-powered language model (OpenRouter GPT-3.5-turbo) through a langchain node, which extracts key topics, action items, deadlines, and summarizes the content into a clear digest. This summary is then sent as an email to the user or specified recipient via the Gmail node.

A custom JavaScript node calculates the previous day’s date and constructs the search query dynamically, ensuring the workflow always processes the last 24 hours. Overall, this workflow is highly useful in scenarios where daily email triage, reporting, or task management is required, especially for busy professionals, managers, and team leads.

It integrates Gmail, AI language processing, and automation scheduling to streamline daily email monitoring and reporting, increasing productivity and ensuring critical information is promptly summarized and communicated.
