Summarize Emails with AI and Send to LINE Messenger

Automate your inbox by summarizing emails with AI (Llama 3) and sending key takeaways, deadlines, and action items directly to LINE Messenger using n8n.

Overview

Automatically summarizes incoming emails using AI to extract important deadlines and action items, and sends the concise summary to LINE Messenger for quick review.

🧠 Description & Use Case

This workflow acts as a personal assistant for your inbox. It automatically reads emails from your account, uses a powerful AI model (Llama 3) to create intelligent summaries, and sends these summaries directly to you via LINE Messenger. It's designed to help you quickly identify important information, action items, and deadlines without having to manually sift through every email, saving you time and reducing inbox clutter.

🔄 How It Works:

  1. Read Emails (IMAP): The workflow begins by connecting to your email server using the Read emails (IMAP) node to fetch unread emails.

  2. AI Summarization: The content of each email (sender, subject, and body) is sent to an AI model via the OpenRouter API using an HTTPRequest node. The prompt instructs the AI to:

    • Create a concise summary.
    • Identify and highlight important emails with an emoji (🚨).
    • Extract and bold any deadlines or required actions, such as payment due dates or sign-up links.
    • Keep summaries for unimportant emails very short (under 10 words).
  3. Send to LINE Messenger: The final, formatted summary from the AI is sent as a push notification to your specified LINE user ID using another HTTPRequest node that connects to the LINE Messaging API.

✅ Real-World Use Cases:

  • Parental Organization: Keep track of school newsletters, event schedules, and permission slip deadlines for your children without reading lengthy emails.
  • Personal Finance Management: Get instant alerts for bill payment due dates, subscription renewals, or bank notifications.
  • Shopping and Promotions: Quickly identify valuable, time-sensitive offers or coupon codes from promotional emails.
  • Work-Life Balance: Stay informed about urgent work emails after hours without needing to constantly check your inbox. The summary helps you decide if a reply is needed immediately.
  • Freelancer/Consultant: Efficiently track project updates, meeting requests, and client deadlines from multiple sources in one streamlined feed.
