This article provides a complete, practical walkthrough of the Http Emailreadimap Send Webhook n8n agent. It connects HTTP Request, Webhook across approximately 1 node(s). Expect a Intermediate setup in 15-45 minutes. One‑time purchase: €29.

What This Agent Does

This agent orchestrates a reliable automation between HTTP Request, Webhook, handling triggers, data enrichment, and delivery with guardrails for errors and rate limits.

It streamlines multi‑step processes that would otherwise require manual exports, spreadsheet cleanup, and repeated API requests. By centralizing logic in n8n, it reduces context switching, lowers error rates, and ensures consistent results across teams.

Typical outcomes include faster lead handoffs, automated notifications, accurate data synchronization, and better visibility via execution logs and optional Slack/Email alerts.

How It Works

The workflow uses standard n8n building blocks like Webhook or Schedule triggers, HTTP Request for API calls, and control nodes (IF, Merge, Set) to validate inputs, branch on conditions, and format outputs. Retries and timeouts improve resilience, while credentials keep secrets safe.

   Automate Your Inbox: Using n8n and AI to Summarize Emails and Send Key Info to LINE Messenger
   
   Managing email is a never-ending task — especially when important messages get lost in a sea of promotions, updates, and spam. But what if you could use AI to identify what really matters, summarize messages in plain language, and have the essential info pushed directly to a messaging app like LINE?
   
   This is exactly what you can achieve with a simple n8n no-code/low-code automation workflow. In this guide, we’ll break down how you can pull emails automatically, summarize their content using a powerful AI model via OpenRouter, and deliver summarized updates directly to yourself via LINE Messenger.
   
   Let’s walk through how this workflow works and how to build it yourself.
   
   🔧 Overview of the Workflow
   
   This n8n workflow titled “Summarize emails with AI then send to messenger” consists of three primary steps:
   
   1. Read incoming emails using IMAP.
   2. Send email content to an AI model (LLaMA 3.1 via OpenRouter) for summarization.
   3. Send the summary to a LINE Messenger recipient.
   
   The result? You receive concise, actionable summaries of your inbox messages via a messaging platform you check frequently — all powered by automation.
   
   Step 1: Connecting to Your Email via IMAP
   
   The workflow begins with the "Read emails (IMAP)" node. This node securely connects to your email inbox using the IMAP protocol — supported by nearly all email services including Gmail and Outlook.
   
   📌 Tip: Make sure IMAP is enabled in your email account settings. For Gmail users, follow this guide.
   
   The node scans your inbox for new messages. Once emails are retrieved, the content is passed on to the next node for processing.
   
   Step 2: Summarize Content with AI Using OpenRouter
   
   Now comes the magic. The “Send email to A.I. to summarize” node sends the full body of the email, including the sender and subject line, to OpenRouter’s API, leveraging the LLaMA 3.1-70B Instruct language model.
   
   Here’s what makes this setup clever:
   
   - Unimportant emails are summarized in fewer than 10 words.
   - Urgent items include emojis to help them stand out.
   - Action items and DEADLINES are highlighted in bold.
   - Personalized instructions ensure summaries are timely and concise.
   
   A custom JSON payload is sent via an HTTP request that includes a prompt carefully designed to instruct the AI exactly how to behave. The AI response returned is optimized to provide only crucial info and keep things readable — no fluff.
   
   To get started with OpenRouter.ai:
   
   - Sign up for a free OpenRouter account.
   - Use the model “meta-llama/llama-3.1-70b-instruct:free”.
   - For authentication, set up HTTP Header Auth in n8n:
     - Username: Authorization
     - Password: Bearer {your_API_key}
   
   Step 3: Send the Summary to LINE Messenger
   
   Once the email has been summarized, it's time to deliver that summary straight to your smartphone using LINE Messenger. The “Send summarized content to messenger” node handles this via a simple HTTP request to the LINE Messaging API.
   
   Rather than using the older native LINE node (which is outdated), the workflow uses a custom HTTP POST call, allowing for more flexibility and reliability.
   
   Here’s what you need:
   
   - A LINE Messaging API account and channel.
   - A channel access token from the LINE Developers Console.
   - Use HTTP Header Auth again:
     - Username: Authorization
     - Password: Bearer {your_channel_access_token}
   
   With the setup complete, the summary is pushed to your LINE account instantly.
   
   🔐 Handling Authentication
   
   This workflow involves connecting to two external APIs: OpenRouter and LINE. Both require secure tokens. In n8n, these are managed using “HTTP Header Auth” credentials. Store them safely and never expose your API keys.
   
   Here’s how to format them:
   
   - Authorization header key
   - Value: Bearer {API key or token}
   
   📝 Enhancing the Experience
   
   Want to customize your workflow further?
   
   - Add a filter to only pull unread or labeled emails.
   - Schedule the workflow to run every hour, or use a webhook for real-time triggers.
   - Integrate with Google Calendar to create events for action items with deadlines.
   - Send summaries to multiple recipients or group chats.
   
   🎯 Why This Matters
   
   This workflow was originally created for a real-life scenario — a parent overwhelmed by school-related email communication. By summarizing emails and highlighting deadlines or registration due dates, they avoided missed school events, payments, and teacher communications.
   
   In their words, “AI saved my kid’s school life — and my marriage.”
   
   Whether you're juggling work emails, client messages, or school notices, this workflow is an excellent example of how automation and AI can simplify your digital life.

   Automate today, and never miss an important email again. With n8n, OpenRouter, and LINE Messenger, you can build smart, human-centered automations that actually improve your everyday life.

5. Set credentials for each API node (keys, OAuth) in Credentials.
6. Run a test via Execute Workflow. Inspect Run Data, then adjust parameters.
7. Enable the workflow to run on schedule, webhook, or triggers as configured.

Tips: keep secrets in credentials, add retries and timeouts on HTTP nodes, implement error notifications, and paginate large API fetches.

Validation: use IF/Code nodes to sanitize inputs and guard against empty payloads.

Why Automate This with AI Agents

AI‑assisted automations offload repetitive, error‑prone tasks to a predictable workflow. Instead of manual copy‑paste and ad‑hoc scripts, your team gets a governed pipeline with versioned state, auditability, and observable runs.

n8n’s node graph makes data flow transparent while AI‑powered enrichment (classification, extraction, summarization) boosts throughput and consistency. Teams reclaim time, reduce operational costs, and standardize best practices without sacrificing flexibility.

Compared to one‑off integrations, an AI agent is easier to extend: swap APIs, add filters, or bolt on notifications without rewriting everything. You get reliability, control, and a faster path from idea to production.

Best Practices

• Credentials: restrict scopes and rotate tokens regularly.
• Resilience: configure retries, timeouts, and backoff for API nodes.
• Data Quality: validate inputs; normalize fields early to reduce downstream branching.
• Performance: batch records and paginate for large datasets.
• Observability: add failure alerts (Email/Slack) and persistent logs for auditing.
• Security: avoid sensitive data in logs; use environment variables and n8n credentials.

FAQs

Can I swap integrations later? Yes. Replace or add nodes and re‑map fields without rebuilding the whole flow.

How do I monitor failures? Use Execution logs and add notifications on the Error Trigger path.

Does it scale? Use queues, batching, and sub‑workflows to split responsibilities and control load.

Is my data safe? Keep secrets in Credentials, restrict token scopes, and review access logs.
