Workflow Architecture
Inside the Automation
Intelligent Inbox Management Agent — n8n workflow: Gmail Trigger → AI Agent → Switch → Telegram/Google Sheets routing
Gmail Trigger → AI Agent (GPT-4o) → JavaScript → Switch → Category routing (Telegram + Gmail labels + Google Sheets) + Error Trigger
Email Routing Logic
🔴 High Priority
Immediate Telegram Alert
Critical emails are instantly flagged and sent as a Telegram notification, plus labeled in Gmail and logged to Google Sheets for full traceability.
Telegram + Gmail Label + Sheets
🔵 Support
Labeled & Logged for Review
Support emails receive a Gmail label, a drafted AI response, and are appended to the Support sheet row — ready for human review and one-click send.
Gmail Label + Google Sheets
🟡 Billing
Categorized & Recorded
Billing-related emails are sorted, labeled, and appended to a dedicated Billing sheet with extracted amounts, sender info, and AI-drafted reply.
Gmail Label + Billing Sheet
⚫ Promotions
Auto-sorted & Archived
Promotional emails are silently labeled, logged to a Promotions sheet, and kept out of your main inbox — reducing noise with zero manual effort.

Who Is This For?
Built for people drowning in email
Business Owners & Founders
You're running a business, not an inbox. This agent handles email triage so you only see what truly needs your attention — high priority items, nothing else.
Customer Support Teams
Stop manually sorting tickets. The agent categorizes every support email, drafts a response, and queues it for one-click approval — slashing response times dramatically.
SMEs & eCommerce Stores
Billing queries, order issues, and promotional blasts all handled automatically. Your team wakes up to a pre-sorted, pre-drafted inbox every morning.
Automation Agencies
Offer this as a premium done-for-you service. The modular, client-ready design includes comment nodes and placeholder credentials — perfect for handoff.
How It Works
Step-by-step breakdown
1
Gmail Trigger fires on every new email
The workflow watches your Gmail inbox in real time. The moment a new email arrives, it's captured and passed into the pipeline — no manual checking, no delays.

2
AI Agent reads, classifies & drafts a reply
GPT-4o or Claude 3.5 Sonnet analyzes the full email — sender, subject, and body. It assigns a category (High Priority, Support, Billing, Promotion), an Actionability Score from 1–5, and writes a professional, empathetic draft response tailored to the context.

3
JavaScript formats the structured output
A Code node parses the AI's structured JSON output — extracting the category, score, and draft reply — and prepares clean data for the routing logic downstream.

4
Switch node routes to the right action
Based on the AI's category decision, the Switch node routes the email to one of four paths — each with its own Gmail label, Google Sheets log, and (for urgent emails) an instant Telegram alert.

5
Human-in-the-loop approval for replies
No email is ever sent automatically. Draft replies are logged to Google Sheets with an approval flag. You review, edit if needed, and trigger send with a single click — keeping you in full control.

Error Trigger catches and alerts on failures
A dedicated Error Trigger node monitors the entire workflow. If anything fails — API timeout, credential issue, or unexpected data — you receive an immediate Telegram notification so nothing slips through unnoticed.

Missed Urgent Emails
High-priority emails trigger an instant Telegram alert — you'll always know the moment something critical lands in your inbox.
Reclaim hours every week
Email triage is one of the biggest hidden time drains in any business. This agent handles classification, labeling, and draft creation automatically — giving your team back hours they'd otherwise spend sorting.
Consistent, professional replies every time
AI-drafted responses are always polite, empathetic, and on-brand. No more rushed replies or inconsistent tone — every draft meets the same high standard before it reaches a customer.
You stay in control — always
The human-in-the-loop safeguard means no email is sent without your approval. The AI does the heavy lifting; you make the final call. It's automation with accountability built in.
Full audit trail in Google Sheets
Every email processed, every category assigned, every draft created — all logged to Google Sheets. You get a clean record of every inbox action for reporting, compliance, or team reviews.
Modular & ready to scale
Built with clean, named credentials and comment nodes for easy handoff. Add new email categories, connect a CRM, or plug in additional AI tools without rebuilding from scratch.
