AI-Powered Automation:
AI-Powered Customer Support Automation
Overview
The platform currently provides:
Gmail Webhook Trigger
Initiates the workflow upon the arrival of new emails in a specified Gmail inbox instantly.
Smart Email Filtering & Extraction
Identifies and ignores internal/outbound emails; extracts message content and full conversation threads.
OpenAI Image Analyser (OCR / Vision)
Analyses image attachments such as bill screenshots and product box images to extract Order IDs from unstructured data.
Conversation Summarisation
AI-powered summarisation of the current email query and full previous conversation history.
Query Relevance Check
Determines if an email is a legitimate support query or promotional/irrelevant, marking the latter as read without processing.
Knowledge Base AI Agent
Utilises Google Sheets as a dynamic knowledge base for answering questions including company policies, order status, and tracking links.
Priority Escalation & Notification
Identifies high-priority cases (returns, refunds, cancellations), labels in Gmail, and notifies the customer immediately.
Automated Email Reply
Crafts and sends structured email replies for AI-handled queries and specific notifications for escalated cases.
Challenges
Slow Response Times:
Customers waited 2–8 hours for replies on order status, returns, and complaints — leading to frustration and cart abandonment.
High Support Agent Load:
Human agents were overwhelmed with repetitive queries like order status checks and return requests, leaving complex issues unattended.
No 24×7 Coverage:
Support teams operated in limited hours, leaving customers without help during evenings, weekends, and peak sale events.
Inconsistent Responses:
Manual replies varied in tone, accuracy, and completeness — damaging brand trust and creating poor customer experiences.
Objectives / Goals
Handle all customer queries directly on Gmail :
Without redirecting users to other platforms, keeping the full support experience within the email interface.
Use AI to understand intent and generate human-like responses :
OpenAI GPT processes context, history, and the knowledge base for accurate, contextual replies.
Support both pre-order and post-order query types intelligently :
From product availability and pricing to order tracking, returns, and complaints.
Analyse customer-sent images for damaged or incorrect order resolution :
Extract Order IDs from bills, screenshots, and product box photos via OpenAI Vision.
Provide 24×7 instant support without increasing team headcount :
Replacing repetitive agent effort with fully automated AI-driven responses.
Fetch real-time order data via API integration :
Using extracted Order IDs or phone numbers to surface live status and tracking in every reply.
Scale efficiently during peak sales without performance degradation
Handle unlimited simultaneous queries automatically.
Solution
Built using n8n, the automation uses modular nodes to connect Gmail, OpenAI, Google Sheets, REST APIs, and Postgres to process, classify, and respond to every inbound support email in real time.
Workflow Logic
Gmail Webhook Trigger:
A Webhook node is triggered by Gmail upon receiving a new email — instant, no polling.
Sender Check & Filtering:
A Code node checks if the email is from the internal side. If yes, it is marked as read and ignored. If not, the workflow proceeds.
Attachment OCR Analysis:
Thread Retrieval:
Conversation Summary & Query Formulation:
Relevance Check & Routing:
AI Agent Processing:
The AI Agent receives the customer query and summarised context. It queries Google Sheets for knowledge base information and makes API calls to fetch live order details.
Priority Assessment:
The AI Agent assesses if the query requires high priority — specifically checking for returns, refunds, or cancellations.
Priority Escalation (if High Priority):
The email is labelled High Priority in Gmail. A notification email is sent to the customer confirming escalation to the senior team. No AI reply is generated for these cases.
Automated Reply (Standard Cases):

Use Cases
Order Tracking:
Customer asks "Where's my order?" — the system fetches live tracking status and replies in seconds without any agent involvement.
Returns & Refunds:
Automates return eligibility checks and guides the customer through the process — escalates to human for final approval.
Pre-Purchase Queries:
Answers questions on pricing, product variants, and stock availability before checkout — reducing drop-off and boosting conversion.
Damaged Order Handling:
Customer sends a photo of a damaged product — AI processes the image, extracts the Order ID, and initiates the resolution flow.
Policy-Based Answers:
Shipping, warranty, and privacy policy questions answered accurately and instantly from the Google Sheets knowledge base.
Providing Order Status:
Automatically informs customers about the current status of their orders using the extracted Order ID and live API data.
Sharing Tracking Links:
Shares shipment tracking links directly in the reply — no human lookup required.

Instant firing on new email arrival. No polling, no delay — every message processed the moment it lands.
Smart Email Filtering
Outbound and internal emails automatically identified and ignored without any manual intervention.
OpenAI Vision (OCR):
Bills, screenshots, and box images processed to extract Order IDs with no human review.
Conversation Summarisation :
Full thread history summarised by AI before processing — enabling context-aware responses even for long threads.
Knowledge Base AI Agent:
Google Sheets integration enables real-time lookup of company policies, FAQs, and product information.
API Order Data Fetch
Live order status and tracking links pulled via REST calls using the extracted Order ID.
Priority Escalation Engine :
Returns, refunds, and cancellations automatically flagged, Gmail-labelled, and routed to human agents.
Structured Auto Reply
AI-crafted, contextual replies sent immediately for all standard queries with no agent involvement.
Manual Handover for Critical Cases
High-priority cases are never auto-replied. They are routed to a support person with full context attached.
Limitations
The following limitation applies to this system:
Manual Handling of Specific Requests: The AI agent does not completely handle return, refund, or cancellation requests. These query types are automatically escalated to high priority and require manual review by a human support agent to verify legitimacy and process appropriately.
