Fully automated inquiry routing across email and Messenger

Timeline
3 weeks — November to December 2025

Every growing business eventually hits the same wall: one shared inbox, multiple departments, and a team manually sorting through messages trying to figure out who should handle what.

For a Philippine herbal manufacturing company managing inquiries across email and Facebook Messenger — laboratory services, business development, HR, and general inquiries all landing in the same place — that wall arrived hard. Leads were getting buried. Responses were delayed. And the marketing team was spending hours every week doing what a system should be doing automatically.

The constraint: they couldn’t disrupt how they were already communicating with customers. No new platforms. No new inboxes. No workflow that required anyone to change how they worked. The automation had to slot into what already existed — and make it smarter.

The Challenge: One Inbox, Too Many Departments

The company ran all external communications through a single email address. Every inquiry — whether it was a laboratory testing request, a business partnership inquiry, a job application, or a general customer question — landed in the same inbox.

The result was predictable:

Lost leads — high-value business inquiries buried under routine messages, missed or responded to days late

Communication delays — the right department wasn’t seeing messages until someone manually forwarded them

Inconsistent customer experience — response tone, timing, and content varied depending on who checked the inbox that day

Marketing team overload — hours every week spent monitoring, sorting, and forwarding emails that a system should handle

On top of that, their Facebook page was generating Messenger inquiries that had no structured response system. Comments on posts went unanswered or got generic replies. Messenger conversations weren’t being captured or tracked.

💡 The non-negotiable constraint: the solution had to work with their existing email address and Facebook page. No new platforms for customers to learn. No disruption to the customer journey. The intelligence had to be invisible.

The Solution: Two Automation Systems, One Seamless Experience

I built two interconnected automation systems — one for email, one for Messenger — that together created a complete, intelligent communication layer over their existing channels.

System 1: AI-Powered Email Routing & Auto-Response

Every email sent to the company’s public inbox is now automatically intercepted, analysed, classified, and routed — before a human ever touches it.

AI Classification (OpenAI via Zapier) — each incoming email is analysed for intent, urgency, and department. The AI determines whether it’s a laboratory inquiry, business development opportunity, HR matter, or general question — and assigns an urgency level.

Department Routing — based on the classification, the email is automatically forwarded to the correct department with a structured summary: case ID, inquiry type, urgency label, and the original message content.

Branded Auto-Acknowledgement — the customer receives an immediate, professionally branded response confirming their inquiry was received, what department handles it, and the expected next step. Consistent every time, regardless of when they emailed.

Slack Notifications — each department’s dedicated Slack channel receives an instant notification when a new inquiry is routed their way — with a summary, urgency tag, and reference link to the monitoring sheet.

Google Sheets Logging — every processed inquiry is logged with department label, timestamp, AI summary, urgency tag, and status — giving the team full visibility into inquiry volume, response time patterns, and departmental workload.

System 2: ManyChat Messenger Automation

Facebook Messenger became a structured, scalable customer-facing channel — with two automation flows running in parallel.

Messenger Chatbot — a structured conversational flow greets visitors, helps them identify the right department, provides relevant information, and collects their email for future follow-up. If a user wants to speak to the team directly, the bot pauses and flags it for human handoff — no one gets stuck in a bot loop.

Comment Trigger Automation — when users comment on Facebook posts, the automation responds instantly with relevant information, event details, FAQs, or a CTA — turning post engagement into structured conversations without manual replies.

All Messenger interactions are logged in a separate Google Sheet — capturing user responses, department selections, and email addresses collected — building a nurturing list and giving the marketing team data on what inquiries Facebook is generating.

The Tech Stack

Six tools, two systems, one seamless communication layer:

Zapier
Automation orchestrator — connects all platforms, schedules workflows, handles routing logic
OpenAI
AI classification engine — reads, categorizes, and summarizes each email by intent and urgency
Gmail
Centralized inbox — existing channel retained, extended with intelligent routing and auto-response
Slack
Internal notification layer — departments get instant alerts with structured inquiry summaries
ManyChat
Messenger automation — chatbot flows, comment triggers, email collection, human handoff logic
Google Sheets
Monitoring and logging layer — full inquiry history, department performance, Messenger analytics

What Changed After Go-Live

The shift was immediate — and it happened without a single customer noticing the change.

Email management became fully hands-off. No manual sorting, no forwarding, no checking the inbox every hour. The system handles classification, routing, and acknowledgement automatically — 24 hours a day.

Departments get what they need immediately. Laboratory Services, Business Development, and HR each receive structured, summarised inquiries in their Slack channel the moment they arrive — no digging through a shared inbox.

Customers get faster, more professional responses. Every inquiry receives an immediate branded acknowledgement — regardless of the time of day or who’s available. The customer experience is consistent every single time.

Messenger became a lead capture channel. What was previously an unstructured Facebook comment section and DM inbox is now a structured channel that routes inquiries, collects contact details, and feeds into the team’s nurturing pipeline.

The team has visibility they never had before. The Google Sheets log gives leadership a clear picture of inquiry volume by department, response time patterns, and what’s coming in through Facebook versus email.

💬 The most important outcome: no customer had to change how they contacted the company. They still emailed the same address. They still messaged on Facebook. The intelligence was added behind the scenes — invisible to the customer, transformative for the team.

Is This Right for Your Business?

This kind of communication automation makes sense when:

1

You have a shared inbox receiving inquiries across multiple departments or categories

2

Someone is manually sorting, forwarding, or triaging emails as part of their daily workflow

3

You have an active Facebook page with inquiries coming through Messenger or post comments that aren’t being handled consistently

4

You want better visibility into what types of inquiries you’re receiving and how quickly they’re being resolved

You don’t need to overhaul your communication channels. You need an intelligent layer built on top of what you already use — one that handles the sorting, routing, and first response so your team can focus on the conversations that actually need a human.
