Success Stories
Turning Inbox Overload into a Smart Lead System with n8n and AI
From Inbox Overload to Smart Automation
As the business grew, so did the number of incoming emails. For this mid-sized tech company, hundreds of messages arrived every day from potential clients, job applicants, and partners, all landing in the same shared inbox.
The team had to review, sort, and forward each email manually. It took hours every day and often slowed down responses to potential leads.
They wanted a smarter way to manage this without hiring more people or investing in expensive enterprise tools.
The project focused on redesigning the Web store with part of backend systems to deliver a modern, localized experience.
The Challenge
Before automation, every task was handled manually. This meant:
- Qualifying and sorting every lead by language and country before passing it to the right sales representative.
- Forwarding HR-related emails to the HR team.
- Logging new leads into HubSpot by hand.
- Filtering out spam and irrelevant messages.
- Spending up to two hours processing a single lead from start to finish.
It was repetitive, time-consuming, and prone to human error. Most importantly, potential clients often waited too long for a response.
The Solution
Using n8n, Manao Software built an intelligent automation workflow powered by AI. The new system now:
- Classifies emails automatically using an AI model (LLM) that identifies whether the message is a lead, HR inquiry, or spam, and extracts key details such as company name and requested service.
- Routes leads instantly to the right sales representative based on language and territory.
- Integrates seamlessly with HubSpot, creating new lead records, assigning tasks to respond, or updating existing ones with relevant notes.
- Notifies sales reps in real time via Microsoft Teams when a new lead is assigned.
- Directs HR emails to the HR team automatically.
- Filters spam before it reaches anyone’s inbox.
The Result
After implementation, the improvement was immediate and measurable.
- Lead assignments now take under one minute, compared to up to two hours before.
- Manual triage work dropped by 80%, freeing several hours each day for higher-value marketing work. A human is still brought into the loop when the AI is not sure.
- Sales teams can respond to leads faster and more consistently.
- CRM data in HubSpot is now cleaner, more accurate, and easier to track.
- Only qualified leads reach the sales team, improving lead quality and conversion rates.
