Gmail Lead Reply Intent Routing in n8n (OpenAI, Pipedrive, Slack)

Automatically route Gmail lead replies to the right follow-up—using OpenAI intent classification

This n8n workflow monitors your Gmail inbox for lead replies, matches each sender in Pipedrive, classifies intent and urgency with OpenAI (GPT-4o), then creates the correct Pipedrive activity and notifies the deal owner in Slack.

What this workflow does

Designed for sales and SaaS teams using n8n, it automates the “reply triage” process so you spend less time sorting emails and more time acting on them.

• Every minute, the workflow triggers when a new email arrives in your Gmail inbox.
• It extracts and cleans the sender name/email, subject, and the message snippet for analysis.
• It searches Pipedrive for a matching person by the sender’s email address; if no match is found, it emails an internal reviewer.
• It sends the email details to OpenAI (GPT-4o) to produce JSON that classifies intent, buying stage, sentiment, urgency, and a recommended next action.
• It normalizes the AI output and routes the reply to the correct path: Meeting Request, Pricing Inquiry, Follow Up Later, or Not Interested.
• It creates a corresponding Pipedrive activity (meeting, call, or mail) or marks the deal as lost for Not Interested, then logs the full AI analysis in a Pipedrive note.
• Finally, it posts a Slack message to the deal owner with the AI summary and recommendation, and emails an internal summary as well.

Use cases

• Turn inbound sales replies into scheduled meetings without manual tagging.
• Auto-handle pricing questions by generating the right follow-up activity in Pipedrive.
• Flag “not interested” responses by marking deals lost automatically and notifying owners.
• When lead urgency is high, prioritize actions using OpenAI’s urgency classification.
