Automate Gmail Lead Follow-Up with OpenAI GPT-4O, HubSpot, Slack & Google Sheets

How it works

This workflow automates the handling of new lead responses received in Gmail. It captures emails with a specific label, analyzes the message using AI to determine sentiment, intent, urgency, next action, and priority, and then decides whether follow-up is needed. If required, it creates tasks in HubSpot, notifies the sales team via Slack, and logs all details into Google Sheets for tracking.

Step-by-step Trigger on New Lead Email

Workflow starts whenever a new email with a defined Gmail label arrives.

Captures the sender’s email, subject, message snippet, and timestamp.

Normalize Email Data

Standardizes Gmail fields into structured values:

leadEmail (sender’s address)

subject (email subject)

message (email content snippet)

source (Gmail)

receivedAt (timestamp)

AI-Powered Lead Analysis

Uses OpenAI to analyze the lead’s message.

Extracts:

Sentiment (Positive / Neutral / Negative)

Intent (Interested, Not Interested, Needs Info, Ready to Buy, Objection)

Urgency (High / Medium / Low)

Next Action (Call, Email, Demo, Quote, No Action)

Summary (1–2 sentence description)

Priority (Hot / Warm / Cold)

Parsed results are merged with the original email data.

Flags are added:

needsFollowUp (true/false)

isHighPriority (true/false)

Decision: Needs Follow-Up?

If AI suggests a follow-up action, the workflow continues.

Otherwise, the process stops here.
