Analyze Customer Sentiment with Zoho CRM, Google Gemini & Send Gmail Alerts

Description

Zoho CRM → AI Sentiment Analysis for customer interactions & Automatic Alerts Workflow

This workflow analyzes newly created Notes (in Any module) in Zoho CRM, detects customer sentiment using an AI model, updates the related CRM record with custom fields - sentiment label and score, and sends an instant alert whenever negative sentiment is detected. It runs on a scheduled interval and gives teams real-time visibility into customer emotions and potential risks.

Quick Implementation Steps
Connect Zoho CRM OAuth2 credentials
Add custom fields in Zoho CRM: Sentiment_Label and Sentiment_Score
Add AI provider credentials
Set Gmail alert recipient
Activate workflow and test by adding a Note

What It Does
This workflow automatically monitors Zoho CRM Notes. When a new Note is detected, the text is extracted and analyzed through an AI-powered sentiment model. The AI classifies the text as Positive, Neutral or Negative and produces a numeric sentiment score.

The workflow updates the related CRM module with these values. If the sentiment is negative, a Gmail alert is triggered so your team can follow up quickly. This automation helps organizations maintain high customer satisfaction and detect potential issues early.

Sales teams
