This automation ensures no high-value lead falls through the cracks, every inquiry gets the right response speed, and you build a data-driven picture of your event pipeline over time.\n\n### **How it works:**\n- Gmail Trigger monitors your inbox for new event-related emails\n- Google Gemini #1 analyzes sentiment (Positive / Neutral / Negative)\n- Google Gemini #2 extracts topic, intent, urgency, org, budget signals\n- Every email is logged to the `email_analytics` Data Table + Google Sheets\n- Every email upserts a **Salesforce Lead** (deduped by email) with sentiment + enrichment\n- Hot leads (Positive + urgency >= 7) auto-create **Salesforce Opportunities**\n- Every lead gets a **Salesforce Task** with the AI-suggested follow-up action\n- Google Sheets feeds a **Looker Studio** dashboard for real-time visual analytics\n- Positive → Hot Lead email + Slack #hot-leads (respond within 2h)\n- Neutral → Follow-up email + Slack #follow-ups (nurture within 24-48h)\n- Negative → Insights email + Slack #insights (log for marketing strategy)\n\n### **Setup steps:**\n1. Connect your **Gmail** OAuth2 credential\n2. Connect your **Google Gemini** API credential\n3. Connect your **Slack** OAuth2 credential\n4. Create the `email_analytics` **Data Table** and update the table ID in the Log node\n5. Update recipient email addresses in Send Email nodes (currently placeholders)\n6. Verify Slack channels `#hot-leads`, `#follow-ups`, `#insights` exist\n7. Connect your **Salesforce** OAuth2 credential (Setup > App Manager > New Connected App)\n8. Create 9 custom fields on the Salesforce **Lead** object: `Sentiment__c`, `Sentiment_Confidence__c`, `Primary_Topic__c`, `Lead_Intent__c`, `Urgency_Score__c`, `Budget_Mentioned__c`, `Event_Referenced__c`, `Email_Domain__c`, `Last_Email_Subject__c`\n9.
