Vet new Shopify leads with ZeroBounce and sync qualified contacts to HubSpot

Shopify to HubSpot: Advanced ZeroBounce Lead Vetting

This workflow automates the transition of new Shopify customers into HubSpot, using [ZeroBounce](https://www.zerobounce.net) for multi-layer validation (Validation + AI Scoring).

Results are also output to Google Sheets for review.


🧩 Nodes used in this workflow - [ZeroBounce](https://n8n.io/integrations/zerobounce) - [Shopify](https://n8n.io/integrations/shopify) - [Hubspot](https://n8n.io/integrations/hubspot) - [Google Sheets](https://n8n.io/integrations/google-sheets) (or alternative e.g. [Data Table](https://n8n.io/integrations/data-table))

💡 Key Benefits - ✨ Zero-Waste Sync: Only "Valid" or "High-Scoring" leads reach your CRM. - 🛡️ Credit Safety: Internal checks ensure you never trigger an API call without credits. - 📊 Detailed Suppressions: Every rejected lead is categorized by reason (e.g. Email Missing, Invalid, Low Score, or Insufficient credits).

🚀 How it Works 1. ⚡ Trigger & Verification: Activates on new Shopify customers and first checks if an email address is provided. - Email present: Proceeds to credit check and validation - Email missing: Customer details are added to Rejected output for review with reason 'Email missing'. 2. 💳 Credit Management: Before each ZeroBounce call, the workflow checks your account for sufficient credits to prevent node failures. - Success: Proceeds to Stage 1 (Validation). - Failure: Customer details are added to Rejected output for retry with reason 'Not enough credits'. 3. ✔️ Stage 1: Email Validation: Validates the email address with ZeroBounce. - Valid: Adds the result to Accepted output and creates a contact in HubSpot. - Invalid: Logs to an n8n Data Table with the validation results and a reason for rejection for review. - Catch-all: Proceeds to Stage 2 (Scoring). 4. 🎯 Stage 2: AI Email Scoring: For "Catch-all" emails, the workflow requests ZeroBounce AI Scoring. - High Score (>=9): Syncs to HubSpot. - Medium/Low Score: Suppressed and added to an n8n Data Table with the assigned score for review. 5. 📤 Output Results: - Accepted: Output validation and scoring results to Accepted and Hubspot - Rejected Output validation and scoring results to Rejected.
