Vet new Form.io leads with ZeroBounce and sync qualified contacts to Pipedrive

Form.io to Pipedrive: Advanced ZeroBounce Lead Vetting

This workflow automates the transition of new Form.io submissions into Pipedrive, using ZeroBounce for multi-layer validation (Validation + AI Scoring).

Results are also output to Google Sheets for review.

🚀 How it Works

1. ⚡ Trigger & Verification: Activates on new Form.io submissions 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 person in Pipedrive.
• Invalid: Logs to a Google Sheet 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 Pipedrive.
• Medium/Low Score: Suppressed and added to a Google Sheet with the assigned score for review.

5. 📤 Output Results:

• Accepted: Output validation and scoring results to Accepted and Pipedrive
• Rejected Output validation and scoring results to Rejected.

💡 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).
