Verify form leads in real time with NeverBounce before adding to your CRM

Description

Stop lead pollution at the source.
This workflow creates a "Gatekeeper" for your web forms, ensuring that only 100% valid email addresses ever reach your CRM.

How it works:

Instant Verification: As soon as a user submits your n8n form, their email is sent to NeverBounce for a real-time health check.
The "Clean" Path: If the email is valid, the lead is automatically created/updated in your CRM (HubSpot, Salesforce, etc.) and the user sees a "Success" page.
The "Gatekeeper" Loop: If the email is invalid or disposable, the workflow blocks the entry, shows a custom error message, and allows the user to re-enter a valid address without losing their place.

Why use this?

Protect Domain Reputation: Stop your sales team from sending to "undeliverable" addresses.
Save CRM Costs: Keep your contact database lean by only paying for real, reachable humans.
Better UX: Instead of a generic failure, users get immediate feedback to fix typos in real-time.
