Overview

End-to-end lead validation from form submit to CRM, with immediate user feedback.

The AI agent verifies email health in real time as users submit your form, preventing invalid addresses from reaching your CRM. If the email is valid, the lead is created or updated in your CRM and the user sees a Success page. If invalid, the gate keeps the lead out, shows a clear error, and lets the user re-enter a valid address without losing form progress.

Example

Example workflow

A concrete scenario showing end-to-end results.

A user visits a product signup page and submits the form with an email. The AI agent checks the address in real time via NeverBounce. If valid, a new contact is created in HubSpot and the user is shown a Success page; if invalid, the user sees a tailored error message and can re-enter the address without leaving the page.

Common questions about setup, data, and behavior.

No specialized coding is required. The flow uses no-code triggers and standard connectors to perform verification and CRM updates. It runs inside your existing form stack and can be configured through a visual editor. You can customize the verification thresholds and error messaging without writing code.

Invalid emails are blocked at the gate and not sent to the CRM. The user sees a tailored error message and is guided to re-enter a valid address. The system logs the failed attempt for auditing and troubleshooting. Re-entry is allowed on the same page with preserved form progress.

Yes. You can tailor the error text and UI to match your brand and UX. Messages can be localized or adjusted for different validation scenarios. Custom errors help direct users to correct typos or switch addresses without abandoning the form.

The agent supports common CRMs like HubSpot and Salesforce and can be extended to others via API mappings. You map fields for lead or contact creation to ensure data is stored correctly. The verification result is tied to each CRM record for auditability. In multi-CRM setups, the flow routes verified leads to the appropriate instance.
