Gravity Forms email verification with BillionVerify
Gravity Forms is a leading WordPress form builder used for lead generation, registrations, and contact submissions. Pairing it with BillionVerify means every email entered into your forms is validated before it reaches your CRM or email list, stopping fake and mistyped addresses at the source.
Why verify before the send
Forms are the most common entry point for bad email data. Users mistype addresses, enter disposable inboxes to avoid follow-up, or use role addresses that bounce immediately. BillionVerify catches these at submission time, so your Gravity Forms data arrives clean and your downstream marketing or CRM workflows run on accurate contacts.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Gravity Forms sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key.

Ready-to-use workflows that verify emails before Gravity Forms sends.
How it works
- 1
Connect BillionVerify to Gravity Forms using n8n, Integrately, or the REST API via a Gravity Forms webhook or notification trigger.
- 2
When a form is submitted, the email field value is sent to BillionVerify for verification.
- 3
BillionVerify checks for syntax errors, domain validity, MX records, SMTP deliverability, and disposable or role-based patterns.
- 4
Based on the result, your automation can conditionally save the entry, trigger a confirmation email, or flag the submission for review.
- 5
Over time, track verification outcomes across forms to identify which sources generate the highest quality leads.
When to use this
Block invalid emails at form submission
Connect BillionVerify to your Gravity Forms submission webhook. When a visitor submits a form, their email is checked in real time. Invalid or disposable addresses are rejected before the entry is saved, keeping your leads database clean.
Filter registration forms for genuine users
For event registrations or account sign-ups built on Gravity Forms, verify each email address to ensure only real, reachable contacts proceed. This reduces no-show rates and eliminates fake registrations from your records.
FAQ
Can BillionVerify validate emails in real time when a Gravity Forms form is submitted?
Yes. By triggering the BillionVerify API via a webhook on form submission, you can check the email synchronously and conditionally handle the entry — all before it reaches your CRM or mailing list.
Will this work with Gravity Forms' existing notification and feed add-ons?
Yes. BillionVerify connects through standard webhooks or automation tools like n8n and Integrately, so it works alongside Gravity Forms' built-in notifications and CRM feeds without conflicts.
What is a role-based email and why should I filter it?
Role-based addresses like info@, support@, or sales@ are shared inboxes not tied to an individual. They often cause bounces or ignored messages. BillionVerify detects and flags them so you can handle them separately.
Can I retroactively verify emails already stored from past Gravity Forms submissions?
Absolutely. Export your existing form entries, run the email addresses through BillionVerify's bulk API, and use the results to clean your historical records before syncing them to a marketing platform.
