Why validate form emails with ZeroBounce in ConvertFlow
ConvertFlow's ZeroBounce integration lets your forms validate email addresses with your own ZeroBounce account. Connect your ZeroBounce API key once, then choose ZeroBounce as the validation source on any form's email field.
It's a fit when you already pay for ZeroBounce and want the same validation rules on your ConvertFlow forms, with results from your own ZeroBounce account instead of ConvertFlow's built-in validation.
ConvertFlow's built-in email validation stays the default. Nothing changes on your forms unless you switch a form's email field to ZeroBounce.
Connect ZeroBounce to ConvertFlow
- In ConvertFlow, open your website and go to Settings > Integrations.
- Find ZeroBounce in the Validation category.
- In your ZeroBounce account, copy your API key. Use the server-side API key, not a public or client-side key.
- Paste it into the API Key field in ConvertFlow and connect.
ConvertFlow checks your key when you connect.
Use ZeroBounce on your form
- Open your campaign in the funnel builder and select the Form element.
- Make sure the Email address field is toggled on, then open its field settings.
- Turn on Validate Email Is Real.
- In the Validation Integration dropdown, choose ZeroBounce.
- Optionally turn on Allow Business Emails Only and customize the Validation Message.

The Validation Integration dropdown only appears after Validate Email Is Real is on, and only lists integrations you've connected. It defaults to ConvertFlow.
What happens when a visitor submits
When a visitor submits the form, ConvertFlow checks their email with your ZeroBounce account before the form is submitted.
- Valid: the email is accepted and the form submits.
- Catch-all (accept-all domains): accepted. Catch-all addresses can't be fully verified, so they're allowed through.
- Invalid, spamtrap, abuse or do-not-mail: blocked. The field shows your Validation Message and the submit button is disabled until the email is changed.
- Disposable, toxic or possible trap: blocked, same as above.
- Unknown: accepted, so real visitors aren't turned away when ZeroBounce can't decide.
Set the message visitors see
If the email is blocked, visitors see the message you set in Validation Message. If you haven't set one, they see "Please enter a valid email address" (or "Please enter a business email" when Allow Business Emails Only blocks a free-email address such as Gmail).
If validation can't run
The form still submits. To avoid losing leads, ConvertFlow lets the visitor through when it can't get a result. This covers a missing or invalid API key, ZeroBounce being unreachable, or no response within 10 seconds.
