When a new form submission received in Unbounce, validate the email using ZeroBounce, and add a new subscriber in Campaign Monitor
Unbounce landing page leads have their email checked by ZeroBounce, then go into Campaign Monitor as subscribers, with ZeroBounce’s verdict available for you to act on with a Filter.

What this workflow does
Landing pages bring in a lot of sign-ups during a campaign, and some of them come with mistyped or throwaway addresses. Emails sent to those addresses bounce. This workflow runs each Unbounce lead's email through ZeroBounce before it is added to Campaign Monitor, so you have the result at the point where it can still change what happens.
When a visitor submits a form on an Unbounce page, FlowMattic takes the email from the submission and passes it to ZeroBounce using Verify Single Email. ZeroBounce returns its result for that address. The third step adds the lead to the list you choose in Campaign Monitor with the fields you map.
As shipped, the subscriber step runs for every lead whatever ZeroBounce returns, because no step reads the result. That still gives you a record of each check in Task History. To add only good addresses, place a Filter between the two steps and set it to the value ZeroBounce uses for a valid email.
Webinar sign-up pages
People who register through an Unbounce page are checked and then added to a Campaign Monitor list used for the reminder emails.
Paid ad campaigns
Leads from ad traffic often include fake addresses. Checking each one with ZeroBounce shows you which sign-ups from a campaign are real.
Ebook or checklist downloads
Visitors who swap their email for a download join your Campaign Monitor list, and a Filter on the result keeps bad addresses out.
How this workflow runs
What happens at each step once the workflow is on, and what you need before you import it.
Unbounce New Form SubmissionRuns for each lead captured by a form on your Unbounce pages. The email and other answers become values for the next two steps.
ZeroBounce Verify Single EmailChecks the lead's email address with ZeroBounce. Map the email from the Unbounce submission and connect your ZeroBounce account. The verdict is then available to map or filter on.
Campaign Monitor Add SubscriberAdds the lead to the Campaign Monitor list you select. Map the email and name from the Unbounce form. As imported, this runs for every lead, valid or not.
What you need
- FlowMatticCore
- Unbounce AccountAccount
- ZeroBounce AccountAccount
- Campaign Monitor AccountAccount
After importing, map your own data. To keep the template universal, not every step is pre-filled. Open each step in the builder and connect your accounts and fields (channels, lists, sheets, recipients) before you switch the workflow on.
Make it yours
Changes worth making after you import it.
- Put a Filter between ZeroBounce and Campaign Monitor that continues only when the status equals the value ZeroBounce gives a valid address. Look at a test run for that exact value.
- Use a Router instead if you want risky addresses kept apart, with one route adding valid leads to your main list and another adding the rest to a review list.
- If you run several Unbounce pages through one workflow, map the page name into a Campaign Monitor custom field if the step offers one, so you can tell where each subscriber came from.
Questions about this workflow
Does ZeroBounce stop bad Unbounce leads from reaching Campaign Monitor?
Not as imported. ZeroBounce returns a result, but nothing acts on it, so every lead is added. A Filter after the ZeroBounce step is what keeps bad addresses out.
Is the ZeroBounce check paid?
The check runs through your own ZeroBounce account, which you connect on import. ZeroBounce sets the terms for checks on that account.
What happens if the Unbounce lead is already on the Campaign Monitor list?
The step sends the address to the list again. Try it once with an address that is already subscribed and look at the response in Task History to see how your list treats it.
Do Unbounce leads still appear in Unbounce?
Yes. The workflow reads each submission and doesn't change anything in Unbounce, so your leads stay there as well.
