Merging emails + data from multiple questionnaires in Jotform

Hi there,

We have 3 Jotform questionnaires that will be collecting data and customer information that we want to send to Klaviyo. Form 1 is so we can capture customer data and email even if they don’t sign up. Form 2 is additional information that we do not ask for the email on. Then the final form is payment.

My question is, if the customer uses the same email in form 1 and form 3, will this merge this customer in Klaviyo?

Also, as we don’t have any contact/information collected in form 2 - can this information feed through? We are tracking submission id in Jotform.

Thanks
