We use GoToWebinar for our webinar platform because it integrates with Marketo. We sync the GTW webinar with the appropriate Marketo program and run registrations through our Marketo landing page and form. We would like to cap our registrations at 1,000 (which I have already done so in GTW) and then send those who fill out the registration form after the 1,000th person to a new flow that will send them a "sorry we're full" email. We will then email this group of registrants the On-Demand recording post-webinar.
Does anyone know how to send individuals to a new flow once 1,000 people have filled out a form? Trying to think through this but would love some suggestions!
