I'd like to send an email to a list of registrants that contains a survey. I browsed through Marketo's product docs page and on communities posts, but it seems like Marketo does not offer an in-house survey feature. Instead, people will integrate external survey tools like Survey Monkey or create a landing page with custom form / form fields to collect information. Is there a best practice when it comes to pointing registrants to a survey from an email? What's a trusted third-party survey platform?Can you advise? I'm posting a LaunchPoint article I found (link is below). Thanks!
