What report allows you to see how successful or active a form has been on...

Form reports show the performance and activity of your Marketing Cloud Account Engagement forms, which are web forms that capture prospect information. You can use form reports to see how many prospects have viewed, completed, or started but not completed your forms, as well as the conversion rate and average time to complete. You can also drill down into individual form submissions and view the prospect’s details and activities. References: [Form Reports], [View Form Reports]
