No, embedding surveys, videos, or forms directly into your template or campaign is not supported. In many cases, the receiving email client will strip out embed code.
Instead of editing the HTML code to embed any of these items, we recommend creating a button, image, or text link that will click out your form, video, or third party survey from the email. Great survey vendors include SurveyMonkey, GetFeedback, and Formstack.
GetFeedback allows you to embed one question surveys directly into the HTML of your email for quick surveys like NPS or post-event satisfaction. Learn more here. This process works in the drag-and-drop editor.
