It would be nice to have the ability to send a survey within a workflow. For example, create an if/then branch on if a contact attended a webinar. If yes, then it sends a survey asking for feedback, if not, then no survey is sent. Surveys should have the same functionality within workflows that emails do. We have workflows set up for promoting webinars, and it would be so nice to just add a few branches to the workflow following the webinar to see how it went by sending a survey.
