I sent out an email with a podcast player embedded into the email and it looked fine and played fine in the preview but when I got my email (along with 300 others that sent out), it showed up as just a blank space! So I had to send another email using the link as a text link in order for it to show up but they had to click out to get to it rather than it being embedded. Why would the podcast player appear embedded in the email in the preview but not in the actual email? That was embarrassing!
