I'm still quite new to Marketo so sorry for what could be a very basic question!
I'm trying to embed a video into a marketing campaign. I have added the embed code to the HTML of the text box and the preview looks good, however when I view the sample email (have tried both Outlook and Gmail), the video doesn't show. It does work though if I click "view in browser", but I need it to play in the email for our audience.
Does anyone know why this is happening?
