I wonder if you can help. I have created an email with a image header, it looks fine in Marketo but everytime i send it to myself it wont show the images. Am i doing something wrong?
It could also be as simple as your email system being set to not download images (most are set to not download by default).
Do you see an option that prompts you to display images when you open the email or does it look more like your image links are broken when you receive it? If it's the latter, it might have to do with where you're hosting your images (although I would tend to doubt this if your email is rendering properly in the Marketo editor).
