Here you can learn about including external content from some common providers in your emails.
Most external content providers supply a HTML snippet to paste into your email layout. Voyado does not recommend using this method as it can be tricky to make it blend in your layout. Instead, use dynamic images and the links provided to build the layout in Design Studio.
Design Studio will just link to the image provided. It cannot change the image or edit any text inside the image. That needs to be done in the external system. Images with a small size may also appear blurred on high resolution (Retina) screens as they might be scaled up.
