We have a responsive email template on campaign monitor. Some recipients with Outlook 2007 and 2010 see an empty windows or just gray bars instead of the whole email campaign. There might be also some other email client with similar problems. In addition, we would like to improve the CTA. Almost all modules have CTAs. When our user delete the CTA, there is too much space after the last line of the element.
PS. We are working with layouts. That enables us to order, add and remove the layouts (opening tag: <layout label='example'>)
