My newsletter looks wrong in Windows 10 Mail. What can I do?
HTML/CSS newsletters cannot differentiate between Windows 10 Mail and Outlook, even though Windows 10 Mail and Outlook have different behavior and render the same content differently.
This means that it's only possible to have a newsletter render correctly in either Windows 10 Mail or Outlook 2013, not both. Due to Outlook 2013 being in more widespread use, we decided to provide correct rendering in Outlook 2013.
