Outlook 2016 Email Format

Scott -

Unfortunately, Outlook desktop 2016 still uses Word and a bunch of proprietary XML to format email (the same as previous versions) and I don't think this situation is going to change any time soon and people have been complaining about it for years. If you want to create visually compelling HTML emails that will render with fidelity across a wide range of devices, you really need to compose them using a dedicated HTML editor, or a plain text editor for the best results. Of course there are also third-party services like Mail Chimp that help with the creation of responsive emails using their templates and online editors.

Another issue with Outlook that I've never solved (and perhaps just as important for Spam scoring) is how to create/send Multi-part MIME emails - so that you can include a nicely formatted plain-text version of your HTML email alongside it for those recipients that only view plain text.
