I thought version 2.0 was supposed to automatically render across all platforms. My test email shows perfect on my personal email, but not in Outlook. Also, it looks horrible on the iPhone 5, but perfect on iPhone 6. Is there something I can do to fix this?
I am afraid there is not such a thing as an editor that automatically render across all platforms yet
Once you create a template (or even marketo templates), You still need to test it in all clients.
In the email world, there are no established standards for rendering or displaying email. This means email services (such as Hotmail and Yahoo!) , email clients (like Outlook and Apple Mail) each have their own unique way of handling the HTML used to render an email.
same thing applies to mobile devices & versions,
