Default text style

For this page: used by every text set to “Email default”. Any text can still pick its own.Font
Color

Dark mode

Apple Mail, iOS Mail and Outlook for Mac use these. Gmail and the Outlook apps ignore them and invert colors on their own. Images can have a dark version too (Image → Dark mode version). Check both in Preview → Color scheme.

Link tracking (UTM)

Added when the email is exported or sent – links on the canvas stay clean. Links that already have UTM tags are left alone. @variables work in every field.
