}When
styles change, the update cascades to every email using this theme, and affectedEmailCount in the response reports how many emails were affected.
Manual style edits made on individual emails are preserved: the cascade only changes properties an email has not overridden. A per-email override is removed only when it becomes identical to the theme’s new value, after which that email follows the theme for that property.Authorizations
Bearer authentication header of the form Bearer <token>, where <token> is your auth token.
