If your e-mail notification templates are displaying in a single language and not in the user’s default locale as you expect, check to see what notification template is selected. You can select a default template or a localized version of the template. When you select a localized template, the language of the localized template is used regardless of the user’s default language. When you select the default template (the template without a locale code), the e-mail is in the user’s default language (if the default is a supported language).
