Pardot in Multiple Languages

The Pardot user interface is now translated into French, German, and Spanish (EU). Users can easily change their locale and language settings by editing their profile in Pardot. Pardot admins change the default language and locale from the account settings page in Pardot. In accounts with Salesforce User Sync enabled, matching language settings for users are inherited from Salesforce.
