Your new CakeMail has two official languages – English and French. Additional languages translated by our user base may also be available depending on your account settings. Note that these languages are not directly supported by us.
To edit the available languages, go to the Settings tab > Your Site Settings > Languages
Here you will find two sets of languages you can make available – Site Language, which will apply to your UI, and Contact List Language, which will apply to your contact lists. The latter enables all system emails to go out in that specific language.
If you would like a specific language to be the default for when users sign in and sign up for your services, be sure to click the Globe next to it.
