# Custom email subjects and smarter language detection

November 20, 2023
 Small tweaks that give you more control over the details.  IntegrationsLanguages
 - The subject line for emails delivered to your specified customer service email is now customizable via the Configuration tab of the AI zone.
 - You can now [adjust the workspace names](https://unless.com/en/dashboard/account/workspaces) listed at the top right corner.
 - Added article visibility properties to the Salesforce integration such as include/exclude options.
 - We’ve made some changes to make the input field in the chat clearer.

**Language detection**

 - We now store the determined language of each message and answer which should make it easier to identify outliers and errors.
 - Additionally, you can add a fallback language for cases where the language cannot be confidently determined. You can do this via [the Configuration tab](https://unless.com/en/dashboard/workspace/configuration) of the AI zone.

**Fixes**

 - The chat no longer crashes in the case of an empty message.
