# Custom email subjects and smarter language detection

**Summary:** Customize the support email subject line, rename workspaces, and store the detected language of every message with a fallback option.

**In short:** Small tweaks that give you more control over the details.

* 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 "Unless 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 "Unless AI zone configuration") of the AI zone.

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