Enable one translation provider

  • For Google, open Settings → Google Translate, follow its setup guide, and supply a Cloud Translation API key. Enable the API in your Google Cloud project and restrict the key to the service when possible.
  • For AI, configure and enable Settings → AI Provider with a valid key, then enable AI Inbox translation.

Only one Inbox translation provider can be enabled at a time. A missing key or a disabled provider hides the Translate message action.

Translate on demand

  1. Open a message in Classic, Chat, or List Inbox and choose Translate message.
  2. Check the detected source language and select your desired language. The result appears inline. Use the original-message control to switch back.

HTML mail keeps its layout and images where supported; the translation changes the text, not the saved email. Subject and message text go to your selected provider only when requested; attachments are not sent. Provider charges may apply. Review important translations for accuracy.
