Mailspring currently supports automated translation of messages written in English into Spanish, Russian, simplified Chinese, French, and German using the Yandex Translation API.
To translate a message, follow these steps:
- Activate the Translations plugin in Preferences > Plugins.
- Write your draft.
- Click the Translation icon at the bottom of the message window and choose your target language.
The translation plugin will translate the body of a single email and the signature only—not the full thread history.
