Yes. When your school has automatic translation turned on, every message email includes a small en Español link at the top. Parents who receive the message in Spanish see an In English link instead. Clicking the link opens the message, translated, on your ClassroomParent site.
The link is included whether the message was sent right away, scheduled to be sent in the future, or sent as a preview to yourself, so you can try it out before your message goes to everyone.
To turn automatic translation on, an admin can go to Admin/Settings and set Allow content to be automatically translated to Yes. Translations are created automatically and may not be perfect, so keep your messages clear and simple when you can.
