It is possible to have the emails in Shopify in multiple languages, but it does take some setting up initially.
Following are instructions if you are using the Langify v2 app on your multi-language website:
Customize the emails in OrderlyEmails for Language 1, then export the code for each email into a file.
Note: You must first purchase the theme to be able to export the email template code.
Go back into the OrderlyEmails editor and update all of your emails into Language 2, then export the new code for each email into another file.
Use the below guide from Langify to add your translated emails into the Shopify admin: http://support.langify-app.com/support/solutions/articles/11000082050-e-mail-notifications
