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 Translation Lab 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 to add your translated emails into the Shopify admin:
1- Login to Translation Labs app (Shopify admin -> Apps)
2- Go to the "Translations" tab.
3- In the "Translations for language" dropdown, select the language you translated the emails into.
4- In the "Translation of" dropdown select "Email template".
5- Paste in the email code you saved from OrderlyEmails into the "body_html" field of the matching email templates.
6- Adjust the "title" fields of each email with the Subject line you would like each email to have.
Once this is all set up, you might want to preview the templates. For this, you can go to the Shopify Notifications section, click on one of the notifications and select the 'Preview' option to preview the template in each one of the languages available.
