Hi @sebastian3,
Thank you for your responses.
After my research, I found that it is currently not possible to adjust the subject field for multiple languages using Liquid syntax. The subject field is limited to only accessing these common variables listed here. Because of this, it will not be possible to adjust the subject field for multiple-language support in your yaml
file.
For now, only the message body can be modified with conditional statements to enforce multiple-language support.
In this case, I recommend upvoting the related feedback request below that asks to support localization features for email templates. Doing so will help our Engineers prioritize these features periodically based on the highest votes.
I hope this helps!
Please let me know if you have any further questions.
Thanks,
Rueben
