How can I translate emails that are sent

I would like to know where I can find the source files for the emails that ghost sends out using mailgun. I would like to translate the text in these emails.

Emails such as this one:

Hey there,

You’re one tap away from subscribing to example.com — please confirm your email address with this link:

[Confirm Email Address]

For your security, the link will expire in 10 minutes time.

All the best!
The team at Example.com

This way the templates are going to be replaced anytime ghost updates, correct?

I hope we can make a persistent translation pretty soon as a new feature. To copy-paste the translations after every update is a bit eh… clumsy.
Team Ghost, please make this possible within the Ghost framework!
