Email localization

[Andriy-K]

Hi mozillas, thanks for great product.
I have a question regarding email localization. I checked how it works, and I see that localization depends on user profile data in the request received, for example, by the v1/first-forwarded-email/ endpoint. However, I wonder, where does this request and user profile come from?

Hi @Andriy-K! When you sign up for a Mozilla account, it records the browser's language setting, and we use that for forwarded emails. When you are using the website, we use your broswer's language setting to pick the language. See Accept-Language header for more details.

Thanks for replying @jwhitlock .
I have strange situation, I do have in browser Accept-Language: uk,en-US;q=0.7,en;q=0.3 and UI of https://relay.firefox.com works correctly by showing me Ukrainian language. But all my emails sent by mozilla relay have a email header and footer wrappers in Russian language. What could be wrong or what additional logic is used for applying particular language in emails header and footers?

@Andriy-K For forwarded emails, the language is determined by the Accept-Language that was set when you signed up for your Mozilla Account. Unfortunately, as far as I know there isn't currently a way to change that language :/
