Selection Language translation in incoming email

When receiving an email the mail engine detects automatically the language and propose a trasnlation

But typically the first sentence like Hi Mike or Dear Mike is chosen as English although the rest remains for example in chinese

I wonder if it is possible to select the language to translate in the incoming email to read faster, than cut and paste into Google Translator

If there is a mix of languages in the message, the detection is done using the language that most of the text is in.

Is it possible there is more to the message than is in your screenshot, that is in English?
