Translate contents of email

Hi Zoho Team
I'm deploying Zoho Mail to some of my customers with great success. But some of them complain about a feature they had on Gmail: translating the content of the email. They speak Spanish, and they do business with China. They managed to get by by using the automated translation that Google offers on Gmail from Spanish to English and back, but Zoho doesn't offer that.

So that's my suggestion: implement some kind of translation system so my Spanish speaking customers can see a Spanish translation of their English-written email.

Yours sincerely
Javier
