I do not see my domain mail accont in CRM mail templates

I got email account on my domain DVENERGO.RU. It is linked with zoho mail, and made default. All works good.

But I cant see it in my email templates. I wish to send emails to my customers using my domain email name.

It is only choice of my user account gmail adress, but no my domain email adress.

What to do?
