Hi! Is it possible for publisher to publish their verified email as a contact (instead of field other contact)? Can this be done through the admin panel? Thanks

It is not clear what you mean, but fields in ocadmin are available in front as well, you would have to remove it from item-post.php and item-edit.php

I meant, perhaps that the user, when placing his ad, could place his confirmed email address in the contacts? If so, how to do it? Thanks.

I do not know what is difference between email and confirmed email and why someone would put 2 emails instead of one.

Confirmed email address is the address that the user confirmed when registering on the site. It would make sense for the user to be able to specify this address in their ad, and no other. I know message boards where it works exactly like that.

Why would a user manually enter an email address in an ad when he can just check the box to substitute a verified email address?
