why can't i set up email with my free hosting?

I've just 'gone live' with one of my 'free' five Business Catalyst sites included with my Creative Cloud subscription. I've set up the nameserver to my url and all is working correctly.

However, I can't see how to set up email for this site!

There seems to be no email set-up options in the Admin Console?

Surely email is included in these free sites, they are not worth including otherwise

Please tell me I don't have to upgrade for email.

Can somebody please kindly point me in the right direction?
