From what information I've seen, email addresses are not included in the web hosting part of creative cloud? Why? I think many of assume that's included in most ISP hosting plans, whether or not it's charged for separately. If true, I hope Adobe will consider, along with databases, etc.
As part of your Creative Cloud package you get access to 5 webBasics websites, which indeed do not include e-mail.
However, our offering has several other plan options, for webCommerce or webMarketing for example, that include e-mail accounts. You can always upgrade your website separately to any of these plans.
