Free subdomain instead of domain?

Hello,

You can try the free service by referring to the following URL.

I wonder, if it would be possible not to buy the domain and instead get a free subdomain? E.g. http://mail.accuwebhosting.com
I don't have a domain and I don't think it's necessary for me yet, so a subdomain would be perfect for me.
