At helloly.com, all web hosting packages are alias (parked) and multidomain (addon) capable.
Aliasor parked domains are additional domains on the web space and the mail server. These domains therefore share a common web root ("/").
Multidomains, also known asadd-on domains, are independent domains and can point to their own subdirectory under ("/") in the web space.
E-mail addresses - whether parked or add-on - can always be managed completely separately from the main domain. This means that office@domain1.tld and office@domain2.tld are separate mailboxes. Of course, a forwarding can be set up, e.g. from office@domain1.tld to office@domain2.tld.
Thanks to this flexibility, several independent projects can be realized with all web hosting products at helloly.com.
