I would like to use for my prelanders a master domain name and the use of subdomains for the different verticals.
I don't know what kind of names are used for pre-lander domains. I would like to clarify this doubt so I go ahead and pick the name for the domain name of my CPA...
Attention: "role based name" email prefixes such as support, webmaster, info, contact, forum, service, affiliate, admin, traffic, partners, marketing, etc., for our member accounts are not permitted. They are acceptable for a vendor listing, but not for the member email. This is due to bulk email processors scrubbing them for delivery due to extremely high bounce rates. Please apply for membership using a personalized email prefix. Something like firstname.lastname@example.org.
If we discover you signed up with a role based name we will give you only one message to change it. After 3 days your account will be removed if the email is not changed.
