I learned something new today about the dangers of
advertising brand new domains.

Seems there’s an organization called Outblaze that some ISPs
use to help filter spam. One of the factors they use to
determine spam is the newness of a domain name.

Yusuf Goolamabbas of Outblaze describes the data as coming
from spam trap message body analysis: “We have an extensive
set of spamtraps. The emails to these accounts are analysed
and URIs are extracted. For any domain found in these
emails, we check for ‘new’ and if so, its blocked.” In this
case, ‘new’ is defined as the domain being registered within
the last 90 days. This newness should help prevent
legitimate domains from being listed since spammers
routinely register new domains, use them for a only a few
days or weeks, then move on to a fresh domain for their spam
advertised sites.

So what can you do about this? Register domain names early
in any project and don’t plan large email campaigns until
the domain has aged over 90 days.

I personally saw a couple of my own domains blacklisted
because of this.

More info on tripping spam filters because of domain
names here.

My friend Jeff Walker has more detail on getting blacked out.
