Spam Policy
We have a strict NO SPAM policy. Any account that ignores this policy and sends SPAM anyway is subject to immediate termination.
Do NOT buy an email list.
Do NOT send emails to an email list you already bought.
Do NOT send emails to anyone that has not first emailed you.
Do NOT send emails to someone just because they are a domain contact on a whois lookup.
Do not be fooled by web sites that claim they can send your emails to "clean" lists, or opt-in lists. These are not acceptable.
Generally, double-opt-in lists are acceptable if they can provide proof of the double opt-in, including date, time and IP the subscriber used to complete the double opt-in.
