Why these are Good News?
Both SEO and Newsletter marketers require large number of dedicated IP addresses:
- Google tend to associate websites that are using the same IP address. Therefore, if a single site uses unethical SEO methods, you may want to avoid a ranking damage to other sites. Another reason is that linking methods are considered more effective if they come from external sites.
- Major email suppliers around the world (Google's Gmail, Yahoo!, Yandex and Microsoft Hotmail) limit the number of emails per minute they accept from a single IP. Multiple IP addresses can help newsletter service providers better utilize their existing instances.
