Blacklisted IP is the IP address, which has been banned or blocked from delivering emails because of spam related complaints. Blacklist is a database that consists of banned IP addresses that are particularly generating Spam. When a complaint regarding Spamming is reported to one of the blacklist company, the spam generating IP address is added to a banned or blacklisted IP address list, called the blacklist.
If your IP address is responsible for generating Spam emails, one complaint is enough to place your IP in a blacklist. Most of the major email servers refer to the blacklists to filter incoming emails. Once your IP address is blacklisted, your emails will be blocked by the email servers.
There are three different types of Blacklists:
Temporary Blacklist:
Your IP address is blacklisted for some hours. IP address blacklisted, temporarily, will have their emails blocked for some hours. After a few hours, the blacklisted IP address is removed from the blacklist.
Permanent Blacklist:
Once your IP address is added to a permanent blacklist any email server configured to block emails from this list will never receive email from that range of IP addresses again.
Comprehensive Blacklist:
This is the most detrimental. As it not only blocks a single IP address but also blocks all the IP addresses next to it. For example, if the IP address 192.156.85.86 was added to a comprehensive blacklist then all IP addresses similar to 192.156.85.86 will also be blocked.
Email marketers and individuals, who use emails to reach prospects and customers, should regularly monitor blacklists. It is imperative to know, whether your IP is in a blacklist or not, to increase email deliverability rate. There are many online web-based systems, to help you monitor your IP addresses. One of them is blacklistedip.com, it monitors your IP address all the time and provides instant email notification, whenever your IP lands in a blacklist.
