How do I find My IP is Blacklisted ?

There are a many spam cops on the internet who maintain anti-spam database. Mail servers, ISPs and bandwidth providers get blacklists from these databases and use them in their spam filters. Domains and IP addresses that are known to send spam emails are blacklisted immediately and added to the database. When a mail server finds that a mail comes from one of these blacklist sites, then the email will not be delivered to the recipient.

Just because your IP is blacklisted by a mail server, it doesn't mean that you can never reach that subscriber. Blacklisting simply means that your email won't be delivered directly. You can contact the mail server and request to whitelist your IP address. If the provider is able to trust that you are not a spammer, then your Blacklisted IP address will be removed from the anti-spam database and the changes will reflect globally in one or two days.

Many times, the IP address of your hosting provider may be in the blacklist and as a result, your emails may not be delivered. You may be wondering why my IP is blacklisted even though I pay the required amount. Your IP getting blacklisted is not your fault because spammers use IP addresses of other legitimate persons to conceal their own identity. Without even your knowledge, you may become a victim of such a spammer and your IP may get blacklisted.

If you want an answer to the question is my IP blacklisted, you have to do blacklist test. Some servers may allow your IP address while some others may blacklist it. You can know about those servers only when you compare your IP address against known blacklists. Since it is not possible for you to go and check every blacklist available, you should use a Blacklist Monitor Tool to Check Blacklist IP Address and Blacklist Domain.
