What Blacklists Are and How MxToolBox Helps

One of the most common security challenges for companies is keeping their organization’s email off of Blacklists. When your company gets Blacklisted it will cause major trouble for your business and it will slow down your communication with current customers, prospects and in general the outside world. Email communication is a critical and profit dependent function of any business and this type of communication interruption is both time consuming, costly and completely avoidable.

Most companies discover they have been Blacklisted when they start hearing complaints that their emails have not been received or messages that have been sent are bouncing back. This is really the worst way to find out your company has been Blacklisted because when customers start calling to complain there is already trouble and then you are under pressure to figure out the problem.

A Blacklist, otherwise known as a Real Time Blacklists (RBLs) is a list of problematic IPs that are monitored by Blacklist companies. There are many Blacklist companies and while MxToolBox does provide a Free Blacklist Lookup Tool, we do not control or are affiliated with any Blacklists in any shape or form. Many ISP providers subscribe to Blacklists as an inexpensive means of controlling spam and abusive email senders. There are many reasons a company may end up on a Blacklist, more often that not it’s because a company has not taken appropriate steps to secure their email infrastructure or has been compromised by spammers, hackers, or virus propagators.

Once your IP has been Blacklisted, what can you do?
