MessageControl has been around since 2009 and is still active. In our experience, the software has worked well for us, however we are not able to use the customer support because we cannot afford their pricing. If you want to avoid email spam, and want to protect your business from being hacked, MessageControl is worth looking into. For small businesses, the Silencer is perfect for stopping any kind of tracking in emails and messages, and the Codebreaker allows you to see exactly what is happening behind the scenes.
