Review on Chaos Intellect by Andre Belitz

It is very easy to use, it has all my contacts in one place so I don't have any problems finding them when needed or sending emails out quickly without having multiple programs open at once which can be time consuming if there are many people involved. Some of their features could probably do better but as long as they keep adding new ones then everything will improve over time. If your looking into an integrated solution try chaos intellect first because its free while other solutions charge quite heavily upfront and offer limited functionality compared to what we get here.
