Review on Private Box by Donnie King

It is very easy for me to manage my clients with this software. I can easily add or delete users from their accounts. The interface of the program is simple enough that even someone who has no experience in managing emails would be able to use it without any problem. Sometimes there are problems when sending mass bulk messages via the service but other than that I have had nothing negative to say about private box so far. They do not charge extra fees if you send too many emails at once which is great because sometimes things go wrong especially during peak times such as holidays.
