The software is installed on your machine. This gives you full control over everything that happens. You can supervise every aspect of message delivery process, easily add and remove subscribers and edit their details using a quick and intuitive desktop application.
Being in full control means that you can stop the software before anything goes wrong. For instance, you can stop sending before your message gets delivered to other recipients than you intended to, or when you mistyped the subject of the message meant to bring you thousand of dollars or whenever anything unexpected happens.
Being in full control means that nobody else has access to your precious mailing list. We heard of web-based services that were using email addresses of their customers for their own marketing purposes. Actually, it was one of our customers that made an experiment with a dozen or so web-based services. He signed up to one of them, added a number of email addresses and left his account to itself. To his surprise, when he logged in after a week he noticed that some of the subscribers have opted out. Because he wasn't sending any messages to these subscribers, what this means is that the service owners were sending messages to his subscribers. You see, normally he wouldn't have noticed that; if he sent a message to the subscribers he wouldn't have no way of telling that someone is abusing his mailing list.
Imagine being in full control...
