I like that it is easy to use, and you can easily add multiple contacts at once! It's also really great for sending out mass emails. The only thing I dislike about this program is that it sometimes doesn't send emails as fast as I would like. That being said, if you are looking for an easy way to communicate with everyone in your office or to send large groups of people, then New Horizons is the tool for you. I have used other programs before, but none were as simple to use and so effective. I highly recommend using this program to keep all of your important information organized and easily accessible. I am able to access my email account from almost anywhere and share files with others easily. This makes collaboration much easier than having to go through several different accounts to do the same thing.
