I like how easy it is to use, its very user friendly and can be used in many different ways. It has helped me with our marketing efforts by allowing us to easily track all of our leads online. Also we do not have to worry about sending out paper surveys that are getting lost or people misplacing them during mailing or giving away at events. This was my first experience using this software but would definitely recommend anyone who needs an email list manager to try it! I wish there were more features available for tracking as well as being able to create custom fields. The main benefits are ease of use, the ability to customize your own lists (segments), having access to analytics, and the fact you don't need to manage any emails yourself.
