I like that it is easy to track contacts and send emails. It also has a great interface, which makes it easy to use. You can also set up filters to narrow down your search results. The only thing I disliked was how it would sometimes stop working during an emailing session. There were times when it would not respond or send emails at all. Other than that, everything worked well. I recommend using this tool. It's very helpful in keeping track of my leads and contacting them. It's also easier to schedule meetings with people who have been contacted through this tool.
