The contact management is one of the features I use regularly. I like being able to create both static lists and smart lists depending on what we are trying to manage. Smart lists are useful when we need contacts to be grouped automatically based on different conditions.
I also find the contact history very helpful. When I open a contact, I can see the previous activity and email conversations in one place. Before following up with someone, I can quickly check the earlier communication and get the context without having to search through old emails. Review collected by and hosted on G2.com.
It takes a little time to get familiar with all the options when you first start using it. Once you get used to the interface, though the day-to-day work is pretty straightforward. Review collected by and hosted on G2.com.
