Segments is a billion and one times more useful than (old) search for building lists. Even moreso now we have upgraded it.
Tidy users can now archive old test segments and results. Clever users can now even share their (genius, smart and elegant) segments with other users to leverage their hard work.
The interface for campaigns has undergone a major facelift and now allows users to schedule campaigns for the future in a simple 3 step process for email, SMS, letters, labels and downloads to make managing your data even more logical.
