Segments let you group contacts for future reference or create lists of subsets of contacts.

When you import contacts (Contact List in the left sidebar > Import Contacts), you can choose a segment to add them to based on the specific attributes of that list. 

From the Contact List you can filter your contacts and create a new segment by clicking Add to Segment.

You can create:

A Static Segment for contacts who match your filter right now

A Live Segment that will continuously update as contacts enter or exit the filters you set

Here's more info on managing your segments and more info on creating a Live Segment.
