Whether you're a business that has a relationship with other businesses or you work directly with consumers, you are still focusing on people. The Contacts tool in HubSpot is your central database for keeping track of all the people and companies that have a relationship with your business. Every person who interacts with your business is a contact in the Contacts tool.
Lists works hand-in-hand with your Contacts tool and helps you organize your contacts in a way that makes sense for your business. You'll use the Contacts and Lists tools to manage your contacts and create smart and static contact lists.
