What is the Contacts/Database?

The Contacts or Database page is where you can view all the contacts in your account.

Think of it as a huge list in a table view, with filters on the right side.

You can view basic information, or click on a contact to view detailed information.

If you tick the checkbox on that contacts row, you can perform additional "Bulk Actions" at the top of the page such as "Add Tag", "Add to Automation" and more.
