# The Four Lists

> Contacts, Leads, Bounces and Unsubscribes — what lands in each and why they are kept apart.

**Contacts** holds four lists with live counts in the rail.

- **Contacts**: People you can email. The main table shows emails sent, opens, page views, last seen and last sent per person.
- **Leads**: People who came in through one of your forms, or that you added or imported, but have never signed in. See [Contacts vs Leads](https://behavly.io/help-center/contacts/contacts-vs-leads).
- **Bounces**: Addresses that failed to deliver. Suppressed from future sends automatically.
- **Unsubscribes**: People who opted out. Suppressed permanently.

> Note: Bounces and unsubscribes are suppressed on every plan, including Free. Nothing a customer needs in order to stay compliant is behind an upgrade.

#### Where The Activity Columns Come From

_Contacts, with the four tabs and their live counts across the top, and the filter rail on the left._

Page views and last-seen come from the tracking snippet. They are only populated for people the snippet has matched — an imported contact who has never visited your site shows nothing in those columns, which is accurate rather than broken.
