# Where Contacts Come From

> Build the contact data you'll reach out to: unified profiles, working lists, and verified details from external sources.

Everything in this section answers one question — *who are we talking to?* Start from a Smart List you build by hand, or pull contacts in from external data sources, then enrich them until you have enough to run outreach.

## In This Section

* **[People](/find-enrich/people)** — Unified profiles that merge the same person across Smart Lists, sequences, campaigns, conversations, and your inbox.
* **[Smart Lists](/find-enrich/smart-lists)** — Spreadsheet-style tables of contacts and data, with per-row AI actions.
* **[Lead Data](/find-enrich/lead-data)** — Look up and import contacts from external sources: Enrichment, People Search, Sales Navigator, and the credits that pay for them.

## Where Contacts Come From

| Route                                                       | Best for                                           |
| ----------------------------------------------------------- | -------------------------------------------------- |
| Type or paste into a [Smart List](/find-enrich/smart-lists) | Contacts you already have                          |
| [Enrichment](/find-enrich/lead-data/enrichment)             | Filling in details for one known person or company |
| [People Search](/find-enrich/lead-data/people-search)       | Building an audience from scratch using filters    |
| [Sales Navigator](/find-enrich/lead-data/sales-navigator)   | Turning a LinkedIn search into a list              |
| A CRM [integration](/settings/integrations)                 | Syncing contacts you keep elsewhere                |

All of them land in the same place: a Smart List you can enrich, score, and feed into a [sequence](/engage/sequences).
