# Manage contact lists and sources

The List Manager enables you to efficiently manage contact information added or imported from different sources (including [custom sources](https://doc.sitecore.com/xp/en/users/93/sitecore-experience-platform/create-a-custom-source-definition.html "Create a custom source definition")) and systems such as the Email Experience Manager or through Marketing Automation. The origin of the included lists or sources is displayed in the **Included lists and sources** section. It is from this section that you remove obsolete sources and add new sources.

Included lists and sources are updated when you:

- Upload contacts from a Comma-Separated Values (CSV) file.
- Add contacts using the **Add new contacts** dialog box.
- Include contacts from another contact list.
- Convert a segmented list to a contact list.
- Add contacts from the Email Experience Manager.
- Add contacts through Marketing Automation.

1. On the Sitecore Launchpad, click **List Manager**.
