# Overview

> Curated groups of contacts for targeted event invitations

Invitation lists are curated groups of contacts used for targeted event invitations and access control. You can create lists, add or remove contacts, and use them to manage who receives invitations.

## What you can do

* **Create and manage invitation lists** with names and descriptions
* **Add contacts to lists** for targeted outreach
* **Remove contacts from lists** when they should no longer be included

| **Contacts** | The contacts included in the list        |
| **Events**   | Events that use the list for invitations |

## Key concepts

**Contact membership** — A contact can belong to multiple invitation lists, and a list can contain many contacts. Use the add/remove contact endpoints to manage membership.

**Access control** — Invitation lists can be used to restrict who can register for an event, ensuring only invited contacts have access.
