# Adding Standard List-Unsubscribe Headers

## Goal

Add a standard list-unsubscribe header to email messages sent from a group.

---

## Background Information

In most ISPs, the list-unsubscribe header enables the inclusion of an unsubscribe link or button in the web interface of an email client. This makes it easier for recipients to unsubscribe and reduces the chance that they mark the message as spam or block the sender.

Using headers with standard values ensures that unsubscribe requests are handled correctly within the group in Mapp Engage.

## Procedure

1. Navigate to *Audience > Group Management > Groups*.
2. In the **Action** column, click the symbol next to the group.
3. Click the **Sendout Options** tab.
4. Click the symbol to expand the **List-Unsubscribe Header** area.
5. From the **Setting** drop-down list, select **Header with Standard Value (unsubscribes are handled by Mapp Engage)**.
6. Click **Save**.

After saving, a list-unsubscribe header with standard values is added to every message sent to group members. Both email-based and web-based headers are added automatically.
