# Add Entries to Group Blacklist

## Goal

Add email addresses, mobile numbers, or domains to a blacklist in Mapp Engage — either the system-wide **System Blacklist** or a group-specific **Group Blacklist**. The three methods below apply to both scopes; the group-specific differences are called out inline where they occur.

> [!WARNING]
> Warning
> 
> - **System Blacklist:** When a contact is placed on a system blacklist, all contact profile data is deleted — permanently.
> - **Group Blacklist:** When a contact is placed on a group blacklist, Mapp Engage deletes all group-related information. This includes member attributes, group membership, and subscription data — permanently.

---

## Prerequisites

Your role must have the permission that matches the blacklist scope you are editing:

- **System Blacklist:** your system role must have permission `203` — **Contact Management: Edit system blacklist**.
- **Group Blacklist:** your group-specific role or group-override system role must have permission `505` — **Members: Edit group blacklist**.

---

## Procedure

You can add entries to a blacklist in one of the following ways.

> [!NOTE]
> Note
> 
> Each method works for both scopes. For a **Group Blacklist**, the navigation goes to *Audience > Blacklist > Group Blacklist* (instead of *System Blacklist*) and you must select the target group from the **Group** drop-down before continuing.

### 1. Import Entries via File

Use this method if you want to upload multiple entries from a prepared file.

1. Go to *Audience > Blacklist > System Blacklist*. For a group blacklist, go to *Audience > Blacklist > Group Blacklist* instead and select the desired group from the **Group** drop-down.
2. Click **Import**.
3. Select your file and configure the import settings:
  - **File Type**: *Text* or *XML*
  - **List Type:** *Clear-text*, *MD5*, or *SHA-256*. MD5 and SHA-256 accept hashed email addresses only. For SHA-256, see [Add SHA-256 Hashed Entries to a Blacklist](https://docs.mapp.com/docs/en/add-sha-256-hashed-entries-to-blacklist).
  - **Character Set**: e.g., *UTF-8*
  - **Import Mode**:
    - *Add* – Append entries to the existing blacklist
    - *Replace* – Overwrite the entire blacklist with your file
    - *Delete* – Remove specified entries from the blacklist
4. Click **Import**.

The logged-in user who performs the import will receive a confirmation email with the import status.

### 2. Manually Add Entries

Use this method to add individual entries directly via the UI (e.g., via copy & paste).

1. Go to *Audience > Blacklist > System Blacklist*. For a group blacklist, go to *Audience > Blacklist > Group Blacklist* instead and select the desired group from the **Group** drop-down.
2. Click **Create**.
3. Select the **List Type**: *Clear-text*, *MD5*, or *SHA-256*. With MD5 or SHA-256, only the **Email** field is available. Enter the hash values there.
4. Enter one or more entries, each on a separate line:
  - Email
  - Mobile Number
  - Domain
5. Click **Save**.

A success message will confirm that the entries have been added to the blacklist. For a group blacklist you will also receive a confirmation email.

### 3. Blacklist from the Contact/Group Overview

Use this method to blacklist an existing contact directly from the contact list.

1. Go to *Audience > Contact Management > All Contacts*. For a group blacklist, go to *Audience > Contact Management > Group Members* instead and select the desired group from the **Group** drop-down.
2. Search for the contact you want to blacklist.
3. Expand the context menu next to the contact and click **Blacklist**.
4. Review or adjust the *Email*, *Mobile Number*, or *Mobile App Alias*.
5. Click **Add to System Blacklist**. For a group blacklist, click **Add to Group Blacklist** instead.

The selected contact will be added to the blacklist.
