Blacklist

Targeting > Blacklist Upload

Upload, view, and manage your blacklisted users. In addition to general contact uploads, you can manage channel-based blacklists and whitelists from this flow.

• Add users to a blacklist for one or more channels.

• Remove users from a blacklist (whitelist) for one or more channels.

• Track each upload with list name, date, status, and channels.

Channel-based management

You can select one or more channels during the upload. Changes apply only to selected channels. Available channels depend on your enabled products. Options include:

• Mobile (Mobile Push), Web (Web Push), SMS, Email, WhatsApp

Blacklist Dashboard

The dashboard lists your previous uploads. Each row represents one uploaded list.

You can review:

• List Name

• Upload Date

• User Count

• Status (for example, Waiting for Approval or Ready)

• Channels affected by the upload

• Actions (view or edit depending on status)

Blacklist Upload

Use this step to add users to the blacklist.

Blacklisted users won’t receive messages on the selected channels.

1. Set a List Name.

2. (Optional) Set a Tag Name.

3. Upload your .csv or .txt file.

4. Select the channels you want to blacklist.

File format and identifiers

• Format: CSV or TXT

• Each row should represent one user

• Use a valid header name:

  Email, Mail, Phone Number, Phone, ExId, Device Token, or Token

1. Review the preview.

2. Click Approve to submit the upload.

Invalid Header Name

If the first row (header) does not use one of the allowed identifier names, the system cannot map the file correctly. In the Preview tab, the column with an invalid header (for example Phone Namber instead of Phone Number ) is highlighted.

The summary at the bottom shows:

“7 columns will be imported, 1 column will not be imported. 0 contacts will be uploaded.”

Because there is no valid identifier column, the upload cannot be approved and the system shows the error:

How to fix

1. Use a valid header name

Replace the first row with one allowed identifier column:

Email, Mail, Phone Number, Phone, ExId, Device Token, or Token

2. Remove extra separators

3. Ensure each row has exactly one value

4. Clean hidden characters

Whitelist Upload

Targeting > Whitelist Upload

Use this step to remove users from the blacklist.

This makes them eligible again on the selected channels.

1. Set a List Name.

2. (Optional) Set a Tag Name.

3. Upload your .csv or .txt file.

4. Select the channels you want to whitelist.

5. Review the preview.

6. Click Approve to submit the upload.

Whitelisting does not bypass consent rules.

Users still need valid permission per channel.

Blacklist vs whitelist priority

For each end user, Netmera keeps a history of blacklist and whitelist records by channel. If a user has both types of records:

• The most recent record wins.

• If a newer whitelist record exists after a blacklist record, the user is treated as whitelisted (eligible) on that channel.

This ensures that changes made through your latest uploads are always respected and traceable.

View user status in People

Targeting > People > User Details

In User Details, you can see the user’s blacklist/whitelist status per channel. The information is shown in a clear, readable list.

If the user is not blacklisted on a channel, no record is shown for that channel.

If the user is blacklisted on a channel, a record is shown in this format:

• Added to Mobile blacklist via “listName” on "date".

• Added to Web blacklist via “listName” on "date".

• Added to SMS blacklist via “listName” on "date".

• Added to Email blacklist via “listName” on "date".

• Added to WhatsApp blacklist via “listName” on "date".
