# How do I create and update an opt-out list in Sarbacane Contacts?

Create an opt-out list, add contacts or domains to it, then link it to your campaigns.

To stop writing to certain contacts, create an opt-out list in Sarbacane Contacts, add their addresses to it, then link it to your Sarbacane Campaigns campaigns. If you change nothing, your campaigns use the default opt-out list.

## Prerequisites

-   Access to Sarbacane Contacts and Sarbacane Campaigns.
    

## Steps

### Create an opt-out list

1.  In the left menu of Sarbacane Contacts, open **Contact lists**, then at the top right click **Create a list**.
    
2.  Choose **Opt-out list**, then click **Select**.
    
3.  Add the contacts: **Import a file (.xlsx, .txt, .csv)**, **Manual entry** or **Copy / Paste**.
    

### Add or remove contacts

1.  In **Contact lists**, open the **Lists of unsubscribed** tab and click the list.
    
2.  To add contacts: at the top left, next to the list name, click **•••**, then **Add unsubscribers**.
    
3.  To exclude every address of a domain name: open the domains tab, then **•••** › **Blacklist domains**.
    
4.  To remove a contact: click its row to select it (Ctrl + click to add others), then **•••** › **Delete**.
    

### Link the list to a campaign

1.  In Sarbacane Campaigns, in the **Recipients** step (once recipients are added), click **•••** at the top right, then **Unsubscribe list(s)**. You can also go through the **Message** step, in **Advanced settings**.
    
2.  In the **Opt-out lists** window, click **Add a blacklist** and choose your list. Repeat to link several.
    
3.  At the bottom of the window, click the green check mark to confirm.
    

**Important**: a duplicated campaign keeps the opt-out lists of the original campaign. Check them after each duplication.

## Expected result

Before sending, contacts in the linked lists are set aside: they appear in the **Unsubscribers** tab of the **Recipients** step. Each recipient who unsubscribes from this campaign is automatically added to these same lists.

## Troubleshooting

### An unsubscribed contact received my campaign

Check in this order: the list containing them is linked to the campaign (**Unsubscribe list(s)**); the campaign was not duplicated from a campaign linked to other lists; the address in the list is exactly the same as the recipient's.

### "Unsubscribe list(s)" doesn't appear in the ••• menu

The campaign has no recipients yet. Add some, or go through the **Message** step, in **Advanced settings**.
