# How to Bulk Add DKIM Selectors to Your Domains

Learn how to bulk add DKIM selectors to your domains using CSV uploads or bulk actions.

## CSV Format for Bulk DKIM Selectors

You can bulk add DKIM selectors to your domains by uploading a CSV file. This is the fastest option when managing many domains at once.

### Video Walkthrough

### Required Columns

Your CSV must include the following columns:

<table data-id="7d91ed73-5657-4fe4-b24b-0b6e3b12c749" style="min-width: 50px;"><colgroup><col style="min-width: 25px;"><col style="min-width: 25px;"></colgroup><tbody><tr><td colspan="1" rowspan="1"><p data-id="434f1909-685e-4e70-a1c0-64d26f570d73"><code>domain</code></p></td><td colspan="1" rowspan="1"><p data-id="63b05331-b52c-4b28-97fc-adbd9b646e24">The domain you want to update</p></td></tr><tr><td colspan="1" rowspan="1"><p data-id="0eb1be22-4416-4cb8-a4bd-dcb05acee108"><code>dkim_selectors</code></p></td><td colspan="1" rowspan="1"><p data-id="64017264-54b5-4e74-86fc-3b814a09d04f">One or more DKIM selectors, separated by commas</p></td></tr></tbody></table>

### Example CSV

```javascript
domain,dkim_selectors
emailbison.com,google
stripe.com,mandrill,google
linkedin.com,google
```

### Notes

-   Multiple DKIM selectors must be **comma-separated**
    
-   After uploading, **refresh the page** to see the updates
    
-   DKIM selectors are added and verified in the background and **may take a few minutes to complete**
    

Once processing is complete, the DKIM selectors will be applied and checked automatically across all matching domains.

## Bulk Add DKIM Selectors Using Bulk Actions

Bulk Actions allow you to apply the **same DKIM selector** to multiple domains at once, directly from the Domains page. This is ideal when several domains use the same email provider.

### Step-by-Step

1.  **Select your domains**  
    Use the checkboxes to select the domains you want to update.  
    To select all domains on the current page, click the **checkbox in the table header** next to the column titles.

2.  **Click “Add DKIM selectors”**  
    Once domains are selected, click the **Add DKIM selectors** button in the bulk actions bar.
    
3.  **Enter the DKIM selector**  
    Add the DKIM selector you want to apply to all selected domains.

4.  **Apply the selectors**  
    Click **Add selectors** to apply the selector to all selected domains.
    

### Important Notes

-   The **same DKIM selector** is applied to all selected domains
    
-   Existing DKIM selectors will be **replaced**
    
-   DKIM validation status is **reset and rechecked**
    
-   Changes are processed in the background and **may take a few minutes**
    
-   Refresh the page to see updated DKIM status
    

### Tip: Group Domains by Tags

If you manage many domains, you can use **tags** to group domains that share the same email provider. This makes it easy to select the right domains before applying a bulk DKIM selector.
