# Import a list of unsubscribed customers via CSV into Vero 1.0

> Bulk unsubscribe customers by importing a CSV with the unsubscribed tag.

To learn the full process to import customers via CSV, read [Import a list of customers via CSV](/vero-1/importexport/import-a-list-of-customers-via-csv).

If you are importing a significant number of customers the best way to unsubscribe them is to upload a CSV via the [*Import/Export*](https://app.getvero.com/imports) page.

To do this create a CSV with the list of emails you want to unsubscribe in one column and in a second column with the header *tags* and the word `unsubscribed` in that column.

```
email,tags
    chris@example.com,unsubscribed
    james@example.com,unsubscribed
    rory@example.com,unsubscribed
```

Once imported, all of the customers that have the tag 'unsubscribed' will be marked as unsubscribed.
