## Before you start

If you want to make settings for dunning letter mailing for more than one customer, you can do this in the [Customer classes (AR201000)](https://docs.vismasoftware.no/visma-net-erp/help/customer-ledger/customer-ledger-windows/customer-classes-ar201000/index.md) window. See: [Set up dunning letter mailing for a customer class](https://docs.vismasoftware.no/visma-net-erp/help/customer-ledger/customer-classes/set-up-dunning-letter-mailing-for-a-customer-class/index.md).

1. In the **Customer number** **Class ID** field, select the customer for which you want to configure the mailing.
1. Go to the **Mailing settings** tab.
1. In the **Mailings** table, click ![icon-add](https://docs.vismasoftware.no/media/visma-net-erp/icon-add.png) to add a new role.
1. Select **DUNNINGLETTER**.
1. In the **Email account** column, select the e-mail account you want to use as your sender address.
1. In the **Report** column, select the report you want to use to generate the dunning letter document, which will be sent as an attachment.
