Direct Debit Payment

Payment by direct debit at mailbox

At mailbox, you can conveniently pay for your service using the direct debit option. This method – also known as a SEPA direct debit mandate – allows payments to be automatically withdrawn from your bank account without requiring any manual action. This ensures that your account remains active and prevents interruptions due to an insufficient balance. The direct debit option becomes available once you have made at least one payment using another method, such as bank transfer, PayPal, or cash payment.

Setting up a direct debit

First, sign in to your account and open All settings | Contract and payment | Payment. There you will find the SEPA direct debit option, which allows you to link your bank account for automatic payments.

Select your preferred payment interval. In this case, only the annual interval is available. The total amount for the selected period will be charged once per year. Then confirm the direct debit agreement, the terms and conditions, and the waiver of the right of withdrawal. Finally, click Save direct debit authorisation to complete the setup.

Once the setup has been completed successfully, a confirmation message will appear. You can delete your direct debit authorisation at any time by clicking Delete direct debit authorisation. If any data is entered incorrectly, an error message will appear so you can correct it.

After setup

Once the direct debit authorisation has been saved, you will automatically receive an invoice by mail. The payment will then be withdrawn from your specified bank account at the chosen interval. In addition, mailbox will remind you 14 and 7 days before the next due date via mail so that you can ensure sufficient funds are available. You can deactivate the direct debit option at any time if you prefer to use another payment method.

Returned direct debits

  • Attention: If a payment cannot be withdrawn successfully, a returned direct debit will be triggered automatically. In such a case, please contact the Support team immediately to avoid possible suspension of your account. Common causes include incorrect bank details or insufficient account balance.

Please make sure that your bank account supports SEPA direct debits and that all required details are entered correctly. If you have any questions or need assistance, please contact the Helpdesk at mailbox.
