Payment at mailbox

Payment Information for Your mailbox Account

Timely payment for your mailbox account is essential to ensure uninterrupted service. This article explains the available payment methods, how to avoid delays, and outlines important details to keep in mind.

Plans and Payment Terms

Since 2021, mailbox plans no longer operate on a credit balance basis. Instead, payments directly book a subscription period in months. Each payment extends the duration of your selected plan accordingly. You can find the list of all plans on our website. Upgrades can also be made via the Contract or the Change plan section under Contract and payment in your account settings.

Available Payment Methods


Figure 1: Under the 'Extend plan' submenu, you can choose from various payment methods.

mailbox offers a range of payment methods to ensure secure and flexible transactions:

  • Bank transfer
  • Credit card
  • Cash by mail (standard letter, euros only, no checks)
  • Cash deposit to a bank account
  • PayPal
  • Direct debit (SEPA)

We currently do not accept cryptocurrencies (Bitcoin, Ethereum, etc.).

Note: Payments made via bank transfer may be subject to delays in processing, which can temporarily restrict access to your account. Please make sure to pay in advance to avoid any interruptions.

Availability of SEPA Direct Debit

SEPA direct debit is not available for all plans. It is currently offered only for mailbox Premium and Standard plans, but not for the Light plan. This is due to different billing models.

Note: Please note that SEPA direct debit is only available if you have previously used another payment method. I. e. if you have a fresh account and you have never made a payment to your contract, you can't use direct debit.

Avoiding Account Restrictions Due to Payment Delays

If your payment is not processed immediately, your account may be temporarily restricted (e.g. sending or receiving emails may be disabled). To avoid this:

  • Use a payment method with instant crediting (PayPal or credit card. Sofort and Giropay will not be credited immediately!).
  • If you choose bank transfer, make sure to pay in advance and monitor your balance in the mailbox portal.
  • If your payment is not credited within the expected timeframe, please contact Contact Support

Received a Warning Message?

Anonymity and Password Recovery

Before making your first payment, you might receive a warning message suggesting that you set up a password recovery method. You can do this easily via the "Edit personal data" button. If you prefer to remain anonymous, you can skip this step and proceed by selecting a payment method using "Make a payment now".

Please note: in this case, mailbox cannot assist you if you lose your password, as there will be no way to verify your identity.

Troubleshooting

Common issues during the payment process may be caused by browser plugins or security settings that block data transmission, or by entering an incorrect IBAN (account number).

Important: mailbox assigns a unique IBAN to each account. Please double-check all details. Refunds may not always be possible, so proceed carefully.

Disable Browser Add-ons

If you are using browser add-ons, make sure that scripts from both mailbox and our payment service provider Adyen are allowed. This also applies to built-in blockers, such as those included in browsers like Brave. Refer to your browser’s help or documentation for specific instructions.

Use the Correct IBAN

For bank transfers, only use the IBAN provided by mailbox.

Each mailbox account that uses bank transfer is assigned a unique IBAN. This allows us to automatically match your payment to your account. Payments sent to this IBAN are exclusively linked to the associated account.

My Plan Has Expired – What Now?

If your plan has expired, your account will be downgraded to a restricted user account. In this state, sending emails is no longer possible. You can restore full functionality by submitting a payment.

If no payment is made within 30 days, your contract with mailbox will be terminated. Your account will be locked, and after an additional 30 days, it will be permanently deleted, including all stored data.

Where Can I Find My Invoice?

You will receive your invoice via email one day after your payment has been processed.

All previous invoices are available under All settings > Contract and payment > Invoices.


Figure 2: In the 'Invoices' submenu, you can view all your invoices at any time.

Note: If you experience payment issues, please contact our support team — we're happy to help.

Please note that the scope of support services may vary depending on your selected plan.
