Paying for your mailbox account
Paying for your mailbox account is essential to ensure uninterrupted service.
This article explains which payment methods are available, how to avoid delays, and what special conditions apply.
Plans and payment terms
With the mailbox plans, your payment covers a term in months. Each payment therefore extends the term of your booked rate.
You can find the list of all plans on our website. You can change your plan in the mailbox settings under Contract and payment.
Available payment methods

Overview of payment methods at mailbox
mailbox offers several payment methods to ensure flexible and secure processing:
- Bank transfer
- Credit card
- Cash sent by post (regular letter, € only, no checks)
- Cash deposit to a bank account
- PayPal
- Direct debit (SEPA)
Currently, we do not accept cryptocurrencies (Bitcoin, Ethereum, etc.)
Information on bank transfers
For bank transfers, use only the IBAN provided by mailbox as the recipient.
Each mailbox account that pays via bank transfer is assigned an individual IBAN as the target account. This allows mailbox to automatically match your payment to your account. All payments to this account number are exclusively linked to the associated mailbox account.
Bank transfers may be processed with a delay, therefore, if payment is made too late, your account may be subject to temporary restrictions. Please make the payment at least 3–5 working days before your contract expires to avoid these restrictions.
Availability of the SEPA direct debit option
The SEPA direct debit option is available under the following conditions:
- You use the Premium or Standard plan.
- You have previously used another payment method, e.g. bank transfer or PayPal.
- You have a bank account in Europe that participates in the SEPA direct debit procedure.
For further information on direct debits, please see the relevant article: Direct debit payment
Requirements for payment by credit card
Credit card payments are processed via our payment service provider Adyen. To ensure that credit card payments work smoothly, please check the following points:
- Disable any browser add-ons that block pop-ups or scripts from mailbox or Adyen, or add the relevant exceptions. If necessary, also check for built-in blockers in browsers such as Brave. You can find details on this in your browser’s help section or documentation.
- Make sure your browser accepts cookies.
- Enable 3-D Secure for your credit card.
Avoiding restrictions caused by delayed payments
If your payment is not processed immediately, your account may temporarily be restricted (for example, sending or receiving emails may not be possible).
How to avoid restrictions:
- Use a payment method with immediate credit (PayPal, credit card).
- If you pay by bank transfer, make the payment at least 3-5 working days before the end of the contract and check your contract term in the mailbox Suite.
- If a payment is not credited within the expected time frame, please contact mailbox Support.
Anonymity and login recovery
Before making your first payment, you may receive a warning message and the recommendation to configure a password recovery method. You can easily do this in the settings under Security > Login recovery.
If you would prefer to remain anonymous, you can skip this step and select your preferred payment method. In this case, mailbox will not be able to assist you in case of password loss, as verification will no longer be possible.
Frequently asked questions
If you have any specific questions or payment issues, please contact our mailbox Support team – we’ll be happy to help.
My contract term has expired – what now?
When your contract term expires, your account will be converted into a restricted user account. Sending emails will then no longer be possible.
By making a payment, you can quickly restore your account to active status.
- If no payment is received within 30 days, your service contract with mailbox will end and your account will be suspended.
- After another 30 days, the account and all stored data will be permanently deleted.
I have received an order confirmation, so why is my contract term still the same?
Please note that an order confirmation does not constitute confirmation that your payment has been received. Please ensure you fully complete the payment process after clicking on Order with payment obligation under All settings > Contract and payment > Payment – for example, by entering your credit card details or setting up a direct debit mandate, depending on your chosen payment method. You will only receive your invoice once you have saved this information and payment has been successfully received.
Where can I find my invoice?
You will receive your invoice automatically by email 1 day after your payment has been processed.
You can find your invoices by clicking on the gear icon in the top right of mailbox Suite under All settings > Contract and payment > Invoices.
