Franking machines that have been purchased or leased and whose use by you has been specified in a contract that you have concluded with Deutsche Post AG.
The "SendPro Mailstation from Pitney Bowes Deutschland GmbH and "imnudoo" online franking from Frama Deutschland GmbH are not conventional franking machines, but rather advanced label printers that use the Internetmarke stamp. Users of these systems do not have a franking machine contract and are not suitable for "Verfolgen Brief Frankiermaschinen" (mail tracking franking machines).
Please note: To preserve postal secrecy, customers may only use single-user franking machines with the service, i.e., franking machines that are used exclusively by you to frank your own items only. Multiple-user machines are not permitted, i.e., those that are available to both you/your employees for business purposes as well as to others who, for example, share your office space.
