If a package has not been delivered after a certain period of time, Amazon automatically suggests that it may have been lost.
In fact, it is very rare that an order is lost.
The fact that you are receiving this message from Amazon is simply because we are currently unable to process all orders quickly enough. Please do not let this unsettle you. Your goods will arrive and are not lost.
If a package was really lost, DHL and not Amazon would let you know. In this case, please contact us.
