See every featureMaximize your profits and reduce unnecessary problems with 'AddressHero'. Incorrect delivery addresses or DHL / Deutsche Post packing stations lead to expensive misdeliveries, dissatisfied customers and rising support costs. 'AddressHero' offers address validation, recognizes and clears address errors automatically or by the customer - no manual effort required.
Some carriers (e.g. Fedex) charge extra fees or refuse delivery to PO Boxes. SafeShip validates customer addresses at checkout and blocks orders with PO Box addresses before payment. This prevents failed deliveries, avoids carrier surcharges, and saves you from manually reviewing orders. Customers see a clear message explaining why their address cannot be used, reducing support requests.
