Common Royal Mail operational scenarios
UK Shopify merchants shipping domestically
You run a UK-based Shopify store and Royal Mail is your primary carrier. You need labels and tracking to flow automatically without manual Click & Drop entry.
UK sellers shipping internationally
You sell globally from the UK and need Royal Mail international labels with customs declarations generated from your order data.
Multi-channel UK brands scaling fulfillment
You sell on Shopify, Amazon UK, and eBay UK. Royal Mail labels and tracking need to sync across all channels from one place.

What teams should design around early
Weight and size limits vary by service
Royal Mail has strict weight and dimension limits that differ between services. Items over 2kg may need Parcelforce or an alternative carrier.
Compensation limits on standard services
Standard Royal Mail services have low compensation limits for lost or damaged items. Consider Special Delivery for high-value orders.
Collection scheduling
Royal Mail collections must be scheduled in advance. Ensure your dispatch schedule aligns with available collection windows.
