Frequently asked questions

Why are estimated delivery dates (EDDs) critical for conversions?

Accurate EDDs build trust by setting clear expectations. Displaying delivery dates on product, checkout, and tracking pages reduces purchase anxiety and boosts customer confidence post purchase encouraging repeat purchases.

How does AI improve the accuracy of delivery predictions?

Traditional EDDs often rely on optimistic carrier promises. Our AI algorithm analyzes millions of past shipments, detecting patterns such as regional delays, high-volume periods, and carrier-specific trends, and adjusts delivery dates accordingly.

Can EDDs help reduce WISMO (Where Is My Order) inquiries?

Many WISMO inquiries happen when delivery expectations are unclear. An accurate EDD sets the right expectation at checkout. Moreover, proactively updating EDDs on tracking pages reduces the need for shoppers to contact support.

How does ClickPost calculate EDDs for multi-carrier setups?

ClickPost analyzes each carrier's actual performance for specific routes, factoring in historical transit and processing times, and regional variables like holidays. This gives you one accurate delivery promise at checkout, regardless of which carrier fulfills the order.
