“Whistl Parcels' proactive nature enhances our customers’ delivery experience and has taken the pressure off our staff, thanks to their innovative SMART Notifications platform, which identifies sequences of scan events such as bad addresses and then generates a ticket for Whistl Parcels' customer service team to rectify potential issues before they become a real problem. Ensuring our customers’ expectations are at least met and often exceeded has been instrumental in us achieving 100% positive feedback on our eBay store.”
