FleetKraft emails delivery updates automatically from your company name, each with the tracking link: Booked, Driver assigned (sent once), Picked up, Delivered (with the time and who signed), Delivery failed (with the reason) and Cancelled (who cancelled it; the customer's email also gives the cancellation charge and any credit note). They go to the receiver email on the job and to the sender (the sender email on the job and the customer's email).
Switch each one on or off, separately for receivers and senders, in Settings, Notifications. All are on to start with.
