Open the ops inbox at a 30-person brokerage or 3PL and it's the same pile every morning. A shipper wants a rate on Chicago to Dallas, sent two hours ago and going cold while a competitor answers first. A customer asking where their load is for the third time today. A carrier's insurance certificate that expired yesterday, on a truck that's already dispatched. Billing sitting on forty PODs nobody has had a second to chase.
None of it is hard. It's reading an email, looking something up in the TMS or on the load board, and hitting reply. But it happens two hundred times a day, and it all lands on the same dispatchers and reps who are supposed to be covering freight. So the freight waits.
