It's a standardized queue with a lot of features too...
You can set up filters and forwarding rules. It doesn't require a programmer or special knowledge to do so.
The queue can be viewed by one or many humans.
Messages don't have to be dealt with in-order.
read/unread state, stars, labels, drafts all allow construction of advanced workflows with no specialist knowledge.
Sure, all these things can be done better with special software, but there is a massive benefit to something that all your existing untrained and probably-not-well-paid employees can set up themselves.
