Sending to an address that does not exist is expensive twice: the message is wasted, and the bounce lowers the sender reputation that decides whether the next message arrives at all.

Validation is the cheapest intervention available. Checking an address costs a fraction of a cent; a bounce rate above a few percent quietly suppresses an entire domain's delivery.
