In practice
Under CAN-SPAM, the primary purpose decides it: a receipt is transactional, a promotion is commercial, and a message with both parts is judged by its main aim. Commercial messages carry extra requirements such as an opt-out and a postal address.
Verification and sending
Verification is independent of message type; it only tells you whether the address can receive mail.
