Sending to many recipients per message

Why is it not a good practice to send messages with more than one recipient per message?

The reason this is bad is because it requires much more computing power to parse--for example, a single message with 500 recipients versus 500 messages with 1 recipient each will take longer to send. Also, messages sent to large numbers of recipients are viewed as inherently 'spammy' by most email filtering systems.
