Yes. If you do this, each message to each subscriber has to be sent out
separately; if you don't need custom header per recipient, more than one
recipient can be included for each copy of the message (typically 100
recipients per message is used), saving bandwidth and propagation delays.
If you're using VERP, of course, then you're already sending out
individual messages, and so you don't lose anything by this.
