Well, an Email Service Provider could very well have ten or more
servers! If I were earning money for getting mail out quickly,
putting more servers on the job would definitely be a high
priority!

On the other hand, it does stand to reason that any
general-purpose mailer can be surpassed by an equally
well-written program designed to deliver a single message to
a pre-compiled list of addresses, just ticking off successful
deliveries.
