Its a lot cheaper on (queue) disk space, but still costs you bandwidth and transmission time. I have not tested our lists recently to see how many of the deliveries were being bundled together - I did do this a number of years back and it had a much bigger effect than I expected, and there are now a *lot* of people with gmail/google apps domains, all of which end up at the same SMTP servers. So this may well incur an order of magnitude increase in bandwidth usage for mail.
