I wrote a newsletter app that does this (and more) and is about to become public, just as soon as I clean it up and make sure it works outside the site it was developed for... might be too late for you though. It uses the method that Rajesh describes in his reply - it create a Delivery record for each recipient, with a foreignkey pointing to the newsletter to be mailed. An hourly cron job pulls a certain amount of Delivery entries (can't just send all of them at once because some hosting providers think you're a spammer if you do that), sends them and marks them as "sent". The newsletter object itself gets marked as "sent" as soon as the Delivery objects are created, so you won't send it a 2nd by accident while its delivery is pending. As for knowing that the delivery has finished, adding that should be easy - just count unsent delivery objects. I use a "send" button in the admin newsletter list view (changing to "sent" after the send), the delivery count could easily be displayed next to it. Let me know if you want a look at the mailing code before the whole app is available.
