What I would do is push all the records that need to be mailed to a table
(or flag them in a table they already reside in). Then you can have BDRB set
up to run once an hour - it picks up the most recent (or the oldest, or some
other combination, your choice) and mails them, 250 each hour until there
are none left. You can add in records whenever you want, confident that they
will go out eventually.
Trying to do it another way, i.e. sending out 250, then setting up a
schedule to send out the rest, could be done but it's a lot harder and
probably doesn't get you much more, especially for the 251st and onward
email recipients, plus you then have to deal with the issue of that happens
if you need to send another batch of 250+ within an hour of the first being
sent - what to do then?
You can read more about BDRB cron scheduling at

Hope this helped some.
