[wp-hackers] Email batch sending

[Pasquale Puzio]

Hi all,

I would to send thousands of emails automatically partitioning them in a
certain fixed quantity for each hour. These emails are not sent manually but
they are generated by some special events.

I know that WordPress provides a cron system. Anyone of you has some useful
link to suggest me? Is there some plugin or PHP library that can help me?

Thanks
